Cyperus papyrus L. (Cyperaceae): a new record for Western Ghats, India
A.R. Viji, S. Deepu & A.G. Pandurangan*
*Corresponding author. E-mail: agpandurangan@gmail.com
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.

Canscora stricta Sedgw. (Gentianaceae): an endemic species of Western Ghats
M.P. Geethakumary, A.G. Panduranga*, & P. Ravichandran
*Corresponding author. E-mail: agpandurangan@gmail.com
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.

A COMPILATION AND ANALYSIS OF FOOD PLANTS UTILIZATION OF SRI LANKAN BUTTERFLY LARVAE (PAPILIONOIDEA)
H.D. Jayasinghe*, S.S. Rajapaksha & C. de Alwis
*Corresponding author. E-mail: himesh.jayasinghe1@gmail.com
Abstract
Larval food plants (LFPs) of Sri Lankan butterflies are poorly documented in the historical literature and there is a great need to identify LFPs in conservation perspectives. Therefore, the current study was designed and carried out during the past decade. A list of LFPs for 207 butterfly species (Super family Papilionoidea) of Sri Lanka is presented based on local studies and includes 785 plant-butterfly combinations and 480 plant species. Many of these combinations are reported for the first time in Sri Lanka. The impact of introducing new plants on the dynamics of abundance and distribution of butterflies, the possibility of butterflies being pests on crops, and observations of LFPs of rare butterfly species, are discussed. This information is crucial for the conservation management of the butterfly fauna in Sri Lanka.

POLLINATION ECOLOGY OF Lumnitzera racemosa WILLD. (COMBRETACEAE), A NON-VIVIPAROUS MANGROVE TREE
A.J. Solomon Raju*, Rajendra Kumar & B. Rajesh
*Corresponding author. E-mail: ajsraju@yahoo.com
Abstract
Lumnitzera racemosa is a non-viviparous evergreen mangrove tree species. It is a massive bloomer from mid-July to mid-August. The flowers are bisexual, self-compatible, self-pollinating and exhibit a mixed breeding system. The plant is temporally dioecious with marked protandry and a non-receptive stigma on day one of anthesis with a receptive stigma on days two and three. Fruit set is approximately 90% due to self and cross-pollination. The floral characters are related to pollination by generalized flower-visiting insects, notably actinomorphy, white spreading petals, limited but easily accessible nectar, and position of stamens. Pollinators include bees, wasps and butterflies. Fruits are invariably 1-seeded despite the presence of 3–5 ovules. Natural regeneration is low perhaps due to abortion of embryos or the feeding of embryos by small grubs. Fallen mature fruits become fibrous in water and this may aid dispersal in the sea. However, fruit germination and seedling establishment is curtailed due to their salinity-sensitivity.
