C. ATROPURPUREA, Baker. Breviter caulescens, glabra, foliis dense rosu- 
latis atro-purpureis glaucis obovato-spathulatis ultra duplo longi- 
oribus quam latis acutis dimidio inferiore spathulatim angustatis, 
ramorum floriferorum confertis valde reductis, floribus 20 —25 sub- 
laxe eequilateraliter racemosis, bracteis linearibus pedicellis patenti- 
bus subequantibus, sepalis lanceolatis equalibus patulis corolla 
saturate rubra distincte pentagona subtriplo brevioribus.—E'cheveria 
atropurpurea, Hort. 
Probably a native of Mexico. 
Stems glabrous, attaining a height of four to six inches and a 
thickness of an inch. Leaves about twenty, aggregated in a 
dense rosette, obovate-spathulate, the largest four to five inches 
long by two inches broad three-quarters of the way up, acute, the 
base broad for the genus, the texture moderately thick, the upper 
surface especially dark purple with a glaucous bloom. Stem 
erect, about a foot high without the raceme, its leaves close, 
much reduced. Raceme twenty- to twenty-five-flowered, five to 
six inches long when fully expanded by less than two inches 
broad. Bracts linear, the lowest half an inch long. Pedicels 
three-eighths to half an inch long, spreading horizontally or in 
the lowest a little deflexed. Sepals subequal, patent, linear- 
lanceolate, two lines long. Corolla bright red, half an inch deep, 
decidedly pentagonal, the divisions acute, the outer row of 
stamens inserted about half-way down. 
Nearest C. canaliculata (Mon. No. 9), but the leaves much 
broader and spathulately narrowed in the lower half, the colour 
characteristic, and the calyx and corolla much smaller.

3, carpels and hypogynous scales: all magnified.—J. G. B. 
I received this interesting and beautiful species, of the section 
Echeveria of the genus Cotyledon, from Mons. De Smet, of Ghent. 
I am not aware of its native country. It requires the same treat- 
ment as the species figured at Tab. 197.—W. W. S.
