^18 PITTONIA. 



Very common in middle California, but only at consider- 

 able elevations in the mountains. Plentiful on Mt. Hamilton 

 and in the higher mountains south of Tehachapi. Distin- 

 guished from M. elegans, with which it has -long been con- 

 founded in all our books, not only by its different habit, 

 absence of all glandular hairiness, small heads, brown achenes, 

 etc., it is as strictly vernal (April to June) as M. elegans is 

 autamnal (Sept. to Nov.). The distribution of the two is also 

 ditferent ; M. elegans being confined to the neighborhood of 

 the sea, or low valleys among the mountains of the interior 

 Tlie Oregonian Madia coeymbosa {Madaria corymhosa, 

 DC. 1. c), frequent in the mountains of northern California, 

 a smaller, less hairy and somewhat glandular species, also 

 vernal, is without doubt distinct from both the others. 



Pentstemon Sonomensis. Suffrutescent and evergreen, 

 about a foot high, slightly puberulont: leaves rather light 

 green, coriaceous, obcordate, mucronulate, denticulate, about 

 a half-inch long and nearly as broad, very shortly petiolate, 

 the uppermost round-ovate, acutish : raceme terminal, sessile: 

 calyx-lobes lanceolate, acuminate. : corolla 1 inch long, deep 

 red, the segments nearly equal, apparently not widely spread- 

 ing : anthers slightly exserted, white-woolly.
