Distributed by J. Donnell Smith as Sedum bicolor (no. 3633) 
and Cotyledon Peruviana (no. 7308), from both of which it seems 
to differ. HH. Pittier has also sent abundant living material from 
San José, Costa Rica (December, 1902) from which the above 
description is drawn and which is taken as the type of the species. 
Echeveria maculata Rose, sp. nov. 
Acaulescent, glabrous throughout; basal leaves ina dense rosette, 
elongated-lanceolate, thickish, about 1 dm. long, 1.5-2 cm. broad, 
free nearly to the base, acute at tip and slightly spreading. 
Collected by J. N. Rose near Dublan, Hidalgo, Mexico, July 2, 
Ig0I (no. 5412), and sent to Washington where it has repeatedly 
flowered. 
This species is somewhat similar to &. mucronata, but is cer- 
tainly distinct. 
Echeveria platyphylla Rose, sp. nov. 
Acaulescent, glabrous throughout; basal leaves in a dense rosette, 
somewhat rhomboid in outline, thinnish, pale green, acuminate, 
tipped with a slender cusp, 4-5 cm. long, about 2 cm. broad; 
flowering branch 2-3 dm. long, bearing small scattered leaves be- 
low; flowers 15 to 20, arranged i in an equilateral raceme; pedicels 
less; sepals green, thickish, linear, erect, subequal ; 
corolla reddish yellow, lobes 9 mm. long, tips spreading even in age, 
tube very short, 1-2 mm. long. 
Collected living by J. N. Rose, Valley of Mexico, July, 1901 
(no. 6393). The specimens have frequently flowered in cultiva- 
tion at Washington. This species must be close to &. mucronata, 
but has very different foliage. The above description is drawn 
entirely from living plants. The Department of Agriculture has 
many seedlings for distribution. 
Echeveria tenuis Rose, sp. nov. 
Acaulescent, glabrous throughout; leaves fleshy, numerous, 
forming a flattened rosette, oblong, 4-5 cm. long, much narrowed 
at base, acute; flowering branches slender, at first nodding or scor- 
pioid, their leaves linear or at least narrow, with a small rounded 
spur at base; flowers sessile or nearly so; sepals very unequal,
