seems to me that the reason may be that this specimen 
was collected from a young plant; the texture of the 
leaves also indicates this. On all young plants one finds 
near Hevea guyanensis, the typical characters do not 
appear; they also have leaves characteristic of Hevea 
brasiliensis.” 
Credit must go to Cramer for his perspicacity, but the 
suggestion that the specimen is referable to Hevea bra- 
silensis cannot be accepted in view of the characters ex- 
hibited in the tip and scales. 
This is apparently the first time Hevea pauciflora has 
been recorded for the flora of French Guiana. Hitherto, 
the only species known from that colony was Hevea 
guianensis. 
Similarly, till now Hevea pauciflora has never been re- 
ported from Dutch Guiana, although it is not uncom- 
mon in adjacent British Guiana. I have found a Surinam 
specimen in the herbarium at Utrecht which seems to 
represent this species. It is sterile, but the tip of the leaf- 
let shows it to belong to Hevea pauciflora, not to H. 
LUIANENSIS.

The specimen of this collection which is preserved in 
the Humboldt Herbarium in Paris was annotated with 
an unpublished name in Siphonia honoring Schomburgk. 
The annotation seems to have been made prior to 1865, 
for since that year the generic name Hevea has been uni- 
versally accepted by all who have worked seriously with 
the group. I was unable to ascertain in whose handwrit- 
ing the annotation was written. It is significant in being
