Diagnostics:

Manihot carthagenesis subspecies glaziovii is a common shrub that is usually found at forest edges under bright sun. The leaves are palmately lobed that are broader that the tip, and usually comes with red petioles. 

It closely resembles a relative, the Tapioca (Manihot esculenta) but the latter have smaller leaves as well as narrow and more linear leaf lobes. The colour of the petiole is usually green too.


Interesting Facts:

While currently classified as a subspecies under Manihot carthagenesis, da Silveira et al. (2019) suggested that based on morphological and ecological traits, phylogenetic evidence, and haplotype network analysis, this be placed as a unique separate species as Manihot glaziovii.
