80 Flora Neotropica
Inflorescence a monoecious panicle, ca 9.0 cm long, sparsely branched. Bracteoles
setaceous. Pistillate flowers restricted to the base of the upper half of the panicle.
Staminate buds ovoid ellipsoid. Fruits non vidi. Seeds non vidi.
DISTRIBUTION. (Fig 30A). Growing wild near Riacho de Santa Anna, Bahia, Brasil.
LOCAL NAMES. Manicoba (Zehntner 598).
The only representation of this taxon in this study is a photo of the type and the
inadequate representation precluded an accurate evaluation of this Ule species. The leaf
and inflorescence structure closely resemble Manihot esculenta, however, the use of this
species as a source of inferior rubber, as reported by Ule (1914) indicates that species
may be affiliated to members of the sect Glaziovianae.

This species is most closely related to M. surinamensis. The 'skyline' (Fig 28)8
indicates that the 2 species have a high similarity.
