FIG 28-A. Dendrogram of relationships of the South American sections of Manibot. The simi-<br />

larity values are shown decreasing from left to right across the top of the Figure. Sectional numbers<br />

are given on the vertical axis.<br />

<strong>Manihot</strong> crassisepala is very similar to M. foetida. The insufficient representation of<br />

M. crassisepala and M. foetida in this study precludes confident delimitation of these two.<br />

It may be necessary to re-examine the taxonomic status of M. crassisepala, especially its<br />

relationship with M. foetida, when sufficient material and field data become available.<br />

In the original description of this species, the type local is reported as Colima.<br />

Photographs of the type are available, but it has not been possible to verify the label data<br />

with respect to the locality of collection. It seems highly unlikely that the range of this<br />

species extends to Colima, however further field studies would be necessary to delineate<br />

its complete range.<br />

The note in the original description of this species indicates that the mature seeds are<br />

edible.<br />
