 apex but tipped by a strong mucro (rarely? with one or two lateral teeth), the mucro and

Acaulescent or in age shortly caulescent. I^eaves forming rather open rosettes, usually 

 ascending, pale, glaucous, oblanceolate, 4-6 cm. long, 15-22 mm. broad at widest point, 

 strongly mucronate ; inflorescence a secund raceme ; flowers 7-12 ; sepals broadly ovate, 

 obtuse ; corolla about 12 mm. long. 



Collected by J. N. Rose and Jos. H. Painter near Toluca, Mexico, September 4, 1903 {no. 6818). 



37. Echeveria elegans Rose, sp. nov. 



Leaves numerous, in cultivated specimens 80-100, in wild specimens fewer and smaller, 

 in both forming a very compact rosette, very glaucous, of a pale bluish-green color, very 

 turgid, the margins translucent or in wild- specimens reddish, 3 cm. long in wild speci- 

 mens to 5-6 cm. in cultivated specimens, 2.5 cm. broad near the apex, rounded at apex, 

 except the central ones, and these mucronate-tipped. Flowering branches 10-20 cm. long, 

 pinkish, with 8-12 pinkish leaves ; flowers 5-7 in a secund raceme ; sepals bright-colored, 

 very unequal, often toothed near the base, ascending, not appressed to the corolla; buds 

 broadly oblong in outline, acutish ; corolla 10 mm. long, its segments distinct nearly to the 

 base, pinkish with yellow spreading tips, but connivent in age ; stamens all borne on the 

 corolla, attached just above its base, y^ its length ; scales broad ; carpels distinct, tapering 

 into slender styles. 



Collected by J. N. Rose in the mountains above Pachuca in 1901 and flowered in Washington, 

 February, 1904 {no. 960 ^ type) ; collected again in 1903 at the same locality {no. 737). 



3^> Echeveria simulans Rose, sp. nov. 



Very similar to E. elegans, but rosettes flatter, the leaves at most spreading, never 

 reflexed, thinner especially in the upper half ; numerous, somewhat mucronate. Flowering 

 branches at first nodding, becoming erect, pale below, pinkish above ; stem-leaves linear, 

 small and bract-like ; sepals pinkish, unequal, narrow, acute, appressed to the corolla ; 

 corolla narrow, the base rose-colored, the tips of the lobes and inner surf ace yellow ; carpels 

 more or less spreading when mature. 



Collected by C. G. Prinprle in a canon near Monterey, Mexico, in 1903 : flowered in Washington 

 in 1904 and 1905 (Rose no. 768). 



It differs from E. elegans in habit and leaves, as mentioned above, has a narrower corolla, and 

 narrower and more appressed sepals.

 inflorescence composed of small cymes, single flowers and twinned flowers arranged in a

 spreading, ovate, acute, separated nearly to the base, greenish-yellow spotted with red. 



Type locality : Near Tehuacan , Puebla.
