Cayaponia kathematophora is remarkable in its very 
large fruit and seed. Indeed, it is cultivated for the large, 
shining, brownish seed which, hollowed out, is employed 
in the manufacture of anklets and necklaces. The specific 
epithet (meaning ‘“‘necklace bearing’’) refers to this use. 
This new species further differs from others known 
from the Amazon basin in its very densely and softly 
lanate-hispidulous leaves which are lobed, not trifoliolate. 
Even though the flowers in the type material are not well 
enough preserved for description, the vegetative and 
fruit characters alone are sufficiently distinct to allow 
the recognition of a new concept.
