R. Kottaimuthu*, N. Vasudevan & A. Saravanan
*Corresponding author. E-mail: kottaimuthu@yahoo.co.in
The paleotropical genus Memecylon L. (Memecylaceae DC. or Melastomataceae Juss. subfam. Olisbeoideae Burnett) has about 150–300 species. It is mainly distributed from tropical Africa, Madagascar, southeastern Asia and northern Australia to the Fiji Islands. In India, it is represented by about 32 species, of which 13 are endemic to Western and Eastern Ghats of southern India. Various workers have added 23 additional species for India either as new species or as new records.

A new location for Hubbardia heptaneuron (Poaceae)
R. Kr. Singh* & A. Garg
*Corresponding author. E-mail: rksbsiadsingh@yahoo.co.in
Presumed to have become extinct, the pendulous annual grass, Hubbardia heptaneuron Bor, became the subject of immense botanical interest due to its unusual habitat preference. Hubbardia Bor with a single species, H. heptaneuron, was described by N.L. Bor (1951) on the basis of two specimens sent to him through Rev. H. Santapau (1903–1970). These specimens were actually collected in 1919 by L.J. Sedgwick (1883–1925) from Jog Falls, then known as Gersoppa Falls. Initially placed under tribe Isachneae Benth. by Bor, the extremely habitat and morphological characters of the new genus entirely differentiated this remarkable species from all other grasses of the world. This led to the establishment of a monogeneric tribe, Hubbardieae C.E. Hubb. Hubbardia heptaneuron was thought to have been rediscovered in 2002 on the basis of a 2000 S.R. Yadav collections from Tillari Ghat, Kolhapur District in Maharashtra.

Crotalaria globosa (Fabaceae): An overlooked endemic legume of India
R. Kottaimuthu* & N. Vasudevan
*Corresponding author. E-mail: kottaimuthu@yahoo.co.in
The genus Crotalaria, commonly known as ‘rattle pods’, is one of the more prolific genera in Fabaceae Lindl., with about 690 species distributed throughout the tropics. In India, the genus is represented by 93 species and in Tamil Nadu 53 species, of which five entities are endemic to Tamil Nadu: C. digitata Hook., C. fysonii var. glabra Gamble, C. globosa Wight, C. kodaiensis Debb. & Biswas. and C. ramosissima Roxb. var. ramnadensis A.A. Ansari. In connection with the documentation of legumes of Dindigul District for a doctoral dissertation by the first author, a few interesting specimens of Crotalaria were collected from Batlakundu and Ottanchathram hill ranges of Dindigul District. Critical study with relevant literature has confirmed it as Crotalaria globosa Wight. The type specimens, housed in the online herbaria of Kew and Edinburg, were also studied to ascertain identity of species.

On abnormal leaves in Chlorophytum borivilianum (Asparagaceae)
S.K. Sharma*
*Corresponding author. E-mail: sksharma56@gmail.com
Chlorophytnum borivilianum Santapau ex R.R. Fern. is a perennial geophyte that perennates with the help of tubers. The digitate sessile tubers are born on the undersurface of a discoid stem. A cluster of 10–17 leaves is produced by the perennating stem with the onset of the monsoon or just few days before onset of the monsoon. Generally one flowering scape is produced by the each plant. However, on occasions more than one scape may also be produced by an individual plant. This is an important medicinal species which is confined mainly to the southern part of the state of Rajasthan.

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.
