PHACELIA FAMILY 259 



Sierra Nevada. The transmontane representation tends on the whole to approximate in some 

 particulars that of coastal Southern California. Sometimes, at mdely scattered stations, the 

 stems are markedly woody at base (var. suffrutescens Parry), a condition that is a matter of age 

 (field observation by F. W. Peirson) and is not definitely and consistently associated with any 

 other feature.

A form growing in Southern California vfith the stems more hispid and puberulent (var. sub- 

 sinuata Mcbr.) is illustrated by: Mohave Eiver headwaters. Parry 4" Levimon 262; Playa del 

 Rey, Los Angeles coast. Parish 11,870 ; Newport Bay, Booth 1060. From this form there are 

 numerous shades of intergradation to usual forms of the species in which the stems are markedly 

 hispid to scantily hispid or merely puberulent or subglabrous. 



Tax. note. — There seems to be no constant difference that is marked between Phacelia ramo- 

 sissima and P. distans save in habit and in duration. In most cases P. ramosissima has leaves less 

 finely divided than in P. distans and with more rounded lobes. The corolla-scales differ, although 

 in P. distans they are variable. In P. distans the scale is short vertically, about equaling the 

 lateral lobe of the scale (rarely twice as long in the form called Phacelia ammophila Greene). 

 In P. ramosissima the scale is elongate with its lateral lobe small. — E. F. Hoover.

22. P. umbrosa Greene. Stems slender, weak, branching, 1 to 1% feet high ; 

 herbage thinly or sparingly hirsutulose or subglabrous ; leaves ovate in outline, II/2 

 to 3 inches long, pinnate or pinnately divided into 5 leaflets or divisions, the leaflets 

 or divisions ovate, shallowly and incisely lobed to crenate, % to IV2 inches long, at 

 least the lower with petiolules ; racemes rather slender, mostly dense, elongated ; 

 calyx-lobes linear, acute, long-hispid ; corolla white, tubular-campanulate, II/2 to 

 2^2 lines long, shorter than or barely equaling the calyx-lobes; corolla-scales broadly 

 united below, strongly dilated upwards ; seeds 4, densely papillate. 



Desert flats or slopes, 500 to 1500 feet : southwestern Colorado Desert. South 

 to northern Lower California. July. 



Tax. note. — Phacelia umbrosa is nearly related to P. distans. Almost nothing is known of 

 its ontogeny. While it has been once collected mthin the limits of California, namely, in the south- 

 western Colorado Desert by C. E. Orcutt, no exact station is known for it. In southern cismontane 

 San Diego County there appear to be forms of Phacelia distans which simulate P. umbrosa in 

 flowers and somewhat in leaves, as at Descanso.

23. P. distans Benth. Stem erect and strict, or branching and diffuse, 8 to 23
