purpurei pulvillis 80-100 aculeolos capillares 6-12 obscuros lanamque longam cineream aaa dense stipato. 
Var. a. MINOR : aculeis brevioribus gracilioribus non aati floribus minori 
Var. 8. MAJoR: aculeis longioribus robustioribus intertextis ; floribas hacia 
Var. y. CASTANEUS : aculeis rubellis seu castaneis. 
From the Canadian near Delaware Mount, to the Rio Grande, and south to Monterey ; west not farther than the 
San Pedro River: flowers in May and June.— This species, now not rare in cultivation, seems to be sufficiently 
distinct from the preceding, and may always be recognized by the characters indicated. 
7.2 C. apustus, E. in Wisliz. Rep.: ovatus, 13-15-costatus; areolis ovatis seu ovato-lanceolatis; aculeis radiali- 
bus 16-20 adpressis albidis apice sdustia, Interalibus inferioribusque longioribus, summis setaceis brevissimis, centrali 
nullo seu valido porrecto atrofusco. 
ountains west of Chihuahua: flower and fruit unknown. — Echinocereus wsilenaag E., is the form with stout 
central spines 
8.? C. Rorisprnus, E. |. ¢.: ovato-cylindricus, 11-costatus ; areolis lanceolatis; aculeis radialibus 16-18 
adpressis intertextis, lateralibus eentenis multo longioribus fuscis recurvatis, centrali singulo valido fusco porrecto ; flore 
infundibuliformi, tubo subelongato, limbo patulo ; cient 8 tenuibus albidis. 
Mountains west of Chihuahua: flowers in May.— Stem 4 inches high; radial spines 4-9 lines, central one about 
an inch long. Flower different from that of all other Bchinoceret in the length of the tube (over 2 inches long and 
half as wide) and the whitish stigmata. Seems to form a transition to other sections of the genus 
9.? C. Lonersetus, E. in B. C. R.: subsimplex, ovato-cylindricus; costis 11-14 tuberculatis ; areolis 
orbiculatis ; aculeis setaceis albis, radialibus 18-20, centralibus 5-7, quorum 3 inferiores elongati deflexi. [281] 
Santa Rosa, south of the Rio Grande. — Stem 6~9 inches high ; tubercles well marked ; lower radial 
spines 5-7 lines long, much longer than the upper ones ; lower central spines 1-2 inches long. Flower said to be red.

10. C. Fenpuert, E. in Pl. Fendl.: ovato-cylindricus ; costis 9-12 ; areolis subconfertis ; aculeis basi bulbosis, 
radialibus 7-10 rectis seu curvatis albidis et fuscis, inferioribus robustioribus, centrali valido sursum curvato atrofusco 
sg elongato ; floribus sub vertice lateralibus magnis ; seminibus obliquis tuberculato-scrobiculatis. 
w Mexico, from Santa Fé to below El Paso, and from east of the Pecos to Zuni: flowers in May and June. — 
Stems $8 inches high, not many from the same base ; spines very variable, but always very bulbous at the base, and 
some of them white, some deep brown or black, and others party-colored ; radial ones 3-1 inch, and the central one 
1-2 inches long. Flower 23-3} inches in diameter, of a deep purple color. Berry 1-1} jocks long, edible. Seed 
asad and irregularly pitted by the confluence of many of the tubercles, unusually oblique. 
1.2? C. Mosavensis, E. & B. in P. R. R.: ovatus, dense czespitosus, glaucescens, 10-12-costatus ; areolis remo- 
tis ; pe validis curvatis, radialibus 7-8, lateralibus robustioribus longioribus, centrali singulo sursum curvato 
elongato. 
Var. 8.2? Zonrensts : 10-costatus ; aculeis debilioribus 4-angulatis bulbosis rectis vel flexuosis, radialibus 8, 
summo — robustiore ; centrali recto seu sursum curvato longiore, omnibus bul 
e Mojave River in California, and £. farther east, on the Colorado Chiquito. aoe heads 2-3 inches high, 
forming a. caespitose masses ; upper and lower spines 9-15 lines, lateral ones 15-25 lines long, central spine 14-24 
inches sone dusky. Var. f. is distinguished by having the upper radial spine almost as stout and long as the central 
spine, the former being 12-18, the latter 18-24 lines long. Both seem to be distinguished from the nearly allied 
C. leri by having the lowest spines weakest, while in that species they are the stoutest of the exterior ones. 
The resemblance to C. Fendleri induces me to place this species here, though the flower remains unknown. [282] 
. C. ENNEACANTHUS, E. in Wisliz. Rep.: ovato-cylindricus, viridis, ceespitosus, 7-10-costatis ; aculeis 
rectis, a 7-12 (plerumque sub-8) albis, inferioribus longioribus ; gentrali singulo (rarius 2-3) basi bulboso 
teretiusculo seu compresso angulato albido vel stramineo ; ovario pulvillis 25-35 aculeolos 6-12 gerentibus stipato ; 
seminibus tuberculatis, 
In the Rio Grande valley from El Paso to Laredo, and lower down, and far into Mexico: flowers April and May.— 
A very cxspitose plant, of a wrinkled or withered appearance ; 3-6 inches high ; spines above 3-5, below 8-16 lines 
long ; lateral ones intermediate; nemo spine extremely variable, in smaller specimens terete, in very perfect ones 
elongated, flattened, 8 or 10-15 or 20 lines long. Flowers 2-3 inches long and equally wide: ovary and tube covered 
with numerous bunches of teak: Fruit about an inch long, edible.
