Indobanalia thyrsiflora is an endemic species occurring in peninsular India (Andhra Pradesh, Karnataka, Kerala and Tamil Nadu States) and Sri Lanka. A nomenclatural study of the basionym Banalia thyrsiflora, published by Moquin-Tandon in Candolle’s Prodromus (year 1849), is carried out and the name is lectotypified on a specimen deposited at P (barcode P00609924); isolectotypes are traced at K and CAL. A preliminary morphological characterization of the species is also given, based on field surveys and examination of herbarium specimens. We noted that I. thyrsiflora is highly variable. However, we prefer to avoid, for the moment, taxonomic conclusions about the various morphotypes found, waiting the complete results of this ongoing morphological and molecular investigations.

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.

Horabagrus brachysoma, thought to be endemic to the southern parts of the Western Ghats of India, is recorded for the northern parts of the Western Ghats, extending the species distribution range by 180 km. We have confirmed the identity of the species and the fact that the species is indigenous to this area and not an artifact of recent introductions using molecular methods. Apart from the range extension we have also provided detailed analysis regarding the nature of morphometric variations between the sexes, length-weight relationship, and a brief discussion about the potential habitat requirements and threats to this species. By documenting the possible threats to this threatened and endemic species, we have commented on the possible measures to conserve the species in the wild.

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.

Original Vegetation

Humans have altered the forests of urban regions drastically, thereby reducing the original forests to isolated fragments. Such fragments may contain remnants of the original vegetation. Nanmangalam Reserve Forest (NRF), located in the Metropolitan Chennai, Tamil Nadu, India, is an example of such a forest fragment, covering an area of 321 ha. A total of 449 angiosperm species belonging to 313 genera representing 83 families were recorded from NRF. Amongst the species, 79% were dicots and 21% were monocots. The most genera/species rich families were Fabaceae (37/69) and Poaceae (34/52). The species rich genera included Cassia (10), Crotalaria (7), Erogrostis, Hedyotis and Phyllanthus (6 each). Six endemic species were recorded. This diversity amidst a rapidly expanding city has to be protected in order to enable the conservation agenda of urban areas.
