pedicellate, the pedicel in fruit elongated and surpassing the leaves: 

 petals oblong, acutish, equalling the carpels, more than twice the length 

 of the ovate calyx-segments. Frequent on muddy shores about San 

 Francisco. May. 



2. SEDUM, Columna (STONE-CHOP). Glabrous perennials or annuals. 

 Flowers in cymes, mostly secund. Sepals 4 or 5, united at base. Petals 

 as many, distinct. Stamens twice as many. Carpels distinct, or rarely 

 connate at base, few- or many-seeded. 



* Perennial. 



1. S. spathulifolium, Hook. Glaucous and of ten pulverulent : stems 

 4 6 in. high, ascending from a branched and rooting caudex: leaves 

 flat, obovate or spatulate, obtuse, 610 lines long: fl. 3 lines long: petals 

 yellow, lanceolate, acute, twice longer than the ovate acute sepals. 

 Rocky places on the northward slopes of hills and mountains from San 

 Francisco and Berkeley northward. 



* * Annuals. 



2. S. radiatnm, Wats. Stems 36 in. high, decumbent at base: 

 leaves oblong or oblong-ovate, obtuse or acutish, somewhat clasping by 

 the narrower base, % % in. long: fl. sessile; sepals short, triangular; 

 petals yellow, narrowly lanceolate, acuminate, 3 lines long: carpels 

 broad, abruptly divergent from the united bases. Mt. Hamilton. Strictly 

 annual, though propagating by deciduous buds formed in the axils of 

 the lowest leaves. 



3. S. pumilnin, Benth. Slender, erect, 13 in. high: leaves 1 2 

 lines long, ovate-oblong: fl. sessile in sparingly branched cymos; calyx- 

 lobes minute, triangular; petals yellow, linear, acute, 1J lines long: 

 follicles short, 1-seeded, the seed erect, filling the cavity. Hills of Napa 

 Co. and eastward. 



3. COTYLEDON, Nicander. Succulent herbs coarser than Sedum 

 and larger, but quite like them in all other respects save that the petals 

 are more or less united into a tube, and the follicles erect or suberect 

 rather than spreading; the inflorescence in ours compound-cymose. 



1. C. ca'spitosa, Haw. Nearly or quite acaulescent, dull green: 

 leaves ovate-oblong to oblong-lanceolate, acute, the larger 1^ 3 in. 

 long: flowering branches J 1 ft. high, with broadly triangular-ovate 

 clasping bracts: pedicels short and stout, subtended by broad bracts: 

 sepals ovate, 2 lines long or less: petals yellow, broadly lanceolate, acute, 

 4 5 lines long: carpels ovate-oblong, about 3 lines long From near 

 San Francisco northward. 



2. C. farinosa (LindL), Baker. Short-caulescent, more or less white- 

 farinose: leaves rather flaccid, ascending, lanceolate, acuminate, the
