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 

 Ifelodorum or Fopowia. The habit, however, and other characters do not admit of 

 its removal from Artahotvys, 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. 

 From the Gaboon River (G. Mann).

 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 corolla), 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. graiidiflorus was received ; but as it 

 occurs in both these species, it is probably characteristic of the genus. These petals
