The leaf anatomy of nine species of Manihot Mill. were studied with the
objective of finding anatomical features that contribute to understanding
the taxonomy of the genus. Leaf samples were collected in the field and
from herbarium specimens, and standardized methods were used for both
light and scanning electron microscopy. The following species were
studied: M. bellidifolia P. Carvalho & M. Martins, M. brachyandra
Pax & K. Hoffm., M. caerulescens Pohl, M. diamantinensis Allem, M.
elongata sp. nov. ined., M. jacobinensis Müll. Arg. (I), M. jacobinensis
Müll. Arg. (II), M. longiracemosa P. Carvalho & M. Martins, M.
maracasensis Ule, M. reniformis Pohl, M. tripartita (Spreng) Müll. Arg.
and Manihot sp. Anatomically, the analysis revealed differences that
indicate the importance of leaf anatomy in the taxonomy of the species.
Presence of fibers in the bundle sheath, presence or absence of papillae
and fibers in the midrib are diagnostic characters. Although these
characteristics were not enough to separate all of the species, or to
group them into a section, they did show some taxonomic importance at the
species level. In addition, morphoanatomical differences and geographical
distribution support Manihot sp. as a distinct species.
