Differs from typical L. concinnus only in being commonly more 
congested and with smaller flowers, 6-7 mm. long, banner nar- 
rower, about 3 mm. wide. 
My determination of Watson’s species is based upon the Gray 
Herbarium sheet of the only collection cited by him, while I have 
judged Jones’s species from his several specimens in the United 
States National Herbarium. I see no substantial differences 
between the specimens concerned, and Watson’s assignment of his 
species to the subgenus Platycarpos I cannot accept.
