XXV.—SAPIUM CLADOGYNE, A NEW SPECIES FROM 
BRITISH GUIANA. 
J. HutcHinson. 
In December, 1910, a series of specimens of Sapium collected by 
Mr. F. A. Stockdale, Assistant Director of Agriculture, and others 
in British Guiana were communicated to Kew by Prof. J. B. 
Harrison, Director of Agriculture, for comparison with the type of 
S. Jenmani, Hemsl. 
female branches are detected only by close examination. The 
female flowers evidently attain maturity a considerable time after 
the fall of the male, the axis bearing the latter soon articulating at 
the base and leaving a large scar which can be plainly seen in the 
young and also in the mature fruiting stages. : : 
It appears to the writer that this difference in the time of 
flowering of the two sexes constitutes another important character 
erving to separate the species, for in S. Jenmani it is highly 
probable that pollination is affected by male flowers from the same 
individual, whereas in S. eladogyne this is obviously not possible, 
Field notes on this point would be of interest,
