25. L. eriophorus Greene. Mat Lotus. Steins several to many from the root- 

 crown, elongated, forming mats 1 to 5 feet wide; herbage gray- or rusty-villous; 

 leaves on the main branches 5 to 14 lines long, often conspicuously larger than 

 those on the secondary branches; leaflets 4 to 6, oblanceolate or obovate, acute and 

 apiculate, 3 to 9 lines long; umbels 4 to 8 (or 10) -flowered; flowers 2^/2 to 3I/2 lines 

 long; calyx slightly more than % as long as the corolla, the filiform teeth nearly as 

 long as the tube ; corolla yellow, aging deep red ; pods terete, arcuate, not keeled or 

 only slightly so, abruptly beaked, usually 2-seeded, the body 1% to 3 lines long, 

 the beak about as long. 



Flood beds of streams, alluvial valleys or sandy flats, 5 to 2000 (or 6500) feet:

 Simeon, T. Brandegee ; Colton, Dunn; Strawberry Valley, Mt. San Jacinto, Jepson 2288; San 

 Jacinto Eiver (e. of Florida), Jepson 1255; Palomar Mt., T. Brandegee. The var. heermannii 

 Ottley has a thinner pubescence (the stems often glabrate), smaller flowers (1% to 2i/^ lines 

 long) and often 1-seeded pods. These characters are, however, not always associated, so that the 

 variety is more or less indefinite. The following specimens may be cited as var. heermannii, 

 though some are nebulous between the species and variety : Soquel Creek, Santa Cruz Mts., Jepson 

 13,802; Tujunga Canon, near San Fernando, Ottley 692; Arroyo Seco, San Gabriel Mts., Peirson 

 99; Fish Canon, San Gabriel Mts., Peirson 510; Lytle Creek, San Antonio Mts., Ottley 712; San 

 Bernardino, Parish; Pabn Canon, San Jacinto Mts., Jepson 1362a; Devils Canon, Santa Rosa
