Abstract

The anatomy of the leaf blade, petiole, stem and root of the genus Sarcocaulon (DC.) Sweet is discussed. On the basis of the leaf anatomy, the four sections recognized by Moffett (1979) can be identified: section Denticulati (dorsiventral leaves), section Multifidi (isobilateral leaves and adaxial and abaxial palisade continuous at midvein), section Crenati (isobilateral leaves, short curved trichomes and glandular hairs), section Sarcocaulon (isobilateral leaves and glandular hairs only). The anatomy of the stem is typically that of a herbaceous dicotyledon with a thick periderm. The root structure shows that the function of the root is not food storage.
