_ I have referred this plant to Hutchinsia, wears the cotyle- 
ons are incumbent, in preference to puttin in Capsella, a 
truly natural genus, with which this does not Seca well in habit 
or form of pod. Dr. Arnott pointed out to me its affinity with 
Capsella obovata of Siberia, which is the Hutchinsia prostrata 
of some authors; a plant closely allied to the H. petraa of 
Europe, but agreeing with H. Tisetica in having incumbent co- 
tyledons. 7. 7.
