CRASSULACEiE. 



narrowly lanceolate, acuminate, 3 lines long; follicles broad, abruptly- 

 divergent from the united bases. 



Summit of Gabilan Peak, Monterey Co., Brewer; Mt. Hamilton, 

 Greene; and northward to Marin Co., Congdon; Mendocino Co., 

 Chesnut and Ih-ew. Karely collected. Annual, acc. to Greene, and 

 propagating by deciduous buds formed in the axils of the lowest 

 leaves. 



3. S. pumilum Benth. 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 1£ lines long; follicles short, filled by the single 

 seed. 



Upper Sacramento Valley (Sierra Foothills and the Marysville 

 Buttes); low hills bordering Napa Valley on the east, Jepson, Apr., 

 1893. 



3. COTYLEDON L. 



Stout perennial herbs; leaves very thick and flesh} 7 , the basal ones 

 in a conspicuous rosette; leaves of the flowering stems mostly bract- 

 like, narrowly lanceolate, or the upper broader and shorter, all com- 

 monly with inversely triangular 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. Species difficult to elucidate, 

 the types not known to us and the existing diagnoses unsatisfactory. 

 The descriptions which follow have been derived from fresh material 

 and from herbarium specimens which have been segregated into 

 forms and the current names (with one exception) employed, with as 

 much judgment as was possible under the circumstances, for their 

 designation. (Greek kotule, a shallow cup, the leaves cup-like in. 

 some species.) 



Cyme 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. cxspitosa. 



Petals distinctly winged on back; cyme compact; plant reddish .... 



3. C. Plattiana. 



Cyme with 2 to 4 racemose divisions, or the branches more elongated, more 

 or less re-branched, and paniculate; pedicels mostly 1 to 2 lines long . . 



4. C. laxa. 



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 lanceo- 

 late, 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.
