The type is no. 7725, collected April 20, 1905, at Sunset, 

 Kern county, California, on dry gravelly hillsides. It is a pecu- 

 liar species, a true Platycarpos^ but not closely related to any 

 hitherto described. The lower horizontal branches are pros- 

 trate, resting on the ground. The dense flower spikes resemble 

 somewhat those of L. liiteolus^ but are much shorter.
