We cannot reconcile this with any of the described 
species of Triumfetta; but it must be confessed that their 
characters are in most cases so imperfect that it is no easy 
task to come to a decision in the genus. Next to the 
absence of petals, the number of cells in the ovarıum forms 
one of their most important points of difference, and yet in 
books there is scarcely a species in which that character 1s 
introduced. Some are 4-celled, some 3-celled, others 
6-celled; and from this circumstance we know that much 
aid is to be derived. If we had sufficiently attended to 
this, we should have avoided confounding, in another L5 
with Jacquin's Triumfetta rhomboidea, which has uniformly 
a 6-celled ovarium, a Peruvian species with 3 cells only,
