REMARKABLE TIBETAN PLANTS. 
racter agrees pretty well with Sisymbrium, unless the pods should prove 
to be permanently indehiscent. Those which I possess show no ten- 
 deney to dehiscence, but though sufficiently advanced to exhibit the. 
structure of the embryo, they are certainly immature. Notwithstand- . 
ing the remarkable habit, I am unwilling to propose a new genus on. 
imperfect materials, and therefore for = present leave it doubtfully in 
Sisymbrium.

The specimen figured exhibits the usual state of the plant. Th 
plate in Jaequemont's Voyage represents a large specimen in a very ad- 
vanced state. "The leaves, which vary much in shape, are often quite 
as much divided as in C. elegans, Camb., which seems to be nothing but 
a form of the present species, no character, except a slight 
the degree of emargination of the petals, being pointed out. =
