This species is somewhat anomalous in the Annonaceae in its mono- 
carpellate flowers, although occasionally one finds species in various genera 
with single carpels, and is likewise anomalous within the genus Desmos : 
Lour. (Unona auctt. non Linn.) not only in this character but also in its 
sessile depressed-globose, somewhat hairy stigmas, and much thickened 
fruits which are only slightly constricted between the two seeds. While it 
seems probable that ultimately it may be desirable to establish a new genus 
for this rather striking form, in view of the slight amount of material avail- 
able (a single flower dissected) it seems best to place it in Desmos for the 
present. It is not closely allied to any previously described species in 
this group.

The leaves of the cited specimen are twice as large as Steward admits 
for Hooker’s species, yet I believe that the material is properly placed under
