Materials for a Flora of North Bihar-I: Champaran District

Abstract

The present paper deals with the vascular plants collected from Champaran District, North Bihar, deposited in the Central National Herbarium (CAL). The work presented here does not purport to be a complete one. A Flora of North Bihar could be attempted on the basis of a lot of more field works in due course.

The enumeration includes 552 species, 16 varieties under 362 genera and 84 families. The leading families are Leguminosae with 61 species and 4 varieties, Gramineae with 55 species and 1 variety, followed by Cyperaceae with 30 species, Euphorbiaceae with 29 species and 1 variety and Compositae with 26 species respectively. The arrangement of families and genera is according to that of G. Bentham & J. D. Hooker in Genera Plantarum (1862-1883) and the sequence of specific and infraspecific taxa is according to the arrangement in J. D. Hooker's The Flora of British India (1872-1897). The nomenclature has been checked and revised wherever necessary.
