Rechinger, in his 1968 Flora Iranica account, considered Sterigmostemum to contain nine species in Iran. In 1980 Léonard excluded S. purpurascens from Sterigmostemum and transferred it to the new genus Petiniotia as P. purpurascens. Subsequently, in 1988 Jacquemoud retained this species in Sterigmostemum, but as subgenus Petiniotia. In 2000 Sonboli et al. excluded S. laevicaule from Sterigmostemum and considered it to be a synonym of Erysimum crassicaule. Phenetic analysis of morphological and anatomical characters from herbarium and fresh specimens supports the recognition of five species in Sterigmostemum (S. incanum, S. sulphureum, S. acanthocarpum, S. ramosissimum and S. longistylum). The results of cluster analysis and ordination based on these characters confirm Léonard's exclusion of S. purpurascens and transfer to the genus Petiniotia as P. purpurascens. A key is provided to distinguish Petiniotia from Sterigmostemum, followed by descriptions of the two genera and a conspectus of species.

Abstract. Sungkawati M, Hidayati L, Daryono BS, Purnomo. 2019. Phenetic analysis of Curcuma spp. in Yogyakarta, Indonesia based on morphological and anatomical characters. Biodiversitas 20: 2340-2347. Curcuma spp., also known as ginger (Zingiberaceae), has economic value in traditional medicine. However, its many morphological variations cause difficulties in identification and classification. Therefore, observation of its morphological and anatomical characteristics, and of the phenetic relationships between Curcuma species, is important. This research aims to determine the specific characteristics of Curcuma spp. and to examine its phenetic relationships based on morphological and anatomical characteristics. The research was conducted in July 2018-February 2019 in the Bantul, Gunungkidul, Sleman and Karanganyar regions. Observation of the anatomical characteristics was conducted on the leaves and rhizomes and the data analyzed according to descriptive and quantitative/numerical methods. Clustering analysis with the Gower General Similarity Coefficient and Principal Component Analysis (PCA) was performed to determine the role of each character in groupings. The results of the research found seven species from 23 OTUs observed (C. aeruginosa, C. domestica, C. manga and C. xanthorrhiza, each with four OTUs; C. soloensis and C. zedoaria, with three OTUs each; and C. heyneana with one OTU) and showed that specific morphological characteristics were found in the flesh color rhizome, pseudostem color and midrib color. Specific anatomical characteristics were evident in the secretion cell color and the presence of trichomes on the leaves and rhizomes. The dendrogram shows a 0.70 phenon line consisting of two groups, group A (C. soloensis and C. domestica) fused in a 0.760 similarity index, and group B (C. aeruginosa, C. mangga, C. heyneana, C. soloensis, C. xanthorrhiza and C. zedoaria) fused in a 0.654 similarity index, which means that C. soloensis and C. domestica have a close phenetic relationship. The 0.80 phenon line consisted of five groups: C. domestica, C. soloensis, C. xanthorrhiza, C. zedoaria-C. mangga-C. heyneana and C. aeruginosa.

Archaeologically defined inter-group differences in the Northeast subarea ate assessed with a phenetic analysis of published craniometric information. Spatial distinctions in the material culture are in good agreement with those defined by the cranial metrics. The fundamental dichotomy, between the Ontario Iroquois and the eastern grouping of New York and New England, suggests a long-term dissociation between these two groups relative to their ecologic adaptations, trade relationships, trait-list associations, and natural and cultural barriers to gene flow.

Morphological Relationship

Euphorbiaceae is one of the largest family of flowering plants, in our study different species were collected from different localities of Mizoram, the collected specimens were studied and their morphological features noted. 34 genera of Euphorbiaceae s.l were used in the study. Cladistic analysis was performed in Mesquite software and Phenetic analysis was done in NTsys software. Both analyses produce a pictorial representation in a form of a tree; cladistic analysis produce phylogenetic tree (evolutionary relationship) while phenetic analysis produce phenogram (morphological relationship). The results of the aforementioned analyses were further analysed by total evidence technique and taxonomic congruence, a phylogenetic software PAUP is used for this purpose. The resultant trees were very different and comparison was done to find correlation between evolution and morphological characters. The research finds various correlation among characters like the number of locule in ovule, phyllanthoid branching and support the inclusion of genus like Breynia, Sauropus into Phyllanthus.

Phenetic analysis of all the black pepper cultivars in Malaysia is crucial to determine the morphological difference among them. The objective of this study is to ascertain the morphological distinctness and interrelationships among the cultivars to ensure registration of each variety under the Plant Variety Protection Act, as a prerequisite toward implementation of a monovarietal farm policy in the future. Cluster analysis revealed that cultivars “Semongok Aman” and “Semongok 1” have high distinctness values for identification; thus, varietal diagnosis for the two cultivars is easy. Cultivars “Nyerigai,” “India,” “Semongok Perak,” and “Semongok Emas” were grouped in the most diverse clusters among the ten cultivars studied. The four cultivars have a similarity index as high as 92%; however, investigation of leaf width, leaf width-length ratio, seed weight, and conversion rate (fresh to black pepper) gives the ability to determine the characteristic differences. Cultivars “Lampung Daun Lebar” and “Yong Petai” have a similarity of 96%; however, the two showed distinctive differences in leaf width, leaf length-width ratio, spike thickness, and spike length characteristics. On the contrary, cultivars “Kuching” and “Sarikei” showed the highest similarity index, at 98%, and thus are among the most difficult cultivars to diagnose the morphological difference. However, the principle component analysis showed that the fruit size and seed diameter were the important diagnostic key characteristics. Overall, the leaf width, leaf width-length ratio, fruit spike, and conversion rate characteristics are among the key characteristics to differentiate among cultivars of black pepper in Malaysia. At the same time, the principle component analysis carried out has enlightened some interrelationships on the morphological characteristics between cultivars. This information is crucial for the future of the plant varietal improvement program in Malaysia.

The purpose of this research was to evaluate the growth phase of orchid Vanda hybrid (Vanda limbata Blume X Vanda tricolor Lindl. var. suavis) response with colchicines treatment, to determine precise effective concentration of colchicines and duration of treatment to induce polyploidy. This research used variation of colchicines concentration which were 0.01%; 0.05%; 0.1%; 0.5%; 1% and 0% and incubation for 6 hours; 12 hours; 18 hours; 24 hours; and  4 days. Treatment was done in aseptic condition using protocorm aged 7 week after sowing. After treatments, plants were planted on Vacint and Went (VW) medium supplemented with of 150 ml/l coconut water. After four months, they were subcultured in medium VW + 150 ml/l + 150g/l banana extract. The results showed that the orchid Vanda hybrid was intolerant to colchicine concentration of 0.1; 0.5 and 1% by death protocorm was more than 50%. Concentration of 0,5% with 6 hours soaking time is the most effective to induced tetraploid in orchid Vanda hybrid. Morphological characters of tetraploid plantlets had lower average number and length of roots, the number, length, and width of the leaves than those of control. Anatomical characters of the tetraploid plantlets revealed the highest stomatal size and had smaller of stomatal index than controls. This evident indicated a negative correlation between stomatal index and ploidy level. Cytological analysis with flow cytometry revealed that tetraploid plantlets (2n=4x=76) stained with DAPI showed the chromosome number more than those of control (2n=2x=38).Key words      : polyploidization, colchicine, vanda orchid, chromosome number
