Hemidactylus frenatus Duméril & Bibron, 1836 usually occur in pairs, is commonly found in human settlements and is thus known as a ‘house gecko’. It only rarely inhabits undisturbed forests in the wet zone though it is comparatively common in dry, intermediate and semi-arid forests in Sri Lanka. This nocturnal species spends daytime in crevices but feeding during daytime has been observed. Although it is not highly territorial, most individuals seem to occupy the same place for an extended period. Group behavior can also be observed, especially within human habitations in the dry zone. This species can commonly be seen on lampposts where it waits for insect prey to be attracted to the light. In addition to the expected assortment of insect prey it also commonly feeds on rice, bread and other household food and hence has become a ‘pest’ in most houses. Habitual cannibalism is shown by some adults as they feed on juveniles. Eggs as a part of a gecko’s diet, whether of their own species or those of another species, are recorded in captivity. In this paper we describe the egg-feeding behavior of H. frenatus in the wild.
Wolf spiders (Arachneae: Lycosidae) are one of the successful hunters which extend their range through various habitats such as wetlands, springs, and sandy coasts, though less information is available on their feeding and predatory behaviour. During the course of regular field visits for an ecological study of benthic fauna on the Mahi estuarine mouth at Gulf of Khambhat, on the western coast of India (22°12’59.13”N, 72°36’55.47”E), interesting observations about the prey-predation relationship between the wolf spider (Lycos sp.) and two crab species Uca lactea annulipes and Cardisoma carnifex were recorded.
Based on the collections from Travancore, India (Chemunji hills, Muthukuzhivayal Bourdillon s.n.), Bourdillon (1904) described and illustrated Eugenia rama-varma Bourd. (Myrtaceae, as “Rama Varma”, “named after H.H. [Mulam Thirunal Rama Varma] the Maharaja of Travancore”, with a comment: “a very handsome evergreen tree found at high elevation above 4000 ft”. Gamble (1919) transferred it to Jambosa, as J. rama-varma (Bourd.) Gamble. Later Chithra in Nair & Henry (1983) transferred it to Syzygium and made the combination S. rama-varma (Bourd.) Chithra (as “rama-varmae”).

Taxonomic notes on two Jasminum species (Oleaceae) from India
E.S.S. Kumar & A. Sabeena *Corresponding author. E-mail: santhoshkumares@gmail.com
During systematic studies of Jasminum L. in Kerala, the authors collected a curious species from the wild as well as from cultivation. Critical study based on relevant literature and type material allowed us to identify the plant as J. azoricum L. Consultation of other regional herbaria in India revealed that several similar specimens were erroneously determined as J. flexile and many sheets of J. flexile were identified as J. azoricum. Searching the literature and other regional floras showed considerable confusion about the identity of these two species in India.
While surveying floral diversity of Bundi district in southeastern Rajasthan, we noticed, on 6 March 2008, a parasite on the roots of Vitex negundo L.. The parasitic plant was seen at Rain village (25º3823.10N, 75º4034.09E; 286 m a.s.l.) in Hindoli tehsil of Bundi District, 22 km north from Bundi, on a field bund. Terrain of the field was quite flattish having a small rainy seasonal nallah on its eastern edge that is close to a government primary school building. Vitex negundo L., Woodfordia fruticosa (L.) Kurz and Mimosa himalayana Gamble were commonly growing along the banks of the nallah and on bunds of the field. The site was continuously checked during winter, summer and rainy seasons to observe the species’s growth pattern until 2011. The parasitic plant starts appearing in the root zone of V. negundo at the end of the rainy season, and fruits at the beginning of the summer season. Winter is the best time to see this plant when it flowers massively. This plant is an erect herb, with purple scale-like leaves and yellow, sessile flowers in a terminal raceme. The three purple streaks on each petal are diagnostic. Aerial parts of young plants initially appear greenish-white, but soon turn purple. The stems are rhizomatous with numerous axillary buds. On digging, fresh rhizomes are orange-yellow in colour. After drying, they become black. The species was identified as Alectra chitrakutensis (Rau) R. Prasad & R.D. Dixit, 1993. Locally it is known as negad ki bunti.
