EOHINOCACTUS. A large genus of 

 some 200 or more species, among them 

 some of the most handsome and cur- 

 ious forms of plant life known. 



"Flowers about as long as wide. Ovary 

 covered with sepaloid scales, naked or 

 wooily in their axils. Fruit succulent or 

 sometimes dry, covered with persistent 

 calyx-scales, sometimes enveloped in co- 

 pious wool, and usually crowned with the 

 persistent remnants of the fiov/er. Seed 

 obliquely obovate, black. Embryo curved 

 over the small albumen; cotyledons par- 

 allel to the sides of the seed. Mostly 

 large, sometimes gigantic, globose or de- 

 pressed, or ovate, or rarely subcylindric, 

 simple or very rarely cespitose; Dunches 

 of spines on the more or less vertical ribs. 

 Flowers contiguous to and above the 

 spines, on the latest growth of the plant, 

 often from the nascent wooily areoiae 

 and therefore more or less vertical, open 

 only in sunlight." E. 

 ECHINOCACTUS CATAPHRACTUS. 



Dwarf, globose or depressed-globose: 

 ribs up to 10, with curious half-moon 

 shaped brown to violet blotches below 

 the areoiae: spines 5-7, straight or 

 somewhat curved, 7% -10 lines long, 

 bright golden; flowers produced in the 

 depression at the summit of the plant, 

 otherwise undescribed. Probably from 

 Paraguay. Introduced by E. Heese 

 (MfK 1904, 172). 

 ECHI]W?CACTUS CHRYSACANTHUS O. 



Globose to cylindrical, with about 18 

 ribs and 10 flexuous annulated central 

 spines 2 inches long, and 4 to many slen- 

 der white radial spines. Flowers satiny 

 yellow, more rarely crimson. Cedros Is- 

 land. 

 ECHINOCACTUS CUMINGII Hopff. 



Bolivia, South America. 

 VARIETY FLAVISPINA. 



Stem scarcely depressed at summit, 

 which is overtopped by yellowish 

 spines. Introduced by K. Hirscht 

 (MFK 1904. 77). 



K. cylindraceus. In 1852, in the 

 American journal of science, series 2, 

 14:338, Engelmann published this as 

 a questionable variety of E. virides- 



cens, stating that it was distinguished 

 by its oval or cylindrical shape, larger 

 size, and longer spines. It was found 

 near San Felipe, on the eastern slope 

 of the California mountains, by Dr. 

 C. C. Parry. Mature specimens are 

 usually 2-3 feet high and a foot or 

 more in diameter, cylindrical, simple, 

 with a woolly spineless depressed top 

 and 21-27 obtuse somewhat tubercu- 

 lated ribs, but one specimen observed 

 measured a little over ten feet high 

 and 3 feet in greatest diameter, and 

 occasionally specimens that have been 

 injured are found densely proliferous 

 at base. Young plants globose, 13- 

 ribbed, with spines often of an ivory 

 white, yellowish, or of a beautiful red- 

 dish color, or variously colored, but 

 in age all spines become yellowish, and 

 are stout, annulated, recurved or flex- 

 uous, the 4 centrals very stout, the 

 12-18 radials with the lowest usually 

 hooked. Flowers lemon yellow, 2 

 incrtes long, with 40-50 rounded 

 fringed sepals on the ovary, and about 

 25 fringed petals; the stigmata 12-15, 

 linear; the numerous black seeds at 

 maturity are enclosed dry and loose 

 in the fleshy scaly envelope, which is 

 pleasantly acid. E. Leopold} Hort. 

 Belg. is cited by Foerster, in his hand- 

 buch, ed. 2,473. as a synonym. (10-100) 

 ECHINOCACTUS DAMSII. 



Simple, depressed-globose, sparingly 

 tuberculate, ribs 10: spines 8, short, 

 straight, all radial: flowers numerous, 

 produced near the summit of the plant, 

 2%-2% inches long, white, green out- 

 side. Paraguay (MFK 1904, 119. f.). 

 IE. Emoryi. Major W. H. Emory, 

 United States commissioner on the 

 Mexican boundary survey, observed on 

 the 25th of October, 1846, this noble 

 plant, which Dr. Engelmann published 

 in 1848 in Emory's report. 156. figure 

 5. giving the following characters: 

 "18 inches in diameter; height equal 

 to the diameter; shape ventricose, 

 contracted toward the vertex, there- 

 fore somewhat urceolate; with 21 

 straight, sharp ribs; spines apparently 

 8, straight, brown, color of plant 

 bright green; vertex whitish (tomen- 

 tose?); fruit 1 or 1 % inches long, oval, 

 yellowish or reddish. Seed obovate, 

 obliquely truncated at base, full 1 line 

 long, black, opaque, slightly rough- 

 ened; embryo curved or hooked.
