ventral marfjrin witli a fringe of translucent gland-tipped liair-like processes, the 

 contiguous faces of the carpels also somewhat glandular with short hairs. Seed 

 one, slenderly spindle-shaped. — Species 1. (Diminutive of Sedum). 



1. S. pumila liritt. & Rose. Stems slender, 1 to 4 inches liigh, simple or char- 

 acteristical[\' with a few ojiposite or subopposite ascending branches of about 

 equal length and hence the plant often flat-topped; leaves few, 2 to 2^/2 lines long; 

 cyme with 2 or 3 racemose branches; petals yellow, oblong-lanceolate, 1 to lYo 

 lines long, spreading in anthesis but later becoming erect; sepals minute. 



Rocky or gravelly slopes in the foothills, 300 to 3000 feet : Sierra Nevada from 

 Fresno Co. to Tehama Co.; Napa Range. Apr.-June.

Var. congdonii Jepson. Styles ^4 line long or slightly more and commonly curved (in the 

 species the styles commonlj- straight and Y2 line long). — Southern Sierra Nevada foothills 

 from Mariposa Co. to Tulare Co. This form differs very slightly from the species and is 

 dubiously given varietal rank. The flowers do not differ in size from the species and appar- 

 ently do not differ otherwise. The following stations may be noted: Three Rivers (4 mi. e,

3. CONGDONIA Jepson 



Diminutive herb with very slender tuber-bearing rootstock. Stem simple, 

 scapoid, naked or with 1 or 2 inconspicuous leaves on the upper fourth, bearing a 

 single terminal erect flower. Leaves ovate, relatively thin, closely imbricated in 

 basal rosettes. Petals white, ovate, united for about % their length into a tube. 

 Carpels erect, several-seeded. Seeds rubescent. — Species 1. (J. W. Congdon of 

 Mariposa Co., acute-minded collector of the Sierran flora.) 



1. C. pinetorum Jepson. Stem very slender, I/2 to II/2 inches high; leaves 

 sessile, 1 to V/2 lines long; petals 11/2 to 2 lines long.

4. HASSEANTHUS Rose 



Stems one to several from globose or oblong corms. Leaves not in rosettes; 

 basal leaves and stem leaves somewhat unlike. Flowers white or greenish, in a 

 cyme, the 2 or 3 branches secund, widely spreading. Petals united at base into a 

 short tube. Carpels widely spreading. — Species 2, California. (Dr. H. E. Hasse, 

 local collector in the Santa Monica Mts., and Greek anthos, flower.) 



Basal leaves always with a distinct petiole; petals white, spreading 1. H. variegatus. 



Basal leaves linear or semi-cylindric, fleshy, never petioled; petals approximate by edges below to 

 form a false tube, spreading above 2. H. elongatus. 



1. H. variegatus Rose. Stems 1 to 6 in number, 4 to 9 inches high; corms 1 

 to 3 ; basal leaves only 3 to 5 in a season, obovate to oblanceolate, very fleshy, more
