STONE- CROP FAMILY 107 



Shallow sterile red or yellow clay loam, usually underlaid with hardpan, lower 

 foothills or mesas, 50 to 2000 feet : coast line of Southern California from San Luis 

 Obispo Co. to San Diego Co. May. 



Cultural note. — "I have collected specimens of H. variegatus from the following localities: 

 La JoUa; Las Flores, near Oceanside; Pt. San Juan, Orange Co.; Pt. Sal, Santa Barbara Co. 

 These plants, I find, differ from each other only in vigor, all having white flowers (not yellow 

 as usually described). I transplanted some plants of Hasseanthus variegatus from La Jolla to 

 red clay loam in my garden at Los Angeles, gave them plenty of water and a warm location, and 

 they became identical with Hasseanthus blochmanae Eose." — T. W. Minthorn, May 24, 1929.

 stem leaves similar to those of no. 1, but usually narrower; petals greenish-white 

 to light greenish-yellow, variegated, more united at base than in no. 1, erect below

5. RHODIOLA L. 



Perennial herbs. Stems several from a short scaly caudex crowning a stout 

 root. Leaves flat, comparatively thin, distributed equally up the stem, not in 

 rosettes. Flowers dioecious or polygamous, borne in a very dense cyme, the 

 branches not secund. Sepals and petals usually 4 and stamens 8. Petals in ours 

 dark purple, spreading a little. Carpels erect, dark purple. — Species 12, north 

 temperate and arctic zones. (From Greek rhodon, a rose, referring to the rose- 

 scented roots.) 



1. R. rosea L. var. integrifolia Jepson. Western Roseroot. Stems erect, 

 3 to 6 inches high ; leaves ovate to oblong-ovate, entire or obscurely dentate, sessile 

 by a broad base, 5 to 12 lines long, 2^2 to 4 lines wide, green; flowers 1% to 2% 

 lines long. 



Alpine, 9500 to 12,500 feet : Sierra Nevada from Tulare Co. to Eldorado Co. 

 North to Alaska, east to the Rocky Mts. June-July. 



Tax. note. — The chief difference between the European Ehodiola rosea L. and the west 

 American form of it resides in the pistillate flowers. The pistillate flower in western plants is 

 very fleshy and has larger and thicker calyx-lobes than in case of the European plant.
