250. Capsella den tata Raf. dwarfish stem 
simple nearly naked radical leaves petiolate 
cuneate or obovate toothed, stem leaves 1 or 2 
sagittate linear, raceme lax elongate, silicules 
deltoid truncate shorter than pedicels. — In mts. 
Alleghanies, 3 or 4 inches high only, akin to 
last, but leaves toothed and upper sagittate. 
Is it the V ar. minor of some botanists ? 
251. Capsella bifida Raf. several stems, 
radical leaves oblong toothed, stem leaves sa- 
gittate entire glaucous roughish, racemes elon- 
gate, silicules oblong base acute end bifid, pe- 
dicels subequal. — In Pennsylvania glades, pe- 
dal, annual, very distinct by silicules longer 
than broad and almost bifid, no runcinate 
leaves &,c. 
252. Capsella furcata Raf. all leaves spa- 
tulate oblong obtuse entire or hardly toothed, 
silicules broad furcate, pedicels equal — In Can- 
ada and Europe, semipedal, distinct by the pe- 
culiar silicules broadly obdeltoid, wider than 
long, and uniform leaves, quite obtuse. 
253. Capsella amblodes Raf. all leaves pin- 
natifid, acute, pinnules often angular, silicules, 
shorter than pedicels, oblong cuneate obtuse, 
emarginate — sent me from Europe as a varie- 
ty of C. bursa , probably also in N. America, 
annual dwarfish 3 to 4 inches high only, qnite 
peculiar silicules, and uniform leaves. 
254. Capsella bursa Raf. non Auct. 
Thlaspi bursa pastor is L. and most of our 
botanists. Radical leaves pinnatifid runcinate, 
pinnules entire, stem leaves oblong sagittate den- 
tate, silicules shorter than pedicels deltoid tri- 
angular base and corners acute, hardly emar- 
ginate — In Europe, introduced in fields and 
the roads in N, America, pedal and sesquipe-
