<p><em>Bulbophyllum ovalifolium</em> (Blume) Lindl., an epiphyte orchid species was collected from several region in Bali and maintained in “Eka Karya” Bali Botanic Garden. The orchid is a common and widespread species in Southeast Asia, thus makes the flower has high variability. Here a study through morphological characters on the flower was done to give more information and understandable of characteristic range. The species was found at altitude range 700 to 2000 m a.s.l., the morphological observation was conducted on 2014 to 2015 particularly in the flowering season. There were three variants of flower based on the differences on size, colour, and the lip. The character on lip surface was found as spot character with three types of surface: coarsely verrucose, scattered verrucose, and glabrous.</p><div><p class="Els-keywords"><strong>Keywords:</strong> Bali; Bulbophyllum ovalifolium; morphological variation; orchidaceae; orchidi.</p></div>

Eulimnadia Packard, 1874 is the most species rich and widely distributed genus within the Limnadiidae (Reed et al. 2015). Species identification relies primarily on egg morphology as adult morphological characters show high variability, sometimes within the same populations and hence of little use (Rabet, 2010; Rogers et al. 2012). Seven species are currently known from the Indian subcontinent (sensu Rogers & Padhye 2015) and SE Asia (Rogers et al. 2016). Of these, four species, viz. E. compressa (Baird, 1860), E. michaeli Nayar & Nair, 1968 and E. indocylindrova Durga Prasad and Simhachalam, 2004, E. azisi Babu and Nandan, 2010 are known from peninsular India (Padhye et al. 2015; Rogers & Padhye, 2015), although, much of this region remains unstudied (Padhye pers. obs.). With this background, we present a new Indian record of E. khoratensis Rogers, Dadseepai and Sanoamuang, 2016 from the Western region of Maharashtra state, India, extending its distribution a few thousand kilometers westwards.

Febjislami S, Kurniawati A, Melati M, Wahyu Y. 2019. Morphological characters, flowering and seed germination of the Indonesian medicinal plant Orthosiphon aristatus. Biodiversitas 20: 328-337. Orthosiphon aristatus (Blume) Miq is a popular medicinal plant in Southeast Asia. The morphological variation of O. aristatus is narrow and information on flowering and seed germination is limited. This study aimed to determine the morphological characters, flowering and seed germination of O. aristatus. The study was conducted on 19 accessions (ex situ collections) of O. aristatus from West, Central and East Java. It was found that the differences in morphological and flowering characters were mainly based on shape and color. The dominant stem color is strong yellowish green mixed with deep purplish pink in different proportions. The dominant leaf shape was medium elliptic. O. aristatus flower has three kinds of colors: purple, intermediate and white (the most common color). O. aristatus has heterostyled flower with a long-styled morph. The stigma has two shapes: open and close (the dominant shape). The open and close stigma was found in Tuban accession, the open stigma was found in Pamekasan accession. O. aristatus accessions have a narrow diversity of 84% similarity rate. O. aristatus started flowering at 4-5 weeks after planting and blooming 2-3 weeks later. O. aristatus seeds begin to germinate on the fourth day and take about eight days to grow from seedling to become complete sprouts. Count I ranged from day 5-6 and count II on days 10-11. Tuban accession has the highest germination rate of 72.97%. The results of this research can be considered as new information, regarding information about the diversity of morphological, flowering characters and the ability of O. aristatus seed to germinate.

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%.

The little-known Aloe labiaflava (Asphodelaceae subfam. Alooideae), which has for long been regarded as a hybrid between A. davyana and A. longibracteata, is reinstated as an accepted species endemic to a small area in the western Mpumalanga province of South Africa. It differs from both A. davyana and A. longibracteata in several reproductive morphological characters not present in these two species, especially by almost invariably producing only a single inflorescence per flowering season and by having a perianth that is distinctly flared at the mouth, with especially the external, apical ⅓ of the perianth conspicuously yellow.

Abstract We analysed the genetic divergence and morphology of the aedeagus (i.e. phallobase and parameres) in Canthon cyanellus at different geographical levels. The results from both approaches were compared with the current taxonomic assignment of the C. cyanellus complex, which includes three subspecies. We found a high variation in all the morphological characters of the aedeagus in the populations analysed; the morphometric variation was not geographically structured, either by population or by region. The genealogical analysis indicates a significant genetic structure that does not match either the morphological variation in the male genitalia or the previous subspecific taxonomic classification. Our results suggest that the morphological variation of the aedeagus is seemingly not an isolating reproductive barrier and that the intra- and interpopulation morphological variability of the aedeagus in the C. cyanellus complex does not permit the division into several species. We suggest that other evolutionary forces, such as genetic drift and sexual selection, have influenced the evolution of the male genitalia and the incipient differentiation of this species complex.

All species ofDesmoxytess.s. seem to be endemic to continental Southeast Asia (except the ‘tramp’ speciesD.planata). Some biological observations (relationship with mites, moulting) are recorded for the first time. Complete illustrations of external morphological characters, an identification key, and distribution maps of all species are provided.

The region of Lagoa Santa, Minas Gerais, Brazil, is one of the most important karstic areas of the Brazilian Quaternary due to the faunistic diversity of living and extinct forms. Among them, some taxa remain poorly studied, as is the case of Calomys anoblepas Winge 1887. Despite the recent allocation of the taxon within Juliomys, its description and morphological analysis are condensed, based on comparative few specimens and on few informative characters. In this study, we investigate characters proposed to distinguish species of Juliomys, and reevaluate the taxonomic status of the fossil Juliomys anoblepas. We analyzed 80 cranio-dental morphological characters in 233 specimens represented by the four species currently recognized: J. pictipes (Osgood 1933), J. rimofrons Oliveira & Bonvicino 2002, J. ossitenuis Costa, Pavan, Leite & Fagundes 2007, and J. ximenezi Christoff, Vieira, Oliveira, Gonçalves, Valiati & Tomasi 2016. We also performed principal component analysis on eight craniodental measurements available for the J. anoblepas hypodigm. The review of morphological systems and the evaluation of the characters used in the literature revealed that there are no diagnostic characters in the anterior portion of the skull and in the molar series of Juliomys, being difficult to differentiate the fossil from the other living species. Only six qualitative characters were variable and applicable to the hypodigm of J. anoblepas. Characters are polymorphic, invariable, or the fossil is not sufficiently complete to determinate its states. The taxon could not be morphometrically differentiated from J. pictipes and J. ossitenuis. Based on the results presented herein, we consider J. anoblepas as a nomen dubium and restrict its name to the taxon’s hypodigm.

Two New Species

We describe two new species of green pitviper from Southeast Asia that are morphologically similar to Cryptelytrops macrops, but can be distinguished from that species by genetic means, multivariate analysis of morphology and some aspects of coloration. Cryptelytrops cardamomensis sp. nov., is described from southeastern Thailand and the Cardamom Mountains of southwestern Cambodia. Cryptelytrops rubeus sp. nov. has been recorded from southern Vietnam and eastern Cambodia. These species have previously been confused with C. macrops, hence we also present here a redescription of this species, whose range is now restricted to Thailand, southern and central Laos, and northeastern Cambodia. All three species are present in Cambodia, but have disjunct ranges corresponding to three separate highland regions in southwestern (Cardamom Mountains), northeastern (western edge of the Kontum Plateau) and eastern (low elevation hills on the western edge of the Langbian Plateau) Cambodia for C. cardamomensis, C. macrops and C. rubeus respectively. However, there is still considerable morphological variation between geographically separated populations of C. macrops s.s., and greater sampling in southern and northern Thailand in particular may be required before the species diversity of this group is fully clarified.

Two new species of nereidids, Dendronereis chipolini n. sp. and Neanthes hsinchuensis n. sp., collected from brackish aquaculture ponds near coasts of southern Taiwan and fouling community on docks of the Hsinchu fishing port in northwestern Taiwan, respectively, are described in the present study. Dendronereis chipolini n. sp. differs from its congeners by a combination of number and morphology of branchiae, morphology of neuropodia and form of neuropodial homogomph spinigers. Neanthes hsinchuensis n. sp. can be distinguished from congeners reported from East and Southeast Asia by a combination of numbers of conical paragnaths, morphology of notopodia, the absent/present of prechaetal lobe and forms of neuropodial chaetae. A key to Dendronereis species of the world is included, together with a table of morphological characters of Neanthes species reported from East and Southeast Asia, which have no conical paragnaths on Area V of the pharynx.
