Cotyledon. CRASSULACE^E. 211 



besides those of California, which are still imperfectly known. These American forms belong to 

 the genus Echcvcria, DC. (now merged in Cotyledon), distinguished by the larger often foliaceous 

 calyx, and the terete or sulcate pitcher-shaped corolla more deeply parted. 



* Leaves terete : petals yellowisli, sjyreading : carpels divergent above t/ie united base. 



1. C. edulis, Brewer. Glaucous, nearly acaulesceut, the stem very short, thick, 

 and covered with the bases of dead leaves : rosulate leaves numerous, terete or 

 somewhat triangular, acute, dilated at base, the outer ones 3 to 5 inches long: 

 flowering stems a foot high or more, with similar scattered leaves an inch or two 

 long, the upper and Moral ones very small : inflorescence paniculate, the scattered 

 spreading branches 2 or 3 inches long: flowers nearly sessile : sepals ovate, acutish, 

 li to 2 lines long : petals united at base, narrowly oblong, 3 or i lines long, acute or 

 acuminate, widely spreading : carpels ovate-oblong, united above the base, divergent 

 above, 3 lines long : seeds rather few, linear-oblong, very acute at both ends, half a 

 line long. — Sedum edule, Xutt. in Torr. & Gray, Fl. i. 560. 



On dry banks near the sea at San Diego, Nuttall, Parry, Cooper, &c. The young leaves are 

 eaten by the Indians. A very peculiar species. 



* * Leaves flattened : carpels nearly distinct, erect. 



+■ Petals united to the middle, red : carpels linear : pedicels mostly horizontal. 



2. C. pulverulenta, Ik-nth. & Hook. More or less white-pulverulent through- 

 out : stem short and very stout : leaves rather thin and flaccid, in a flattened rosette 

 often a foot or more in diameter, broadly spatulate and very abruptly acute, becom- 

 ing l' to i inches broad and at length glabrate, the younger leaves very mealy and 

 in n v gradually acuminate : flowering stems 1J feet high or more, stout, with very 

 broadly cordate often approximate acute leaves, or the lower ovate and acuminate ; 

 floral bracts small : inflorescence of 2 to 6 elongated ascending simple racemes, usually 

 G t . 12 inches long; pedicels mostly horizontal, slender, 3 to 8 lines long: flowers 

 erect or ascending : calyx-lobes ovate, acute, 2 or 3 lines long: corolla narrow, sul- 

 cal . red ("pale-scarlet or coral-color") ; lobes oblong, acute: carpels G lines long: 

 sieds very numerous, smaller than in the last. — Echeveria pulverulenta, Nutt. in 

 Torr. & Gray, Fl. i. 560. 



Frequent in rocky ravines from the Sierra Santa Monica (Brewer) southward to San Diego, 

 Nuttall, Cleveland, Palmer. Eaten by the Indians. The figure of C ' . Baker, L c, 



I. 66, cannot be cited as :i r< i n of the typical form of the 8] ies. It is uncertain to 



what it should be referred. The Edit ocria pulverulenta and I'., lanccolala of Bot. Mex. Bound., 

 from the Corinados Islands near San Diego (Thurber), arc not satisfactorily determinable.

 ovate- to linear-oblong: pedicels ascending. 



3. C. lanceolata, Benth. & Hook. Glaucous, the leaves more or less densely 

 white-puberulent : stem very short, more slender than in the last : rosulate leaves 

 less spreading, lanceolate to ovate lanceolate, acuminate, the outer ones 2 to I inches 

 long : flowering branches \~> inches high or more, slender, the lower leaves lanceo- 

 late, becoming above broadly triangular-ovate, clasping, acute; the llor.tl bracts 

 much shorter than the pedicels : inflorescence in a compound cyme or often of 2 or 

 3 short simple racemes; pedicels 2 to I lines long: sepals triangular ovate, acute, 2 

 lines long: petals oblong, acute, I to G lines long, erect, reddish-yellow: carpels 

 linear-oblong, 5 lines long including the style: seeds oblong, acutish al each end, 

 a third of a line long.' — Echeveria lanceolata, Nutt. in Torr. >V Gray, 11. i. " I .
