Abstract Abstrak. Loquat (Eriobotrya japonica Lindl.) is a flowering plant that belongs to the Rosacea family. The loquat has many health benefits. Cultivation and information about loquat plants in Indonesia are still limited, so they are rarely found and known by the public. Limited information and data regarding loquat plants is also an obstacle to the development of loquat plants. Research on loquat plants aims to analyze the morphological characters in three districts, namely, Karo, Dairi, and Simalungun districts. This research was conducted using a descriptive method. The analysis of the morphological characteristics of loquat plants using morphological data scoring into binary data. The similarity between individuals was analyzed using clusters with the NTSYS program version 2.0 with the UPGMA method of the SimQual function. Morphological Observation Results Loquat plants (Eriobotrya japonica Lindl.) in Karo, Dairi, and Simalungun Districts have uniform characters in the morphology of stems, leaves, and flowers. However, the observed fruit and seed morphology showed different characters. Different characters exist in the shape of the fruit and seeds. The morphological similarity level of loquat plants was grouped at a similarity coefficient value of 95%. Clusters I and II have the highest similarity with a coefficient value of 100%. Cluster III has the lowest similarity with a coefficient value of 97%.

Nepenthes spp. is a typical plant of Southeast Asia especially Indonesia which has a special leaf modification called a pitcher. The largest number of Nepenthes spp. species in Indonesia is on the island of Sumatra. The purpose of this reseach was to identify and analyze cluster Nepenthes spp. from South Sumatra based on morphological characteristics. The specimens were collected from the forest of Tekorejo Village, Air Itam Village and cultivation location in Palembang city of South Sumatra. Identification of morphological characters performed on the characteristics of root, stem, leaves, and pitcher. The morphological data is used for cluster analysis using NTSYS software version 2.02. The identification results showed 9 variants of Nepenthes spp. which belong to the species N. mirabilis, N. gracilis, and N. sumatrana. Dendogram analysis results form two main clusters with a similarity value of 22%. The first cluster consists of N. mirabilis and N. sumatrana. The second cluster consists of N. gracilis. Based on the results of this study can be concluded that the species Nepenthes spp. South Sumatra is N. mirabilis, N. gracilis, and N. sumatrana. The results of this study will be dedicated to updating information about the existence of Nepenthes spp. from South Sumatra and his cluster.

Acanthophyllum, with ca. 90 spiny cushion-forming species, is one of the largest genera of Caryophyllaceae. Although taxonomic utility of seed morphology has already been highlighted in different genera of Caryophyllaceae, the systematic value of seed characters in Acanthophyllum has not been adequately addressed. In order to evaluate the application of seed morphology in infrageneric classification of Acanthophyllum, we surveyed seed characters in the five Iranian sections of Acanthophyllum. Seed morphology of 32 accessions of Acanthophyllum representing 21 species and four sections were investigated using scanning electron microscopy. Seed morphological characters of two species from one additional section were included based on previous studies in the Caryophyllaceae. Seeds in the majority of examined species are oblong in outline. Five types of seed surface can be considered: reticulate, reticulate-papillate, colliculate, colliculate-papillate, and colliculate-columellate. Papillae type is a reliable character for separation of certain natural groups within Acanthophyllum. Seed features provided strong evidences for separating sections, especially the following ones: Acanthophyllum, Macrostegia and Pleiosperma, whose seeds showed a high degree of uniformity among the sampled species. Morphological characteristics of seeds were less useful for discriminating Acanthophyllum species. While seed characters are consistent within individual populations, they can vary among different populations of an individual species. Our results show that variation in seed morphological characters are in agreement with phylogenetic patterns within Acanthophyllum.

Salvia chloroleuca Rech. f. & Aell. is one of the perennial species of the Lamiaceae family in Iran, which has antimicrobial and antitumoural properties. In the current research, the morphological variables and hydrodistilled essential oils of two populations, from Polor and Neyshabur, of this species were evaluated. We studied 10 and 40 individuals for morphometrics and essential oils, respectively. Morphological data were analyzed using SPSS. Furthermore, the extracted oils were analysed using GC and GC/MS. The qualitative morphological characteristics were stable between the populations, while the quantitative ones highly varied. The one-sample variance test revealed significant differences for most of the studied features. The yielded oil highly differed between these populations. The first and second main groups of compounds were the same for both populations, but with different percentages. However, the third and fourth main groups of compounds were not similar. Furthermore, the main compounds of essential oil differed between the studied populations. The major compounds of the Polor population were: β-pinene (22.7%), α-pinene (18.3%), germacrene D (7.7%) and sabinene (6.6%). However, spathulenol (19.8%), bicyclogermacrene (11.4%), p-cymene (10.8%) and β-pinene (10.4%) constituted the major compounds of the Nyshabur population. In total, the Neyshabur population had higher amounts of sesquiterpene and oxygenated compounds than the other population. The results indicated that in this species the quantitative morphological characters and essential oils were strongly affected by environmental factors.

Abstract. Rindyaastuti R, Hapsati L, Wibowo AT. 2021. Analysis of morphological characteristics and phenetic relationship of ebony (Diospyros spp.) in Indonesia. Biodiversitas 22: 2738-2753. Diospyros L. (Ebenaceae) is an economically important genus that covers over 500 plant species. Members of this group are known to produce hard, dark, high-quality timbers known as ebony trees, while other members are known as persimmon trees. There is limited information on the morphological characters and phenetic relationship of this genus from Indonesian archipelago. In this work, we reported the phenetic clustering of 14 species of Indonesian Diospyros, based on plant habit, stem, leaves, and fruit characters, which was analysed using UPGMA and Jaccard similarity index. The phenetic dendrogram divided the 14 species of Diospyros into two main clusters which separating Subgen. Maba and Eudiospyros. Further, subgen. Maba was clustered into a single cluster while subgen. Eudiospyros was divided into 3 sub-clusters as sister groups. The clustering in Eudiospyros was supported by low SI and bootstrap value, demonstrating the high morphological variation of the subgenus. The sectional separation of Diospyros spp. was considered as paraphyletic. In general, our phenetic clustering exhibited suitability and relevancy with previous classification. Fruit size and trichomes are very important in this phenetic clustering, especially to form Eudiospyros subgenus. Fruit trichomes were also special characters related to biogeographical distribution following the Wallace line theory.

Morphological Description

Four putative “Chantransia” isolates were collected from four locations in Hubei and Yunnan Provinces, China. Morphological analyses were conducted on all isolates. Two specimens (HB26 and YN2) fit the morphological description of A. pygmaea, while the other two isolates (YN1 and YN3) varied in morphology, but were within the circumscription of Audouinella hermannii. Due to the fact that the morphological characters of the “Chantransia” stages of order Batrachospermales and the species of genus Audouinella are too similar to be distinguished, a molecular analysis was performed to clarify the phylogenetic position of these four isolates based on rbcL and psbA sequences. Two “pygmaea” specimens collected from Jiugong Mountain, Hubei Province (HB26) and Shimen Gorge, Yunnan Province (YN2), such as S. jiugongshanensis and S. shimenxiaensis, are proposed primarily based on the DNA sequence data generated in this study. The description of these two new species provides more molecular data for phylogenetic analysis of the genus Sheathia. In addition to these newly described species, the results strongly support that those “hermannii” isolates (YN1 and YN3) collected from Yunnan Province were the “Chantransia” of S. arcuata. However, their gametophyte stages have not been found, meaning that critical diagnostic morphological features were unavailable and molecular methods were the only means for ascertaining their phylogenetic position. Considering the extensive application of the rbcL and psbA genes in phylogenetic analyses of freshwater red algae, we recommend using these two genes to identify species when no morphological characteristics are available.

73 taxa of the genus Scrophularia (Scrophulariaceae) from Turkey have been investigated using light stereomicroscope (LM) and scanning electron microscopy (SEM) in order to describe their seed morphological characteristics and to evaluate the diagnostic value of these features as a contribution to the genus systematics. The seeds are oblong, ellipsoid, ovoid or obovoid in shape and light or dark brown, blackish-brown to black in colour. The seed length ranges from 0.41 to 2.04 mm and seed width from 0.24 to 1.33 mm. All investigated taxa have bireticulate-alveolate ornamentation with vesicles on the corners of secondary reticulum cells except of S. zuvandica. The alveoli are oblong, orbicular and linear with a size of 7.63–143.1 × 21.62–314.2 µm. Cluster analysis and principal component analysis have been used to determine the contribution of seed morphological characters to the taxa relationships. Numerical analysis has revealed that the seed size and the secondary reticulum properties have significant importance in taxonomy of the genus for distinguishing taxa from each other.

Tetranychus Viennensis

AbstractNucleotide sequence variation and morphological characters were used to study the evolutionary relationships among nine tetranychid mites species. A phylogenetic study of this family based on mitochondrial cytochrome oxidase subunit I (COI) sequences had previously placed the species Tetranychus viennensis Zacher outside the other species analysed in the genus. Phylogenetic relations within the genus were re-examined with the addition of the species Tetranychus quercivorus Ehara & Gotoh, which is morphologically close to T. viennensis. Another region of the genome, the second internal transcribed spacer (ITS2) of ribosomal DNA, was also studied and proved to be of considerable interest at this taxonomic level. Both COI and ITS2 sequences indicated a close relationship between T. viennensis and T. quercivorus, which are grouped together and distinct from the other Tetranychus examined. The two species display morphological characteristics such as the absence of a medio-dorsal spur on all empodia of the legs of both sexes and the presence of anastomosing peritremes. This distinguishes them from the other members of the genus Tetranychus. The convergence of molecular and morphological data suggests that T. viennensis and T. quercivorus should not be classified in the genus Tetranychus. It is proposed that the genus Amphitetranychus Oudemans should be restored for classification of these species. Finally, a key to the Tetranychini tribe genera with one pair of para-anal setae is presented.

An updated checklist of Mozambican marine brachyuran crabs is generated based on an exhaustive revision of the existing literature, together with the additional records provided by the specimens collected throughout the three “MOZAMBIQUE” surveys carried out in Mozambican waters during three consecutive years (2007–2009) by the Instituto Español de Oceanografía, (Spanish Institute of Oceanography, IEO). A total of 269 species, grouped in 15 superfamilies, 26 families and 172 genera are reported in the checklist, and a detailed inventory is produced with the list and remarks about the brachyuran species collected. Thirty-nine crab species belonging to 19 families were identified based on morphological characteristics and/or genetic tools. DNA barcode sequences (16S rRNA and/or COI) were obtained for 37 species, including 16S and COI sequences that are new for 26 and 14 species, respectively. Colour photographs of fresh specimens illustrate the comments about most species, being the first time that the original colour pattern is described for some of them. New records in Mozambican waters are reported for the species Paromolopsis boasi, Mursia aspera, Carcinoplax ischurodous, Tanaoa pustulosus, Euclosiana exquisita, Oxypleurodon difficilis, Naxioides robillardi, Samadinia galathea, Cyrtomaia gaillardi, Paramaja gibba, Pleistacantha ori, Parathranites granosus, Parathranites orientalis, Ovalipes iridescens and Charybdis smithii, and second records for Moloha alcocki, Samadinia pulchra and Charybdis africana. In addition, Raninoides crosnieri, S. galathea and P. ori were collected for the first time after their descriptions. The female of Samadinia galathea is described for the first time, and a potential new species of Mursia is reported. Some records expand the known bathymetric range of certain species and/or their general distribution. New molecular and morphological data suggest the necessity of the revision of P. boasi, R. crosnieri, C. africana and the genera Platymaia and Carcinoplax. The variability and taxonomic validity of some morphological characters in brachyuran systematic is discussed.

Oreochromis mossambicus is currently receiving much attention as a candidater species for aquaculture programs within Southern Africa. This has stimulated interest in its breeding cycle as well as the morphological characteristics of the gonads. Limited information is available on SEM and TEM observations of the male gonads. It is known that the testis of O. mossambicus is a paired, intra-abdominal structure of the lobular type, although further details of its characteristics are not known. Current investigations have shown that spermatids reach full maturity some two months after the female becomes gravid. Throughout the year, the testes contain spermatids at various stages of development although spermiogenesis appears to be maximal during November when spawning occurs. This paper describes the morphological and ultrastructural characteristics of the testes and spermatids.Specimens of this fish were collected at Syferkuil Dam, 8 km north- west of the University of the North over a twelve month period, sacrificed and the testes excised.
