. cotyledonis replicata. 
Oss. A plant very like this is figured in Royles illust. under 
name of Tauscheria desertorum. : 
The nature of the simple quasi perfoliate leaves is obvious 
and is analogous to what takes place in some Umbelliferz; 
and in a less degree to certain cases among Mimosez. 
The alternation of the parts is obscure, and the presence 
of the gland attached to the base of the petals, does not , al- 
low us to consider the longer stamina as belonging to the 
petals but that itis displaced. There is no proof of com. 
Position of the outer and larger sepals, or it would be of easy 
explanation. 
There is little doubt, but that several types of structure 
. prevail in the order independent of that of the seed; the 
Value of which has not been yet tested. It iscurious, that 
_ When three petals alone are formed no extra stamen is deve- 
loped.
