but the other, the eastern A. brachypetala, is somewhat anomalous in the petals being 
almost reduced to the concave lower portion, thus bringing the plant technically near 
Jfelodorum or Fopowia. The habit, however, and other characters do not admit of 
its removal from Artabotrys, and the petals do occasionally appear to be produced 
into a short acumen at the top.

Doubtful Species. 
A. sp. ? A small tree, apparently without hooks. Inflorescence in other respects and 
shape of the flowers as in some species of Artabotrys ; but in our specimens they are all 
males.

This small genus has two African and one Madagascar species, the third African 
species mentioned in our < Genera' proving to be a variety only of S. senegalensis. The 
African ones are both remarkable for the transverse undulations and folds of the petals 
(or lobes of the coroUa), especially when the bud is near opening, which is not alluded 
to in the description of the Mascarene plant, and which was therefore omitted in 
the generic characters, drawn up before our H. gremdifiorus was received ; but as it 
occurs in both these species, it is probably characteristic of the genus. These petals
