摘要

Achene of Sibbaldia species, exhibits a significant micro-morphological diversity, which can be used as an important taxonomic tool for their identification. The shape, size and ornamentation on the surface of Achene of 9 species of Sibbaldia were examined by using the SEM. Achene’s are mostly obovoid, narrow obovoid, globular obovoid, with the range of variation reniform to orbicular. Mostly brown in colour, size ranges from 05 mm to 02.00 mm long, 04mm to 1.20 mm broad. Mircostructural features of achences of S. micropetala are different from all other species of Sibbaldia and thus its placement is questioned in genus Sibbaldia of family Rosaceae.
