Abstract The Indian peafowl (Pavo cristatus), the largest of the pheasants in India, inhabits mostly semi-arid conditions. We examined the courtship displays of free-ranging peacocks in relation to the orientation and the relative positions of females being courted from August 2012 to January 2013 in Viralimalai, Tamil Nadu, India, to address these questions: (1) Do the peacocks orient their courtship display towards the sun? (2) Is there any relationship between the presence of peahen and the duration of display of peacock? (3) Is there any site-preference to display? We found that the majority of the displays were oriented towards the sun initially, but then oriented towards peahen (regardless of direction) soon after their arrival. Although peacock displayed even in the absence of peahen, presence of peahen influenced the display duration of peacock. Displays were performed largely in open areas.

Solanum diphyllum L., commonly known as two-leaf nightshade, is native to Mexico south to Costa Rica in Central America but widely naturalized in many tropical and subtropical regions of the world having escaped from cultivation. The first occurrence of S. diphyllum in India was reported in 1995 from two locations in the Howrah District of West Bengal where it was known from only a few individuals. The species went unnoticed for several years until a large population near Bhushi dam and the Ambavane area of Lonavala town, Pune District, was found by the senior author in 2006. According to local sources the species had been present for seven or eight year and, in 2006, it was found to have occupied grasslands and forests edges in the towns of Lonavala and Khandala as well as most of the wastelands of Pune, Pimpri-Chinchwad, and other nearby towns. It was also found in various botanical gardens in the city of Pune including the Empress Garden, Mudwa Experimental Garden of Botanical Survey of India (BSI), the associated garden of BSI office campus, and other public gardens.
Cyperus L. (Cyperaceae) contains about 600 species and distributed mainly in the tropics. In India, it is represented by 70 species, of which 48 are found in Kerala State. It is a taxonomically complex genus and the treatment of Cyperus by Kuekenthal in 1935–1936 is considered to be an useful treatment even now. They usually grow in wetland vegetation, mud banks, open areas, etc. While studying the sedge flora of Nilgiri Biosphere Reserve, the authors collected an interesting species of Cyperus, from the Western Ghats in the Wayanad District, Kerala State. On examination, the species was identified as Cyperus papyrus L., a naturalised ornamental in Africa and North America. Scrutiny of the literature revealed that it was not reported from Western Ghats earlier but known from Gujarat and Rajasthan, India.
The genus Canscora Lam, known presently from Africa, Australia and tropical Asia, is represented in India by 13 species of which ten are found in Kerala. During our taxonomic studies of Gentianaceae in Kerala, India, the authors collected a species of Canscora from the lateritic region of northern Kerala which, on critical examination and perusal of relevant literature, proved to be Canscora stricta Sedgw., a species hitherto known only from Karnataka State of central Western Ghats.
