approach each other in aspect, in niany forms ; but it is 

 impossible for a Californian botanist to regard the extremes 

 as mere variations of one species. 



25. L. MACEANTHUS. HosacMa macrantlia, Greene, Bull, 

 Calif. Acad. i. 81 (1885). AVhile this may be an extreme 

 form of L. grandiforns, no writer has credited that species 

 with foliaceous stipules which are caducous, leaving a perma- 

 nent gland-like scar. It was ou this character chiefly that I 

 relied when prox^osing the species as new; nor have I yet 

 found such stipules in any form of undoubted L. grandljlorus. 

 The present plant, then, joins this group to the next witli 

 scarcely a break.

 Proc. Am. Acad, xxiii. 270 (18S8). Also Mexican, and of 

 recent discovery, though first collected bj Mr. Alplionse

28. L. LATHYRoiDES. HosQclda laihjjroides, Dur. & Hilg, 

 Pac. R. Rep. v. 6. t. 3 (1853). An excellent species of the 

 southern part of California. Perhaps somewhat rare ; at 

 least seldom collected. We have it recently from Dr. A. 

 Davidson, who finds it near Los Angeles.
