 Candolle's illustration of a flowering branch, and perhaps not an Echeveria, 



Type locality : Mexico. 



Distribution : Known only from the type locality.

41. Echeveria retusa lyindl. Jour. Hort. Soc. London 2 : 306. 1847. 



Cotyledon retusa Baker, in Saund. Ref. Bot. 1 : sub pi. 64, no. 22. 1869. 



Acanlescent or nearly so, glabrous throughout. Leaves in a dense rosette, obovate to 

 spatulate, 7.5 cm. long; flowering stem 2 dm. long, leafy below; inflorescence a very com- 

 pact panicle ; sepals narrow, very unequal, shorter than the corolla ; corolla strongly 5- 

 angled, bright-red, 15 mm. long. 



Type locality : Anganguco, Michoacan, Mexico. 

 Distribution : Mexico. 

 Illustration : Bot. Reg. 33 : pi. 57. 



42. Echeveria rubromarginata Rose, sp. nov. 



Acaulescent or short-caulescent. Ivcaves few, about 12, stiff, ascending, oblanceolate 

 6-12 cm. long, narrowed to a short thick petiole, obtuse, mucronate, glabrous, glaucous 

 with somewhat crenulate margins ; flowering stems 5-12 dm. high, the lower leaves spatu- 

 late and obtuse, the upper ones ovate and acute; inflorescence paniculate, 1-2 dm. long-- 

 pedicels very short; sepals very unequal, the longer ones 8-9 mm. long, spreading, glau- 

 cous ; corolla pale rose-colored, 12 mm. long, a little paler within, the lobes acute, thick. 



Collected by C. A. Purpus on rock near Orizaba, Mexico, December, 1903 (Rose no. 930 type) 

 and also near Orizaba by Frank M. Meyer, June, 1904 (Rose no. 1015). This species seems nearest 

 E. retusa but it has different leaves, sepals, and corolla. 



43. Echeveria Lozani Rose, sp. nov. 



Acaulescent. Leaves forming a dense rosette, lying flat upon the ground, lanceolate 

 or strap-shaped, 10 cm. long or more, 2-4 cm. broad at widest point, flattened and rather 

 thickish except at the base, but here very thick and somewhat channeled, acute, glabrous 

 the central ones copper- colored ; flowering stems 3-4 dm. long ; inflorescence a short 

 panicle ; sepals unequal, ovate, acute ; corolla light copper-colored, the lobes acute. 



Collected by C. G. Pringle and his assistant Filamon L. Lozano in mountains near VfvatU-n 

 Jalisco, Mexico, October 27, 1903 {no. 11890). ntzauan,

Acaulescent, more or less purplish throughout, somewhat glaucous. Basal leaves in a 

 rather dense rosette, broadly lanceolate, acuminate, 5-6 cm. long; flowering branches 3^ 

 dm. high, strict, leafy below ; inflorescence at first very compact, more open in age, panic- 

 ulate, many-branched, its branches forming few-flowered secund racemes ; flowers very 

 short-pedicelled, the pedicels 1-2 mm. long ; sepals lanceolate, unequal, the longer ones 5-6 

 mm. long, acute; corolla red, 1 cm. long; corolla-segments united for one-fourth their 

 length, acute. 



Type locality ; Sandy_ slopes of mountains around San I^uis Potosi. 

 Distribution : San I^uis Potosi.
