<p><em>Nepeta</em> L. is one of the most important genera of the <em>Lamiaceae</em> family, which widely distributed all over the word. The members of this genus are use of traditional and modern medicine. <em>Nepeta </em>species growth naturally in various parts of Iran and recent years the number of its species is increasing. In the study, morphological characteristics of twenty four populations of seventeen <em>Nepeta</em> taxa were used for infra-generic classifications, because there were many discussions about infra-generic classification of this genus. For this, forty qualitative as well as quantitative morphological features of both vegetative and reproductive organs were examined. Data were analyses with MVSP and SPSS softwares. ANOVA test showed significant variations for all the studied quantitative traits, with the exception of flower number per cycle. Furthermore, most of qualitative characters such as basal and floral leaf shape and petal color differed between taxa. PCA-biplot and CA joint plot showed that some morphological characters had taxonomic value and were useful in identifications of species. In many cases, clustering of species in the UPGMA tree, PCA and PCO plots did not confirm species placements in groups/ sections according to modern classifications. Furthermore, populations of same species did not cluster closely. It seems that ecological conditions had strong effect on different features of this study and high infra-specific variations were found among the studied species. </p>

Pyrus Pyraster

&nbsp;A population of 1,149 pear individuals from Slovakia is analysed according to their morphological characteristics of fruits and leaves. Three basic taxa were identified &ndash; Pyrus pyraster, Pyrus amphigenea and Pyrus nivalis. Qualitative traits (shape of leaf blade, fruit shape, type of leaf or fruit base, etc.) allowed the exact identification of a particular taxon only in some cases. Quantitative characteristics of leaves proved to be more suitable for the identification of analysed taxa. Statistically significant differences were found between all studied taxa in the values of leaf length and width, and also in the values of relative characteristics that described the leaf shape. Exceptionally the length of leaf petiole had very variable values (S<sub>x</sub><sub>% </sub>= 25.70&ndash;29.75%), therefore it was impossible to classify the species according to this character. Generally, fruit shapes and dimensions are less representative for taxonomy use although significant differences between all studied taxa were found in the values of fruit length. The correct taxonomic classification of pears cannot be done according to one characteristic. It is important to consider a few of them (shape and length of leaf blade or its slenderness, shape quotients and also the shape and length of fruits) for the appropriate classification of pear individuals. &nbsp; &nbsp;

Biodiversitas 22: 2853-2859. Marsilea is a hydrophyte fern that has plasticity often influenced by enviroment. Several of the species with different habitats or geographies show morphological variations. Therefore, this study aims to analyze the variations in morphological characters of M. crenata growing in aquatic and terrestrial habitats. A total of 38 plant samples were collected from their natural habitats including floating aquatic, emergent aquatic, and terrestrial types. Morphological variations data included 4 qualitative characters and 9 quantitative characters. The quantitative characters were analyzed by one-way ANOVA to test for differences, while the combination of both characters was analyzed using Principal Component Analysis (PCA) to determine the distribution between groups. The data results showed a separate grouping pattern between aquatic and terrestrial populations. These two groups showed significant differences in 5 quantitative characters and 2 qualitative characters. However, emergent aquatic samples’ distribution pattern is closer to the terrestrial group. The characters’ similarity of these two populations was in ??the rhizomes air spaces area, the position between leaflets and absence of red streak on the abaxial lamina. Conclusively, the variations in M. crenata’s morphological characters indicate that this plant has experienced morphological adaptations to water availability in its environment.

Ginseng plant (Phytolacca octandra L.) is a wild plant that has the potential to be used as medicine. The morphological characteristics of ginseng plants in Indonesia are different. Therefore, it is necessary to carry out research aimed at characterizing the morphology and phytochemical screening of ginseng (P. octandra L.) leaves and tubers. The research was conducted first by observing morphological characters and screening phytochemical compounds such as alkaloid test, flavonoid test, phenol test, tannin test, saponin test, terpenoid test, and steroid test. The results of the research on the morphological characterization of ginseng (P. octandra L.) were: having a taproot which was modified into a tuber, a round, smooth, red color, pointed leaf shape, the base and tip of the leaf were pointed, buni fruit type, round flat, colored blackish-purple when ripe, a compound flower is located at the end of the branch and has flat, round seeds. Ginseng tubers have triterpenoid and saponin compounds, while the leaves only have saponin compounds. The potential development of ginseng (P. octandra L.) is currently limited as traditional medicine by local people. This is due to limited knowledge in its development efforts and unknown phytochemical content.

Abstract. Nikmah IA, Rugayah R, Chikmawati T. 2021. Morphological and genetic variation in populations of Desmos chinensis Lour. (Annonaceae). Biodiversitas 22: 811-822. Desmos chinensis is a woody climber or scandent shrub genus in Annonaceae that has moniliform fruits. Desmos chinensis Lour. can be found throughout Southeast Asia. This species is widely used as a traditional medicine in several countries in Asia, however, the information on its morphological and genetic variation has never been reported. The objective of this study was to reveal the genetic variation of Desmos chinensis on Java island (Indonesia) based on the morphological characters and Inter-Simple Sequence Repeats (ISSR) markers. Leaf samples were collected by exploring seven regions in Java island. Variation in morphological characteristics were described and discussed in detail. Genetic variation was assessed using the ISSR marker. The morphological characteristics of D. chinensis in Java varies in habit; leaf shape, leaf size, leaf color; flower position, flower reflexity, pedicel bract position, number of petals, petal color, petal shape, petal apex, undulation of petal; and number of monocarp per fruit. A total of 53 samples collected from seven populations were screened by 25 ISSR primers, wherein 11 primers produced 47 clear and reproducible bands covering 85.1% of polymorphic bands. Desmos chinensis in Java were divided into five natural populations. Furthermore, the mean value of the Shannon index and genetic diversity index were 0.223 and 0.151, respectively. Moreover, the variations within and among populations examined using AMOVA showed the occurrence of 38% of total genetic variations among the different populations, therefore, the remaining 62% was due to variations within the population. Morphological and genetic variations are important preliminary information for determining the conservation strategy of Desmos chinensis.

Acacia Sieberiana

Acacia belongs to the family fabaceae among the largest legume genera consisting of eighteen species with the majority of the species distributed in tropical and sub-tropical Africa. Classification of Acacia have remained a daunting task due to it wide spread and also hampered by is large number of species ,prevalence of morphological convergence. Morphological variations in foliar, thorn, inflorescence of some Acacia species found in Zaria for their taxonomic identification at species level were evaluated were Seven species and one variety of Acacia were taxonomically classified using morphological characters. In almost the species leaves were compound bipinnate, alternate and pinnulesare oblong. However the pinnules of A. senegal are obovate. In A. auriculiformis the leaves are simple and sickle-like in shape. Leaves texture ranges from glabrous to pubescent and leaf margin were entire in all the species. The morphological measurement parameters were analyzed using ANOVA cooperation and the results indicate variations among the species. The variations observed in some of the characters could be of taxonomic importance in the identification of the species. Overall ranking indicated that Acacia sieberiana var  sieberiana and Acacia sieberiana var villosa were the best with high values of morphological characters of pinna length (3.50±0.11 cm and 3.82±0.16 cm respectively) and number of pinna (18.80±1.32 and 41.70±1.52 respectively). The high values of pinna could be used in solving taxonomic problems associated with Acacia species and in mapping out breeding strategies for the production of cultivars with better foliar yield of Acacia species in Nigeria

The Individual

In the course of a program to create chromosome addition lines in cotton, offspring obtained by selfing a plant carrying the 52 chromosomes of the normal complement of Gossypium hirsutum L. and two different chromosomes from Gossy pium stocksii Mast, were studied. Observations were made on the karyology, morphology and fertility of the individual plants comprising this population. The various karyological classes encountered were interpreted on the basis of a random distribution of the two stocksii chromosomes of the female plant, which have practically no affinity with the hirsutum genome. The karyological classification of the population was determined by analysing the variation of some morphological characters (leaf shape, lint color). The fact that both stocksii chromosomes exert specific effects on the phenotype of plants inheriting them showed that they can be perpetuated in the nucleo-cytoplasmic complex of G. hirsutum, while retaining at least certain of their genetic activities. Their action and interaction, superimposed on the functions of the hirsutum genome, lead to the expression of new characters accompanied by a decrease in vigor and fertility. This duality is characteristic of the disomic addition types, which besides are afflicted with karyological instabilities. The alien addition types which can be obtained by crossing G. hirsutum with widely related diploid species have therefore no immediate agronomic value, but they may constitute a starting point for new investigations.

The genus Selaginella, commonly referred to as spikemosses, is an important component of the Philippines’ lycophytes diversity. Mountain ecosystems in Mindanao island hold diverse species of lycophytes, however the morpho-taxonomy diversity of this group is poorly documented there. The study aimed to determine Selaginella species richness, distribution and phenetic relationships based on morphological characteristics in Mindanao island. Specimens of Selaginella were collected in Mt. Apo, Kidapawan City; Mt. Hamiguitan, Davao Oriental; Mt. Kiamo, Mt. Kitanglad, Mt. Musuan and Mt. Limbawon in Bukidnon; Mt. Timpoong, Camiguin; and Mt. Malindang, Misamis Occidental. The 24 Selaginella species were collected and subjected to numerical phenetic analysis using the PC-ORD program. A total of 11 morphological characters and 44 character states were used in the analyses. Of the 24 species, seven are Philippine endemics, four are potential new species and two species are widely distributed in the areas studied. Results of the phenetic analysis showed four major clusters.

Abstract The European ground cherry (Prunus fruticosa Pall.) as a potential dwarfing rootstock attracted the attention of cherry rootstock researchers in several breeding projects. In order to clarify some doubtful classification of collected and promising specimen of supposed hybrids, we compared morphological characteristics to literature data. Genetic analysis was also undertaken using simple-sequence repeat markers. Our results suggest that the investigated P. fruticosa forma fruticosa specimens are tetraploid and the genetic analysis did not contribute to distinguish the P. fruticosa forma fruticosa and forma aucta. Based on morphological characters, we identified few specimens of spontaneous hybrid P. fruticosa × P. mahaleb (P. × jávorkae). Our genetic analysis supports the hypothesis that the sample shrub is triploid and show genetic relationship with P. mahaleb. This triploid hybrid due to the flower sterility represents a blind alley in its evolution. We identified from each investigated habitat specimens of supposed hybrid derivatives of ground cherry P. fruticosa × P. avium (P. × mohácsyana). This hybrid clearly showed distinct morphological characteristics, easily distinguishable from the P. fruticosa f. fruticosa and f. aucta and the genetic analysis suggests that the accessions are triploid. The flower sterility limits the usage of this hybrid derivative for further cross-breeding but allows usage as clonal cherry rootstock. Our genetic analysis suggests that samples of P. × eminens are tetraploid, fertile hybrid derivative of ground cherry occurring in some habitats of the basic species and show similar morphological characters to the cultivated sour cherry.
