A New Species

A new species of the gekkonid genus Cnemaspis is described based on a series of nine specimens from near Sankari in Salem district, Tamil Nadu state, southern India. The new species is diagnosable by the following suite of characters: a small-sized Cnemaspis (adult snout to vent length less than 33 mm); heterogeneous dorsal pholidosis consisting of weakly keeled granular scales intermixed with large strongly keeled, conical tubercles, 9–11 rows of dorsal tubercles, 12–17 tubercles in paravertebral rows; spine-like scales absent on flank, 17–20 lamellae under digit IV of pes. Males with 4–6 femoral pores on each thigh, separated on either side by eight poreless scales from four precloacal pores; precloacal pores separated medially by a single poreless scale; two single dorsal ocelli on occiput and between forelimb insertions, two pairs of ocelli on either side just anterior and posterior to forelimb insertions. Cnemaspis agarwali sp. nov. is the fifth endemic species of Cnemaspis from peninsular India outside the Western Ghats and highlights the rich and unique diversity of this understudied region.

Abstract During the last two decades of intensive botanical survey of the tropical dry evergreen forest, a total of 82 endemic taxa were found out of 1142 species enumerated from 85 sites in the three Coromandel Coastal districts of the state Tamil Nadu: Cuddalore, Kancheepurm and Villupuram, and in the Pondicherry district. Of 82 species, 17 are trees, 11 shrubs, 9 climbers and 45 herbs. Distribution of these endemic species was analyzed and categorised as endemic to the country, peninsular India, southern India, Eastern and Western Ghats, and at the state and district level. Interestingly, the study found that some endemic species were disjunctly distributed between districts, states, ghats, climatic regimes and bioregions. Anthropogenic disturbance and species threat status were also studied and discussed.

Strobilanthes lawsonii was described by Gamble based on a collection made from Sispara Ghat of Nilgiri District, Tamil Nadu.  Later researchers reported its distribution in Kerala, and S. gamblei and S. pushpangadanii, two endemic species of the Western Ghats, were synonymised with S. lawsonii during the genus revision in southern India in 2006.  During a recent expedition to Muthikulam forest of Palakkad, Kerala the authors collected typical S. lawsonii.  After comparing the new collections with S. gamblei and S. pushpangadanii, it was found that both taxa are distinct from S. lawsonii, with the most notable morphological differences being partially fused corolla lobes and exserted stamens.  A detailed comparison of the three taxa is provided here, along with color photographs and a taxonomic key for easy species identification.

Intensive botanical survey was done more than two decades on Tropical Dry Evergreen Forest from four coastal districts viz. Cuddalore, Kancheepurm, Nagai and Villupuram of Tamil Nadu and Union Territory of Pondicherry. A total of 87 protected (hillocks, reserve forest) and unprotected (sacred groves, unclassified vegetation) sites were regularly studied from five districts. From this study 82 endemic taxa were enumerated. In addition 25 endemic species were added for the analysis through literature screening and herbarium consultation from 10 Coromandel coastal districts of Tamil Nadu. In all 107 species were recorded, among them 19 are trees, 18 shrubs, 9 climbers and 61 herbs. Distribution of these endemic species were analysed and categorised into endemic to the country, peninsular India, southern India, Eastern and Western Ghats, state and district level. Interestingly the study found that some endemic species were disjunctly distributed in between districts, states, ghats, climatic regimes and bioregions. The disturbance, threat status and conservation measures of few endemic and IUCN red listed species were also studied and discussed.

Scientific Name

Due to the presence of antibiotic or antiseptic nature’s chemicals, plants are remarkable for the treatment of wounds. Having this fact as research theme, the present study was carried out to document the therapeutic uses of medicinal plants used to heal wound in Karandamalai of Dindigul district in Tamil Nadu. The frequent fieldwork was conducted from October 2019 to January 2020 for this study. The scientific name, family name, local name (in Tamil), part(s) used, mode of preparation, and mode of administration of medicine were recorded. A total of 24 medicinal remedies prepared from 24 plants were recorded. Further research on the phytochemistry and pharmacology of these medicinal plants should be conducted. Keywords: Medicinal plants, Wound healing, Karandamalai, Dindigul district, Tamil Nadu.
