Echeveria turgida Rose, in Britton and Rose, N. Amer. Fl., vol. 22, p. 21, 1905; op. cit, vol. 22, p. 538, 1918; J. A. Purpus, Monatscht. Kakteenk., vol. 17, p. 148, 1907; Poellnitz, in Fedde Repert, vol. 39, p. 243, 1936.

Illustrations. Monatscht. Kakteenk., vol. 17, p. 149, 1907; Moeller's Deutsche Gartenztg., vol. 26, p. 80, 1911.


Rosettes stemless, becoming cespitose; leaves numerous, crowded, upcurved to apex, flat, evenly turgid to the edges, slightly convex beneath but only faintly keeled just below apex, oblong-cuneate, at apex truncate and mucronate, to 5 cm. long and 25 mm. broad; inflorescences two to four, simply secund-racemose; peduncle erect-ascending, to 20 cm. tall, 2 to 3 mm. thick below; bracts few, appressed, oblong-ovate, acute, to 10 mm. long; flowers to 10 or more; pedicels slender, to 12 mm. long; sepals unequal, longest to 10 mm. long, wide­ly spreading, deltoid- to linear-lanceolate, acute; corolla cylindroid-conical, to 12 mm. long, 7 mm. in basal diameter; petals slightly spreading at tips; nec­taries lunate, to 2 mm. wide. Flowers from April on. Description from ma­terial long cultivated in California gardens.


Color. Leaves biscay-green, strongly pruinose, at edges and mucro Hays-russet; peduncle corinthian-red above; bracts light bice-green, to light jasper-red at tips; sepals as the bracts; corolla geranium-pink; petals deep-chrome within; styles light viridine-yellow.


Type. Collected near Viesca, Coahuila, Mexico, C. A. Purpus, 04/R-05.962 (US, no. 399652); Walpole nos.107, 108, unpublished.


Occurrence. Mexico. Coahuila; Viesca, not known from any other locality.


Collections. Mexico. Coahuila; Viesca, Purpus, 04/R-05.962 (type, US). Cultivated: Strybing Arboretum, Golden Gate Park, San Francisco, from Mrs. Dodson, E. Walther in 1958 (CAS); Soldena, Floyd, 36/ (BH).


Remarks. Plants grown in California agree perfectly with Walpole's watercolor, and undoubtedly are clonotypes. Echeveria turgida is readily distin­guished in its flattish but thick-edged, pruinose, obtuse, and mucronate leaves, long pedicels, and long widely spreading sepals. It somewhat resembles E. pumila var. glauca, but is much more pruinose, its leaves have thick edges, and both pedicels and sepals are relatively longer.
