Distribution and habitat associations of the Critically Endangered frog Walkerana phrynoderma (Anura: Ranixalidae), with an assessment of potential threats, abundance, and morphology. Little is known about Walkerana phrynoderma, a frog endemic to the Anamalai Hills of the Western Ghats of India. Baseline information (i.e., distribution, threats, habitat characteristics, activity patterns, and relative abundance) is provided for this species, with the aim of improving our understanding of the status of the species in the wild. Visual-encounter, transect, and time-activity budget surveys were conducted in and around the Anamalai Hills of the Western Ghats. The frog skin was swabbed to determine the presence/absence of Batrachochytrium dendrobatidis, and habitat and environmental characteristics were recorded at sites where W. phrynoderma was found. These data were compared with those of sites apparently lacking this species that had suitable habitat. Walkerana phrynoderma is restricted to evergreen forests between 1300 and 1700 m a.s.l. in the Anamalai Tiger Reserve and at Munnar; thus, its range was extended from the state of Tamil Nadu to the adjoining state of Kerala. Pesticide runoff and human disturbance are the most severe threats to the species; B. dendrobatidis was not detected. This nocturnal anuran prefers forest edges and is associated with well-shaded forest foors in cool areas near freshwater streams. Walkerana phrynoderma is rarely encountered whereas its congener, W. leptodactyla, is more common. The impact of anthropogenic disturbances, especially waste disposal and development of tourism infrastructure, should be evaluated. The land that is owned by the Forest Department peripheral to the protected areas could be designated as eco-sensitive sites to prevent changes in land use that could have an adverse effect on W. phrynoderma.

A New Species

Impatiens megamalayana, a new species from Tamil Nadu, India is described and illustrated. This species is characterized by a ridged stem, ensiform and villous leaves, a wrinkled boat-shaped lower sepal with outwardly curved tip, ornamented seeds and strictly ovate pollen grains. This combination of characters makes determining the relationships of I. megamalayana difficult. The floral structure of I. megamalayana is closely allied to I. herbicola Hook.f. and I. inconspicua Benth. in Wall., the latter with three varieties, but it differs by several unique vegetative and floral features. Impatiens megamalayana is assessed as Critically Endangered in accordance with the IUCN guidelines. The habitat of the species is severely affected by landslides. As a result, effective strategies should be developed to protect I. megamalayana from exinction.

<p>A new name in the genus <em>Ledebouria</em> Roth is validated for <em>Scilla viridis</em> Blatter &amp; Hallberg [non <em>Scilla viridis </em>(L.) Salisbury].  It is rediscovered after about 85 years of its first and only report.  It is also redescribed on the basis of morphology, anatomy, cytology and assigned the name <em>Ledebouria junnarensis </em>S.S. Rahangdale &amp; S.R. Rahangdale belonging to the family Asparagaceae, subfamily Hyacinthoideae.  As this is a species endemic to the Western Ghats, Maharashtra, India, it is studied for threat status as per IUCN criteria &amp; guidelines and assigned the status Critically Endangered B1ab(iii)+2ab(iii).  Identification keys for the genera and species of subfamily Hyacinthoideae reported from India are prepared on the basis of reported and observed characters.</p><div> </div>

The critically endangered Phyllanthus talbotii Sedgw. (Phyllanthaceae) is endemic to the northern part of the Western Ghats in Goa and Karnataka, India. The species was described in 1921 from collections made in 1883, 1918 and 1919, and then rediscovered in 1969. We report here a new locality, Netravali Wildlife Sanctuary, South Goa district, Goa. The species is lectotypified and a detailed description is provided, including distribution, IUCN threat status, conservation measures and nomenclatural notes.

Abstract The study aimed to develop an efficient, rapid, and large-scale in vitro regeneration system for propagation, conservation, and restoration of an endemic and critically endangered herb, Ceropegia mohanramii. The cultures were established using nodal explants on Murashige and Skoog’s (MS) medium supplemented with 6-benzylaminopurine (BAP: 1.0 mg/l). Nodal buds cultured on MS medium supplemented with BAP (2.0 mg/l) along with indole-3-butyric acid (IBA, 0.5 mg/l) resulted with production of maximum number of shoots (17.1 ± 1.2) in hundred percent of the cultures. MS medium supplemented with BAP (2.0 mg/l) along with diverse concentrations of indole-3acetic acid (IAA) promoted the in vitro flowering. In vitro regenerated shoots were transferred to one-half MS medium fortified with singular supplementation of auxins, where IBA (1.5 mg/l) served optimal for production of maximum number of roots (5.7 ± 0.6). In vitro derived plantlets were hardened under controlled conditions in a glasshouse and subsequently transferred to soil. Over 1200 saplings were transplanted to eight different localities of the Western Ghats where over 76% survival is recorded after 1 year of transplantation.
