“…3 The family Verbenaceae is closely related to Lamiaceae and differentiated mainly on the basis of terminal (Verbenceae)/gynobasis (Lamiaceae) style with difficulties in separating members of one family from the other. 58 Previously, several genera from Verbenaceae were transferred to Lamiaceae including Tectona 2 , 59 but the systematic position of genus Tectona still lacks clarity. Out of 236 genera of Lamiaceae, 226 were placed under seven subfamilies (Ajugoideae, Lamioideae, Nepetoideae, Prostantheroideae, Scutellarioideae, Symphorematoideae and Viticoideae) and 10 genera were listed as Incertae sedis 3 (of ‘uncertain placement’) by considering morphology, secondary metabolites and molecular phylogeny.…”

Teak (Tectona grandis L. f.) is one of the precious bench mark tropical hardwood having qualities of durability, strength and visual pleasantries. Natural teak populations harbour a variety of characteristics that determine their economic, ecological and environmental importance. Sequencing of whole nuclear genome of teak provides a platform for functional analyses and development of genomic tools in applied tree improvement. A draft genome of 317 Mb was assembled at 151× coverage and annotated 36, 172 protein-coding genes. Approximately about 11.18% of the genome was repetitive. Microsatellites or simple sequence repeats (SSRs) are undoubtedly the most informative markers in genotyping, genetics and applied breeding applications. We generated 182,712 SSRs at the whole genome level, of which, 170,574 perfect SSRs were found; 16,252 perfect SSRs showed in silico polymorphisms across six genotypes suggesting their promising use in genetic conservation and tree improvement programmes. Genomic SSR markers developed in this study have high potential in advancing conservation and management of teak genetic resources. Phylogenetic studies confirmed the taxonomic position of the genus Tectona within the family Lamiaceae. Interestingly, estimation of divergence time inferred that the Miocene origin of the Tectona genus to be around 21.4508 million years ago.

“…All four species share similar habit with slender, sturdy and erect stems and long drooping leaves. However, they differ from each other by their floral characters viz., corolla colour, ornamentation, indumentum and corona structure and thus hold their specific identities (Prasad and Rao, 2013;Prasad and Venu, 2018;Pullaiah et al, 2019;Rasingam et al, 2013;Sadasivaiah et al, 2016).…”

During the verification of nomenclature in connection with the preparation of ‗Supplement to Florae Indicae Enumeratio' and ‗Flora of Tamil Nadu', the authors came across a number of names that need to be updated in accordance with the changing generic concepts. Accordingly the required new names and new combinations are proposed here for the 50 taxa belonging to 17 families. Ke ywo rdsCombination novum Indian flora Nomen novum Tamil Nadu an angle just below the flower (Karuppusamy et al., 2013;Meve and Liede, 2002; POWO, 2019). When Caralluma geniculata (Gravely & Mayur.) Meve & Liede is transferred to Ceropegia, the epithet is occupied by Dyer's 1979 name. Thus a new name is required, and is proposed here.

The identity of Ceropegia hirsuta in Thailand has been questioned. Although this plant is quite similar to the original C. hirsuta from India, being entirely hirsute, with yellowishshaded flowers, a curved, funnel-shaped corolla tube, and broad corolla lobes shorter than the corolla tube, there are several clear differences in morphological traits between the materials collected in Thailand and the type and further specimens collected in India. Moreover, C. hirsuta s.s. is restricted to Peninsular India. In this study, using molecular phylogenetic analysis based on DNA sequence data for ITS (nuclear) and trnT-L, trnL, and trnL-F (all cpDNA) markers, and classical morphology-based delineation, we demonstrate that the plant from Thailand represents a species on its own clearly separated from C. hirsuta s.s. as well as from all other known congeners. Therefore, we here describe it as a new species, C. citrina.A detailed description, illustrations, and photographs are provided, together with a comparison of morphological traits of C. citrina, C. hirsuta and another Thai species, C. foetidiflora. We also provide characterization of floral volatile compounds and pollinators.Our study emphasizes that morphological convergence may lead to errors in taxonomic treatment within the genus Ceropegia, and that phylogenetic relationships are largely congruent with geographic distribution.
