Investigated the distribution of climber and its conservation status in tropical forests of Courtallam hills in southern Western Ghats of Tamil Nadu, India during 2017-2018. A total of five 1 ha plots were established, and all climber species ≥1 cm diameter at breast height (dbh) were counted, which resulted in a total of 81 climbing plant species that representing to 62 genera under 30 families. Study plots revealed the most abundant climber species are Jasminum flexile (Oleaceae), Salacia oblonga (Celastraceae) and Ziziphus oenopolia (Rhamnaceae). The dominant climber species families in the study plots include Apocynaceae (11 species), Leguminosae (10 species), Menispermaceae and Vitaceae (6 species each), Capparaceae and Oleaceae (5 species each) and Convolvulaceae (4 species). Among 81 climber species, about 12 species are documented as threatened species of Courtallam hills. The results of this investigation suggest that forest management and forest protection is important for in-situ conservation of liana diversity with the involvement of local community.

A New Species

A new species, Artabotrys sericeus Sujana & Vadhyar, is described from Tamil Nadu, India. The new species shows some resemblance to Artabotrys zeylanicus Hook.f. & Thomson, but it can be easily distinguished by the shape, size, colour and indumentum of the petals as well as the shape and texture of the monocarps. Illustrations, photographs and SEM images of the pollen grains of the new species are provided. The conservation status of the new species is also assessed.

A new species of Striga from Tamil Nadu parts of Western Ghats of India is described and illustrated as Striga kamalii sp. nov. The new species shows similarity with S. densiflora in having a densely hispid stem, linear leaves, bracts longer than calyx, and oblong fruit shorter than calyx lobes, but differs in the 10-ribbed calyx, the glandular hairs on calyx and corolla tube, and the obovate-rounded petals. A detailed description, with data on distribution and parasitism together with relevant taxonomic notes and colour photographs are provided.

Diameter Classes

Tropical forests have long been accepted for their productivity and ecosystem services on account of their high diversity and stand structural attributes. In spite of their significance, tropical forests, and especially those of Asia, remain understudied. Until recently, most forest inventories in Asia have concentrated on trees 10 cm in diameter. Floristic composition, plant species diversity, above-ground biomass, basal area, and diversity were investigated across different life forms and two-diameter classes in a large-scale 10-ha plot, in the undisturbed tropical seasonal rain forest of Southern Western Ghats, Kerala, India. The regeneration pattern of the study area was examined by evaluating fisher's alpha and IVI (Important Value Index) across three layers of vegetation (seedling, sapling, and tree). Within the plot, we recorded 25,390 woody plant species ≥1 cm dbh from 45 families, 91 genera, and 106 species. Plant density was 2539 woody individuals per hectare, with a basal area of 47.72 m2/ha and above-ground biomass of 421.77 Mg/ha. By basal area, density, and frequency, the Rubiaceae, Sapotaceae, and Malvaceae families were the most important. Small-diameter trees (1 cm ≤ dbh ≤10 cm) were found to be 78 percent of the total tree population, 20.2 percent of the basal area, and 1.4 percent of the aboveground biomass. They also possessed 6 percent more diversity at the family level, 10% more diversity at the genus level, and 12% more diversity at the species level than woody individuals under 10 cm dbh. Woody individuals of treelets life form and small-diameter classes were much more diverse and dense than the other groups, indicating that results based only on larger canopy trees and larger diameter class maybe not be an appropriate representation of the diversity status of a particular tropical forest type. The lower density of individuals in the initial girth class indicates the vulnerability of the forest system to anthropogenic, natural disturbance and a changing climate. Reduce the minimum diameter limit down to 1 cm, in contrast to 10 cm limit used in most of the evergreen forest inventories, revealed a high density and diversity in the lower stories.

An extensive survey and population analysis of the endemic and endangered tree Kingiodendron pinnatum, was carried out in the Kerala area of the Western Ghats. The aim was to assess the pattern of distribution, population size and natural regeneration of the species. The fragmented and patchy populations of the species are distributed in evergreen/semi evergreen habitats within an altitudinal range of 176-680m elevation. The tree attained a first layer/canopy species with a height range from 24–30m. Altogether 17 populations were identified and mapped in 13 forest locations in the region.  A total of 140 adult individuals of the species were enumerated within the 13 forest locations. Natural regeneration of the species recorded from three zones among the 13 forest locations covering 21,000m2 area representing the Kerala state.  The flowering trees displayed a height and dbh range of 10-30m and 85-320cm, respectively. The individuals are spatially arranged in aggregation among patchy populations. The populations are well represented by reproductive individuals with 77% and pre reproductive with 23%. Seedlings of 35.9% attained a height below 1m and 64.01% of a height above 1m. Considering the extent of distribution in the state, increase in the number of mature individuals (in addition to the enumerated area), and fair count of seedlings suggests a healthier conservation status of the species in the region. The economic and medicinal values, occurrence of isolated and fragmented populations, irregularities in the flowering and fruiting period among populations, however, extends urgent concerns over the pollination biology, detection of diverse genotypes subsequent multiplication and restoration of dwindling populations for the effective conservation and management of the species in situ.
