Abstract
Achenes morphology in Potentilla L., i.e. P. subarenaria Borbás ex Zimmeter and P. intermedia L. nonWahlenb. was examined with stereoscope and scanning electron microscope (SEM). Achenes of these taxa varied in shape, size, colour, the surface sculpture and in the dimensions of dorsal ridge and ribs. SEM analyses allowed distinguishing two morphological types of seed coats pattern: ruminate-reticulate sculpture due to well preserved epidermal cells in P. subarenaria and tuberculate sculpture in P. intermedia. The main taxonomic features of these two taxa are: the microstructure, size, shape and colour of achenes.
