128 BOTANY. 
with 21-25 rather sharp ribs; the large linear-oblong areole (very woolly 
when young) bear three kinds of spines, first, 4 very stout, annulated, reddish 
ones, 13-23’ long, the 3 upper ones straight, the lower one hooked; second, 
3-5 lower and usually 3 uppermost spines, slender, but straight, stiff, and 
annulated, of reddish color; third, 12-20 whitish, bristle-like, flexuous, 
lateral spines: flowers 2-24’ long, 14 wide, yellow, outside greenish with 
purple-brown; ovary and fruit imbricately covered with numerous (50-60) 
cordate or reniform crenulate sepals; sepals of tube oblong, ciliate; petals 
broadly linear, crenate, bristle-pointed; style deeply divided into 12-18 
linear stigmas; seeds 1” long or over, reticulate or shallow-pitted—Southern 
New Mexico. 
Var. Le Conter. (£. Le Contei, Engelm.)—At last clavate from a slender 
base; lower central spine more flattened, curved or twisted, but not hooked; 
flower rather smaller and with fewer parts—This is the Western form, from 
South Utah and Arizona to and beyond the Colorado River. Dr. Rothrock 
collected, at Camp Bowie, Ariz., a peculiar form (492), which may repre- 
sent another variety, decipiens: globose, 1° in diameter; spines shorter and 
fewer, no straight spines above the 4 central ones, none longer than 1-14 
inches; 10-15 thin flexuous spines on side and upper end of areole; only 
20-25 sepals on ovary. 
Ecurinocactus P tus, Engelm. & Bigel. (see Watson in Bot. 
King’s Expl.117)—From the Mojave region to Southwestern Utah. The 
numerous spiny-bristly sepals, and the linear, acute, yellow petals almost 
hidden in a dense cottony wool. 
Ecuinocactus Wuirrier, Engelm. & Bigel; Watson, J. c. 116.—On 
the Lower Colorado River and northward into Utah. 
Crrevs (Ecuivocerevs) Enerumanni, Parry; Watson, 1. c. 117.— 
Throughout Arizona and into Utah and Southern California. Flower 
purple, open only in mid-day sunshine-—Camp Bowie (1002), Mrs. Major 
Sumner. Flower only. May be this or an allied species. 
Cereus (Ecurnocergus) pua@niceus, Engelm.—Globose or oval heads, 
2-3' high, about 2’ in diameter, several to a great many (sometimes over 
100) from one base, 8-11-ribbed; 8-15 slender, but straight, stiff, and 
very brittle spines in each bunch, 4-14’ long, 1-3 of them more central and
