Elaeocarpus aristatus (Elaeocarpaceae): New for southern India
D.F. Irudhyaraj & R. Raju* *Corresponding author. E-mail: racprabha@yahoo.com
Species of Elaeocarpus L. (Elaeocarpaceae Juss.) are characteristically trees or shrubs distributed from Madagascar in the west to Fiji and Hawaii in the east; of the some 350 recognized species, the greatest concentration of species is found in Borneo and New Guinea. Most species of Elaeocarpus are large to medium-sized trees with buttressed root (in mature individuals) bearing raceme inflorescences with beautiful, fragrant flowers. Many species of Elaeocarpus are economically important as a source of timber, edible fruits, decorative seeds, and even as medicinals. Out of the some 120 species reported from Asia, 25 occur in India. In India, the species of Elaeocarpus are confined mostly to northeastern and southern India with a few species restricted to the Andaman and Nicobar islands. Six species, viz. E. blascoi Weibel, E. gaussenii Weibel, E. glandulosus Wall. ex Merr., E. munroii Mast., E. recurvatus Corner, and E. venustus Bedd. are endemic to southern peninsular India.

Rediscovery of Aeginetia indica L. (Orobanchaceae) from Meegahakiula, Sri Lanka after 125 years

Aeginetia indica L. (Orobanchaceae) is an herbaceous annual plant that lacks leaves and is parasitic on roots of monocots, especially grasses. The species is rare and declining throughout its range. In Sri Lanka it has a Redlist status of CR status. A small population of Aeginetia indica was discovered during botanical explorations while collecting and cataloguing plants in the village of Kalugahakandura, Meegahakivula District Secretariat Division of Badulla District, in December 2013. At that time, six mature individuals of Aeginetia indica were recorded in a small area approximately one square meter on a steep road-side forest floor (07°0606.19N, 81°0458.63E). Taxonomic identity was determined by comparison with specimens at the National Herbarium, Peradeniya, Sri Lanka, by submitting a voucher specimen (Reference No. 6/01/H/03) to the National Herbarium.
Based on two collections from the banks of the Periyaur (=Periyar) River in North Travancore, Bourdillon (1904) described and illustrated Eugenia occidentalis Bourd (Myrtaceae). Gamble (1919) transferred it to Jambosa, as J. occidentale (Bourd.) Gamble. Gandhi (1976) later proposed Syzygium occidentale (Bourd.) Gandhi. Neither Bourdillon nor subsequent authors designate a lectotype from among the two syntypes preserved at K nor did any author declare the published figure as the lectotype. Among the syntypes, K!, barcode no. 000793886, was used by Bourdillon for the diagnosis and illustration of E. occidentalis and hence this specimen is here designated as the lectotype.
During a bryophyte survey, Leptolejeunea epiphylla was collected at Mundanthurai and Palode in the Western Ghats, India. In both localities it was found to inhabit the leaves of Arenga wightii Griff., an endemic, understorey palm, commonly seen in evergreen and riparian forests of the southern Western Ghats. This record is an addition to the liverwort flora (especially to the epiphyllous flora) of the Indian mainland because in India, this species was so far known only from the Andaman and Nicobar Islands. It is one among the 11 species of Leptolejeunea (Spruce) Schiffn so far known to occur in India . The species is briefly described and illustrated, and its distribution is mapped.

Taxonomic status of Pavetta bourdillonii (Rubiaceae)
E.S.S. Kumar* & N. Mohanan *Corresponding author. E-mail: santhoshkumares@gmail.com
The genus Pavetta L. has about 300 species distributed in the paleotropical regions of the world. Bremekamp (1934) laboriously studied this genus in details but his narrow species concept resulted in the recognition of many more species than can be justified taxonomically. He recognized 42 species for the Indian subcontinent, while Rout and Deb (1999) accepted only 25 species. Most of the characters used by Bremekamp to delimiting species, such as stem characters (green vs corky), shape and size of leaves, and arrangements of bacterial nodules in the leaves, were rejected by Rout and Deb. However, the position of the inflorescence (axillary vs. terminal) was found to be useful taxonomically by both parties.
