This very natural genus includes two species common about 
the Cape, and known to Linnzus and other older authors, who 
associated them either with Indigofera or Borbonia. De 
Candolle, who mistook one of them for the Liparia sericea of 
Linnwus joined them with Priestleya, from which Ecklon 
and Zeyher and E. Meyer again separated them, the former 
under the name of Amphithalea and the latter under that of 
Ingenhoussia. In both of these works, however, the genus 
includes several monadelphous and diadelphous species, the 
one giving as the generic character “ Stamina diadelpha (9 et 
1);" the other, * Stamina submonadelpha, decimum uno 
latere reliquis ima basi junctum." It will be found, however, 
on examination, that some species are entirely diadelphous, 
as in Priestleya, and others have all the stamens nearly equally 
connected, though often very shortly so. As the latter have 
also some constant differences in habit, and especially in the 
leaves, which are always more or less involute, not revolute, 
I have adopted for them the genus Coelidium, well indicated 
by Vogel, and published by Walpers. 
Ecklon and Zeyher had separated from Amphithalea, under 
the name of Cryphiantha, a species to which rather broader 
leaves and small flowers give a little difference in habit, but 
none, that I can perceive, in character, and I have therefore - 
followed Meyer and Walpers in retaining it as a species of — 
Amphithalea. The A. cuneifolia Eckl. et Zeyh. has also been © 
established as a genus by Walpers, and has, it is sue; A 
longer pod, and usually four ovules, but (if, as I bave little 
doubt, I am not mistaken in the identity of the plant) it has 
precisely the habit of Amphithalea, and although the ovules 
in the genus are usually solitary, yet there are two in A. 
densa, and as to the character from which the name is de- 
rived, the tenth stamen being inserted on the claw of the 
vexillum, it must have originated in a mistake ; probably in 
pulling off the vexillum, as frequently may happen in dis-
