A chromosomal count of Hypochoeris plants collected at Ootacamund indicated the identity of those plants as H. radicata L., thus pointing to its presence in the Nilgiris, in addition to H. glabra L. reported in earlier works. This is confirmed by a detailed morphological study of living plants and herbarium specimens. A gradation in morphological characters between the two species leading to a possibility of interspecific hybridization is suggested. This may also account for the earlier misidentification of H. radicata with H. glabra. A table showing distinctive characters of the two species is provided.- Notes on Indian Commelinaceae-II: Cytological Observation

Chromosome numbers of 12 Species of Commelina have been worked out of which the chromosome numbers of 6 species and one variety are reported for the first time. In view of the misidentification of many species by earlier workers, reinvestigation of the chromosome numbers of some of the species has been suggested to confirm their earlier reports. A few new combinations are also added.- Notes on Indian Commelinaceae-III: Cytological Observations

Chromosome numbers of 18 species under 4 genera are studied of which the chromosome numbers of 6 species are recarded for the first time. Four species show variation from earlier reports. Aneuploidy and polyploidy are noted in Cyanotis and Murdannia. Reinvestigation of chromosome numbers of some of the species by earlier workers has been suggested to confirm their earlier reports. Possibility of a separate generic status has been suggested for the Ochreaeflora section of Cyanotis. A few new combinations are also added.- Notes on Indian Commelinaceae-IV: Cyto-Taxonomic Observations

Chromosome numbers of 29 species and one variety under six genera have been studied of which the chromosome numbers of 9 species and one variety are recorded for the first time. Five species show different chromosome number from previous reports. Further cyto-taxonomic evidence confirm that Aneilema (sensu stricto) is distinct from Murdannia. Majority of the Indian species of Commelina and Cyanotis (sensu stricto) show x=15 and 12 respectively. A new genus name Amis-chophacelus Rolla et Kammathy has been proposed for the ochraeflora section of Cyanotis (sensu lato) on the basis of clear cyto-taxonomic evidence. Aneuploidy, euploidy and intra-specific polyploidy have been observed in different species of Murdamia. Both morphological as well as cytological evidence do not suggest the separation of Aclisia from Pollia. Consideration of the hairy form of Streptolirion as S. volubile var. khasiana seems to be approprate. A new combination is proposed.- A Contribution towards a Flora of Biligirirangan Hills, Mysore State

Biligirirangan hills in Mysore State are somewhat isolated from the other hill ranges in the Western ghats, and the Nilgiris. This sketch of the vegetation is based on detailed collections made by the authors as well as the collections made some 28 years ago by Barnes. The enumeration includes 825 species of vascular plants under 484 genera and 133 families.- Anatomy of Vetiveria zizanioides (L.) Nash

Vegetative anatomy of the ischolar_main, stem and leaf of Vetiveria zizanioides (L.) Nash has been studied. Air cavities in the leaf-sheath and blade show stellate cells representing diaphragm interspersed by sclerotic strands which earlier have not been reported. The origin and structure of the diaphragm and the sclerotic strand have also been worked out.- Pharmacognostic Studies on the Genus Solanum Linn. Part I
