BIXINE^E 



199 



Leaves simple, cauline, alternate, stipulate, petiolate, palmately- 

 nerved and lobed, thinly glandular- scurfy along the nerves on both 

 surfaces; petioles subterete, slightly channelled on the upper surface, 

 glan dular- scurfy ; stipules small, subulate, acute, soon becoming 

 brown. 



No. 1. Ovate or subelliptic, coarsely serrated above the middle 

 or subtrifid with alternate ascending nerves. 



Nos. 2-4. Palmately five-nerved and trilobed, or the 3rd and 4th 

 slightly five-lobed; lobes triangular, obtuse, and rounded or acuminate 

 and subacute, crenate-serrate, with the terminal lobe the largest. 



No. 5. With more elongated and more ovate leaves, otherwise 

 similar. 



NOTE. The seed of Cochlospermurn is cochleate-reniform or 

 spiral. The embryo is incurved and the cotyledons ovate while still 

 in the seed, which would account for their unusually elongated cha- 

 racter after germination. The cotyledons of other members of the 

 Order coming under my notice are short and very broad or rounded.
