PACHYPHYTUM LONGIFOLIUM 
Long-leaved Pachyphytum 
Native of central Mexico 
Family CRASSULACEAE OrPINE Family 
Pachyphytum longifolium Rose; Britton & Rose, N. Am. Fi, 22: 12. 1905. 
The simple stems are usually short, very leafy, mime it by 
an elongate raceme, the pink corollas nearly hid under the 
leafy bracts and leaf-like sepals. The leaves are elongate, Wen: 
fleshy and turgid, but somewhat flattened, two to three inches 
long, one ashe to three fourths of an inch broad, pre fourth to 
inch thick, narrowed from below the acute apex to 
the base ek int o short round petioles, glaucous, tinged with 
purple, the lower ones oe at right angles to the stem, the 
upper one; erect. The flowering raceme is six to ten inches ssi 
erect below, nodding aie leafless except just below the flow 
The large flowering bracts ee at the base, arranged in in 
h 
two rows, at first imbricate pals are large, origina! the 
two outer ones nearly equal, age! oblong, about ha inch 
long, the three inner ones smaller. The corolla is much s 
nailer 
than the calyx, about two-fifths of an inch long, pale on the outside, 
red on the inside. ‘The five we! distinct petals are erect below, 
spreading above, broad and rounded at apex but with a short 
abrupt point. The stamens art eet number, ae free and five 
borne on the petals, The five distinct carpels, each with a broad 
scale at its base, are erect, and each is terminated by a short style. 
The seeds are numerous, minute, oblong. 
This species is nearest Pachyphytum bracteosum, a well-known 
greenhouse plant, but has much narrower leaves. The foliage 
resembles that of the well-known garden plant, Echeveria clavi- 
folia, otherwise quite distinct. This plant was introduced into 
e collections of the New York Botanical Garden through speci- 
mens collected in 1904 by C. A. Purpus, in central Mexico, but no 
definite locality was given. 
The species is easily propagated by seeds or cuttings, and the 
leaves will give off new plants from their bases when put into the 
cutting-bed or even allowed to lie on top of the soil where they 
drop from the plant. 
Pachyphytum, known only from Mexico, and comprising sev 
described species, is characterized by very fleshy leaves, fase 
leafy sepals, rather thin petals, and curiously appendaged stamens,
