Trips X.—LEPIDINE. 
Cotyledons flat, 7. e. bent over close to the base, with the radicle 
lying on the back of one of them (incumbent), or bent over in the 
middle, the lower portion being in the same line as the radicle, the 
upper portion lying against the radicle, which is on the back of one 
of them. Pod short and broad, compressed at right angles to the 
direction of the replum, generally opening by 2 convex valves, with 
frequently a wing down the central line of the back or part farthest 
from the replum. 
GENUS XXTIT—CAPSELLA. Monch, in D. C. 
Sepals nearly erect, equal at the base. Petals equal, entire, or 
none. Filaments without wings or appendages. Pods compressed 
at right angles to the replum, wedge-shaped, obovate, obcordate at 
the apex or elliptical-ovoid; valves keeled but not winged; style 
short. Seeds rather numerous, oblong-ovoid, not margined. A 
genus of which one of the species (C. Bursa-pastoris) has the habit 
of Thlaspi, the others that of Hutchinsia. 
The name of this genus is a diminutive of capsula, a capsule.
