dots, obscurely alternately penninerved, pinnatisect with linear, 

 obtuse, entire segments, revolute at the margins so as to make them 

 convex above, and concave or furrowed beneath ; petioles semi- 

 terete, glabrous, channelled above with rather acute edges, reddish, 

 dilated and clasping at the base. 



No. 1. Linear, pinnati-fid or -sect, with a few subulate, obtuse, 

 alternate segments ; middle ones longest ; terminal one triangular- 

 hastate. 



Nos. 2-6. Gradually longer and larger, pinnatisect with alter- 

 nate, obtuse, subulate and linear segments ; terminal lobe becoming 

 less and less conspicuous until it is almost absent, the leaf ending 

 in two lateral segments.

Seed narrow, oblong 1-1-25 mm. long, testa thin, membranous, 

 smooth ; hilum inconspicuous.

 tuse, entire, plano-convex, lying face to face ; radicle short, subacute,

 pubescent in the young state or almost glabrous, sessile or at least
