14. E. polycephaltts, E. & B. in P. R. R. : ovatus seu demum 
cylindricus, e. basi ramosus ; costis 13-21 acutis; aculeis robustis 
compressis annulatis plus minus curvatis rubellis, radialibus 4 - 8, in¬ 
fimo deficiente, superioribus (si exstant) gracilioribus; centrdlibus 4 
angulatis compressis, superiore latiore suberecto vel sursum tfurvato, 
inferiore longioi^ decurvo ; floribus flavis dense lanatis ; bacca sicca ; 
seminibus magnis angulatis. 
On the Mojave, Colorado, and Gila Rivers: fl. February and 
March. — Single only when young, forming bunches of 20 - 30 cy- 
lindric equal-sized heads when older; the largest seen were 2 - 2| 
feet high and about 10 inches in diameter. Exterior spines 1-2, in¬ 
terior ones 1| - 3|, inches long. — Shape very much like the last, 
but the flower very distinct. * 
15. E. Parryi, E. in B. C. R. : simplex, globosus vel depressus ; 
costis 13 acutis ; aculeis robustis angulatis annulatis albidis, radialibus 
8-11, rectis s. paullo curvatis superioribus gracilioribus, infimo defi¬ 
ciente, centralibus 4 paullo longioribus robustioribus, infimo longiore 
decurvo; bacca sicca dense lanata. 
West and southwest from El Paso. — Plant always single ; largest 
specimens 8-12 inches high by 10 - 15 in diameter. — Very similar 
to the last; but apparently distinct by the manner of growth and the 
white spines. Unfortunately, no seeds were collected. 
16. E. horizonthalonius, Lem., var. centrispinus, E. in B. C. R.: 
glaucus, depressus seu demum ovatus ; costis 8 obtusissimis latissimis ; 
areolis orbicularis basi truncatis; aculeis robustis compressis annulatis 
reCurvatis rubellis demum cinereis, radialibus 5-7 superioribus de- 
bilioribus, infimo deficiente, centrali singulo robustiore decurvato; 
floribus purpureis dense lanatis ; bacca sicca lanata ; seminibus mag¬ 
nis angulatis. 
From Donana, above El Paso, to the Pecos, and southward: fl. 
April and May. —Plant 2-8 inches high and 3-6 in diameter; 
spines f - 1| inches long,' nearly equal. Flower 2| inches long, but 
partly enveloped in dense wool. The original E. horizonthalonius is 
said to have no central spine, and linear-lanceolate acuminate pale 
rose-colored petals: in our plant the petals are, oblong-lanceolate and 
obtuse.
