 San Felipe, California ; Parry. Between San Diego and the Rio Colorado ; ScJiott. Monterey; 

 ili?\ Andreics. A tall branching plant, (3 — 4 feet high,) with showy golden yellow blossoms in 

 panicles. It differs from Dicentra in the filaments of the two phalanges being united nearly to 

 the summit, where alone they are distinct ; in the dull verrucose horse-shoe-form seeds, which 

 are thick on the margin^ and destitute of a strophiole or crest ; and^ lastly, in a peculiar habit. 

 The pollen is spherical, as in Dicentra. It may be considered as the type of a genus or sub- 

 genus, to which the name of Chrysocapnos would not be inappropriate.

 plant agrees exactly with ours, but it has only very young fruit. The ripe fruit and seeds have 

 probably not been seen before.
