A leafy-stemmed, fleshy plant. The stems are up to a foot 
long, one to one and one half inches thick, and very leafy through- 
. The leaves are thick, stiff, flattened, the lower ones standing 
at right angles to the stem, the upper ones erect or curved with 
ascending tips, purplish or bluish green, glaucous, oblanceolate, 
two inches or more long, acutish, terete at the base. The flowering 
stem is elongate, simple, eight inches to two feet long, naked below 
but leafy above, strongly curved at the apex, secund; the bracts 
than the others, broadly oblong, obtuse, about a third of an inch 
long; the upper sepal and the two lower ones are much smaller. 
e corolla is about a fifth of an inch long, dark red, its five lobes 
spreading, and free nearly to the apex. the ten stamens the 
five alternating with the petals are free from the corolla, the other 
five borne on the petals, each with a pair of appendages at its base. 
The five carpels are free to the base, erect, each with a broad scale 
at its base. 
This illustration is based on specimens obtained from Fairmount 
Park, Philadelphia, Pennsylvania, in 1900, which flowered in the 
New York Botanical Garden. 
This is a well-known greenhouse plant, often passing as Cotyledon 
Pachyphytum or as Echeveria Pachyphytum, but is abundantly 
distinct from both Cotyledon and Echeveria. Pachyphytum longt- 
folium has been already illustrated in this work at plate 4.
