OF THE MATTO GROSSO EXPEDITION, 1891-92. 463 
placentation of Crotonopsis— and I should not be surprised if this were the case— 
can be determined only when more material comes to hand. 
Through water getting into the ‘Explorer’ I lost about ten per cent. of my 
Santa Cruz plants, and I suspect that specimens of Heterocroton must have been 
among them. 
I have omitted a diagram of the female flower, as the nature of the ovary is so 
uncertain. The specific name is an expression of the homoplasy between the plant and 
Croton antisyphiliticus, Mart., and, to judge from the figure, C. Tamberlikii, Muell. Arg.
