quite as long as those of the globose or oblong rosettes at the base of the stem, 

 .•ill when dry delicately 1 ml rathei conspicuously aerved; sepals short, triangular, 



acute; petals yellow, narrowly lanceolate, acuminate, 3 lines long; follicles 

 broad, abruptly divergent from tin" united bases. 



Gabilan Peak; Mi. Hamilton; Marin Co.; Mendocino Co. Rarely collected. 

 Annual, ace. to Greene, and propagating by deciduous buds formed in the axils 

 of tli." lowest leaves. 



3. S. pumilum Benth. Annual; branching from just above the base, or 

 sometimes simple, 2 to 4 in. high, very slender; leaves 1 to 2 lines long, ovate- 

 oblong; flowers shortly pediceled or sessile, the branches of the cyme mostly 2 or 

 3; sepals minute, triangular; petals linear-oblong, acute, 1 to l 1 /^ lines long; 

 follicles short, filled by the single seed. 



Upper Sacramento Valley (Sierra Nevada foothills and the Marys vi lie 

 Buttes) ; Napa Range, low hills. 



3. COTYLEDON L. 



Stout perennial herbs; leaves very thick and fleshy, the basal ones in a 

 conspicuous rosette; leaves of the flowering stems mostly bract-like, narrowly 

 lanceolate, or the upper broader and shorter, all commonly with a broad inverse- 

 ly V-shaped clasping base. Flowers large for the group, yellow or reddish, 

 disposed in long racemes or secund cymes. Petals more or less united at base. 

 Follicles erect or suberect. — In appearance very similar to Sedum. (Greek 

 kotule, a shallow cup, the leaves forming a cup.) 



Cynic more or less flat-topped; leaves broad. 



Petals oblong-ovate or oblong, acute; pedicels 1 or 2 lines long 1. C. farinosa. 



Petals oblong-lanceolate or lanceolate, acute; pedicels unequal, 2 to 6 lines long or more. 

 Petals indistinctly winged on the back; cyme loose, often contorted; plant in age 



straw-colored 2. C. caespitosa. 



Petals distinctly winged on back; cyme compact; plant reddish 3. C. plattiana. 



Cyme with 2 to 4 racemose divisions; pedicels mostly 1 to 2 lines long. 



Inflorescence of simple secund racemes 4. C. lax a. 



Inflorescence more elongated and paniculately branched 5. C. setchcllii. 



1. C. farinosa Baker. Acaulescent; usually densely mealy, 5 to 8 in. high; 

 leaves oblong-lanceolate, acuminate, the larger ones of the rosette 2 to 3 in. 

 long; cauline leaves bract-like, broadly lanceolate, 1 in. long or less, the upper 

 very short; cyme rather flat and broad, or with several small supplementary 

 branches below and thus disposed to be somewhat paniculate; pedicels 1 or 

 2 lines long; petals oblong-ovate or oblong, acute, 3^ to 4 lines long. 



Pacheco Peak, Brewer. Very closely allied to the next. 



2. C. caespitosa Haw. Acaulescent, the short caudex l 1 /. in. thick or 

 less, with reddish flesh; herbage glabrous, the younger leaves in the center 

 ■ if rosette glaucous, the stems and inflorescence disposed to become straw- 

 yellow in age; rosulate leaves 2 to 5% in. long, either narrowly oblong (6 

 to 9 lines broad) or strongly dilated above (1% in. broad), all with con- 

 spicuously acuminate or lanceolate-acuminate apex; cauline leaves narrowly 

 Lai olate and bract-like, 1% in. long or less, the upper very short and tri- 

 angular; cyme compound, rather loose and sometimes few-flowered, 1\U to 3 

 in. high, the whole inflorescence or one side frequently flexuous- or recurved- 

 contorted; pedicels 2 to o' or even 12 lines long; calyx-lobes ovate, acute, nearly 

 2 lines long; petals orange or yellow, oblong-lanceolate, 4 to G lines long, 

 indistinctly winged on the back, fleshy in anthesis, afterwards becoming thin 

 and Bcarious.
