Abstract
The morpho-anatomical characters of 18 species belonging to six genera of sub-family Rosoideae were
investigated. The anatomical characters of both the pericarp and testa were found to be impracticable for species
delimitation since they are consistent at the generic level. The same reason rendered the character evaluation
invaluable within the species of the same genus. Of the morphological characters the mode of the achene
vasculature as well as its ramification varied in the different taxa. The basic number of the achene supply is one
median and two lateral strands. The behaviour of the latter, whether distinct or fused, as well as the ramification ,
or not, of a part or the whole of the vascular skeleton led to the suggestion of a key-like layout which shows the
pathway of these character states as being primitive vs advanced.
