5. C. rawsoniana Greene. Lady Collomia. Stem simple or with a few short 

 branches above, very leafy, 1 to 2 feet high, arising from a slender horizontal root- 

 stock ; leaves all cauline, the blades ovate to oblong-lanceolate, coarsely and incisely 

 serrate or entire towards the base, rather thin, viscid-pubescent, 1 to 2^/2 inches 

 long, narrowed below to a sessile base ; calyx 4 to 414 lines long, its lobes narrowly 

 lanceolate, longer than the tube, the tube uniformlj' chartaceous; corolla orange, 

 turning pinkish 011 drying, narrowly funnelform, 1 to 1^/4 inches long, 4 times as 

 long as the calyx, its lobes 4 to 5 lines long, its throat longer than the tube ; stamens 

 exserted, the filaments equally inserted at the base of the corolla-throat; capsule

Montane, 4000 to 7000 feet : Sierra Nevada in Madera Co. Aug. 



Geog. note. — Collomia rawsoniana is an extremely narrow endemic. It was first discovered 

 in 1888 by L. A. Rawson Peckinpah in Madera County, undoubtedly at or near Cascade! ranch, 

 which is on the drainage of a tributary of North Fork San Joaquin River and about 3% miles east 

 of Northfork station. Aside from the Northfork district it is known only from Bcasore Mdw., 

 Madera Co. (Margaret Hyan), which is on the headwaters of Beasore Creek, a branch of Chiquito 

 Creek which flows into the San Joaquin River. As at present known it has a longitudinal range 

 of about fifteen miles.

6. C. larsenii Payson. Stem simple or branched from base, 1 to 6 inches high, 

 arising from a slender deep-seated rootstock, the thickish leaves crowded on the 

 stems at the surface of the ground and forming dense tufts ; herbage finely villous ; 

 leaf -blades orbicular in outline, 2 to 4 lines long, once or twice palmately divided 

 into linear or obovate lobes, the petioles 1 to 5 lines long; flowers in a loose terminal 

 cluster; calyx-lobes lanceolate, twice as long as the tube, the tube uniformly sub- 

 membranous; corolla blue or violet, narrowly funnelform, 7 to 8 lines long, 2 to 3 

 times as long as the calj-x ; stamens unequal, equally inserted on the lower part of 

 corolla-throat, the longer equaling the corolla ; style equaling corolla or slightly 

 exserted; capsule cells 1-seeded. 



Loose rocks of volcanic peaks, 9000 to 10,400 feet, rare : Lassen Peak. North 

 along the Cascade Range to Washington. July-Aug. 



Geog. note. — Collomia larsenii is known in California only from the summit of the volcanic 

 cone of Lassen Peak, where it was discovered by J. G. Lemraon and his companion, John Larsen, 

 a frontiersman, in September, 1874. V. K. Chesnut and E. R. Drew obtained it on their climb of
