My specimen of this interesting plaut is unfortunately unique, so that material for 
ascertaining facts of structure is not available. The most noteworthy point is doubtless 
the calyx of the female flower. The small section Decalobiwm of Croton contains two 
species, C. sincorensis, Muell. Arg., from Bahia, and C. decalobiwm, Muell. Arg., a 
Central American plant; these have an unequally 10-partite calyx with entire lacinie; 
the quinary symmetry is therefore not departed from. Julocroton has pectinate calyx- 
laciniz, like those of our plant, but the upper (posticous) lacini: are greatly reduced in 
size (rudimentary in fact), and the lower one is larger than its lateral fellows. Hetero- 
croton unites the actinomorphic calyx of Croton with the pectinate lacinie of Julocroton, 
and differs from both in the absence of quinary symmetry. 
The specimen has only one ovary, which, after being opened, has been carefully 
secured in a capsule, so as to be available for future examination. I feel very undecided 
about the placentation, as all I could with certainty make out was a couple of ovules 
lying immersed in a magma. Whether we have here something resembling the
