ABSTRACT
The anatomy f leaf and stem of eleven land races
of Discorea rotiundata was studied with the major aim of providing information
that could be necessary in the intraspecific taxonomy of Dis.crea rotiundata.
Results from the investigation have proved that the leaf and stem anatomy
exhibits such characters that could be included with other reliable attributes
of this species in an attempt to fashion out an authentic classification scheme
among the varieties of Discorea rotiundata. The presence of trichomes in the LE
(Lower epidermis) of Aloshi and Makakwusa, the significant difference in
stomata! frequencies and the straight anticlinal cells walls of Agbocha,
Nwayieri and Dorban were majcr significant characters of the leaf epidermis
seen. The nature of the stem; thickness of the stem cortex and number of
vascular bundles and hairness of the stem are the features of the stem
exploited in the systematic consideration of these Discoreg species varieties.
The 10-12 layered cells of the cortex in Makakwusa, He-abalo separates them
from other varieties studied. The vascular systems are arranged in a circular
outline in all the land races investigated except in Dente which is at @
triangular in shape which distinguishes it from other varieties . . The
relevance of all these observations on leaf and stem anatomy of 11 land races
of Discorea rotiundata studied were discussed in details.
