 base, glabrous, biconvex, spreading horizontally, 9-11 mm. long. 



Stem with its internodes undeveloped in the seedling stage. 



Leaves simple, radical and cauline, alternate, exstipulate, petio- 

 late, with scattered hairs at least in the young state, brittle, bright 

 green ; petiole channelled above, with a prominent ridge beneath, 

 sheathing at the base, narrowly winged as if the leaf were decurrent 

 upon it. 



Nos. 1-2. Narrowly spathulate, obtuse, slightly mucronate, 

 tapering gradually into the petiole, entire. 



No. 3. Bi- to tri-fid with alternate segments. 



Nos. 4-5. Trifid, or 4th to 6th irregularly pinnatifid.

Primary root long, tapering, with short lateral rootlets, yellowish, 

 annual. 



Hypocotyl short, tapering downwards, pale and stained with 

 red, glabrous, mostly subterranean, about 4 mm. long. 



Cotyledons linear, deeply bifid, segments acute, biconvex, gla- 

 brous, glaucous, dilated at the base and perfoliate, 2-8 to 3 cm. long 

 (segments about T8 cm. long), 1 mm. broad below the fissure.
