Mr. Hooxer’s Observations on Andrea. 303 
capsule contains its portion of the seeds, besides the columella, 
which passes through its centre and is inserted into the apo- 
physis. | 
Andrea rupestris is found in less alpine situations than the last- 
mentioned species. On dry rocks, which afford nourishment to 
the various species of Gyrophore, and where there seems to be 
scarcely a particle of vegetable mould, this little plant may not 
unfrequently be met with.
