Abstract

Epidermal chargcters and venation pattern of leaves of ten Indian species of Polygonum Linn. belonging to five sections viz., P. recumbens Royle ex Bab. (Sect. Avicularia Meissn.) ; P. affine D. Don, P. amplexicaule Don, P. vacciniifolium Wall. ex Meissn. (Sect. Bistorta Tourn.) ; P. glabrum Willd., P. lupathifolium Linn., P. serrulatum Lagasc. (Sect. Persicaria Meissn.) ; P. chinense Linn., P. nepalense Meissn. (Sect. Cephalophilon) and P. rumicifolium Royle ex Bab. (Sect. Aconogon Meissn.) have been investigated for an appraisal of the extent of utility of these characters with regard to the taxonomy of this interesting group. The variability pattern in these features has been found to be independent of the established pattern at sectional level as set by criteria of external morphology. However, these do serve as helpful data of diagnostic value.
