C. Fendleri, Engelm. Cactacee of Emory’s U. S.and Mexican Boundary Survey, 
34, tab. 52, 53, : 
This fine Cereus is a native of the great Cactus region of 
the United States, where, according to its author, Dr. 
Engelmann, it inhabits rocks in alluvial river-bottoms 
from Santa Fé to the Cafion of the Rio Grande below El 
Paso, and from fifty miles east of the Upper Peros west- 
ward to Zuni, and the Aztec mountains and the Copper 
mines. It is admirably described and figured along with 
twenty-eight other Cacteze from the same region in the 
work of Dr. Engelmann quoted above, whose characters I 
have nearly verbatim reproduced, finding that though 
drawn up (presumably) for dried specimens, they perfectly 
accord with those of the cultivated one here figured. 
Our specimens were presented to the Royal Gardens along 
with a very choice set of other Cactex from the same regions 
by Edmund Giles Loder, Esq., of Howe, Floore, a gentle- 
man who possesses a rich collection of rare succulent and 
other plants. It flowered soon after it was received in June 
of this year. | —
