ECHINOCEREUS. 
23 
Type locality: Hills near San Jose del Cabo, Lower California. 
Distribution: Southern end of Lower California. 
This species was first collected by Mr. T. S. Brandegee near San Jose del Cabo, Lower 
California, in April 1897, and described by Mrs. Brandegee in 1904 as a new species of 
Cereus of the subgenus Echinocereus. 
In 1911 Dr. Rose re-collected it in some abundance at the type locality, and living 
plants were grown in the cactus collections in New York, Washington, and St. Louis. So 
far as we are aware it is not offered in the trade and is rare in living or herbarium collections. 
It has been collected in recent years also by Dr. C. A. Purpus and the name Echinocereus 
sciurus was incidentally used in referring to his collection (Monatsschr. Kakteenk. 14: 130. 
1904).

California, in 1911.

Growing in patches 6 to 12 dm. broad, branching at base, the stems ascending to about 3 dm.; 
ribs about 12, not very prominent, obtuse; areoles rather scattered, orbicular; spines white or pale, 
straight, rough, 1.5 to 2 cm. long; radials about 10; centrals 3 or 4; flowers, including ovary, 6 to 8 
cm. long, the tube very short; scales on ovary and tube small, acute, their axils crowded with short 
white wool and 6 to 8 long white bristles; inner perianth-segments, when dry, deep purple, 3 to 4 cm. 
long, obtuse; stamens short; fruit not seen. 
Type locality: Mexico. 
Distribution: Central Mexico. 
Cereus aciniformis (Pfeiffer, Enum. Cact. 101. 1837) is only a garden name supposed 
to be the same as Echinocereus cinerascens var. crassior (Rumpler in Forster, Handb. Cact. 
ed. 2. 787. 1885). 
Echinocereus deppei, unpublished, belongs here according to Schumann (Monatsschr. 
Kakteenk. 5: 123. 1895). Echinocereus cirrhiferus monstrosus is an abnormal form. 
Echinocereus glycimorphus was described from a sterile plant of unknown origin, 
obtained of F. A. Haage jr. of Erfurt; it was redescribed by Schumann, who cites definitely 
Mathsson’s plant from Hidalgo between Ixmiquilpan and Cardonal, but whether this 
latter plant is the type or not is uncertain. Schumann made for it a subseries Oleosi of 
which it is the only species. 
We feel justified in reducing E. glycimorphus to E. cinerascens; we have living plants 
of both from the Berlin Botanical Garden and they must represent essentially the same 
species,- while the differences pointed out by Schumann seem trivial. Not only have we had 
Echinocereus cinerascens from various authentic sources, but Dr. Rose has repeatedly 
obtained it from the Valley of Mexico and adjacent regions. The plant is of wide distribution 
and has been reported from farther south than any of the other species of this genus. 
Echinocereus undulatus Hildmann (Schumann, Gesamtb. Kakteen 261. 1898) is only 
a catalogue name for it.
