ECHINOCACTUS. 177 
Cactus depressus Haworth (Syn. Pl. Succ. 173. 1812). Haworth’s plant, however, was 
described as having 10 ribs and was believed to be related to Cactus gibbosus, that is to 
Malacocarpus. 
ECHINOCACTUS ECHINATUS Forbes, Journ. Hort. Tour Germ. 152. 1837. 
Like a hedgehog cactus; ribs 19; spines light brown, elongated. 
This species is so briefly described that it can not be definitely identified. It is perhaps 
a Ferocactus. It is said to have come from Mexico. 
ECHINOCACTUS GEISSEI Poselger in Schumann, Gesamtb. Kakteen 406. 1898. 
Echinocactus geissei albicans Hildmann in Schumann, Gesamtb. Kakteen 406. 1898. 
Neither has this species nor its variety been known to flower and as we have not seen 
the plants we are not able to suggest their relationship. The only illustration which we 
have seen (MOllers Deutsche Gart. Zeit. 25: 474. f. 6, No. 14) indicates that it is not a true 
Echinocactus. It is recorded as from Chile or Bolivia. 
ECHINOCACTUS HAMATUS Forbes, Journ. Hort. Tour Germ. 152. 1837. 
Undoubtedly different from Mithlenpfordt’s species of the same name. It presumably 
had hooked spines judging from the name; and was briefly described as having a depressed 
stem, 21 ribs, and 7 gray spines. Forbes reports it was introduced from Buenos Aires in 
1833. It does not answer to any Argentine plant we know. 
ECHINOCACTUS MALLETIANUS Lemaire, Allg. Gartenz. 13: 387. 1845. 
Stems 'simple, depressed-globose or somewhat cylindric, very woolly at the top, 1 dm. high; 
ribs 15 to 17, more or less repand; spines straight, acicular, black; radial spines 5 or 6, suberect, 
central spine solitary; flowers and fruit unknown. 
Type locality: Not cited. aor 
Distribution: According to Schumann, Chile or Bolivia. _ 
Dr. Rose obtained from L. Quehl a photograph of this species as it is now represented 
in collections. Its relationship is doubtful but it should certainly not be placed just after 
E. horizonthalonius as it was by Schumann. 
ECHINOCACTUS MUTABILIS Forster, Hamb. Gartenz. 17: 161. 1861. . . oo 
Simple, globose; ribs 10, sinuate and tuberculate, yellowish green to violet ; radial spines 7 or 8, 
spreading, straight or somewhat curved, dull yellow; central spine solitary, straight, porrect. 
Type locality: Peru. ; . 
Distribution: Reported from Peru, but since this species was discovered the southern 
provinces have been annexed by Chile. It is not of this genus.

We do not know this species. It seems to have been well known 1n Europe at one time

Mr. Sdhrens of Chile tells us he has seen it near Huasco, Chile. bahrenie iba uncer 
as to its generic relationship. It may be a near relative of Lobivia cumingi.
