100 THE CACTACEAE. 
Type locality: Chile. 
Distribution: Mountain ridges in Chile. 
In both the illustrations cited below the scales on the ovary and flower-tube are ovate 
and overlapping and are not shown as woolly or setose in their angles. Schumann, how- 
ever, describes them as such and, if so, the species must be of this relationship. 
Here we would refer the two varieties, brevispinosus Forster (Allg. Gartenz. 15: 51. 
1847) and rigidior Salm-Dyck (Cact. Hort. Dyck. 1849. 33. 1850). 
Echinocactus neumannianus Labouret (Monogr. Cact. 245. 1853) is referred by Schu- 
mann as a synonym of this species. It comes from Copiapo, Chile, and may be a differ- 
ent species. 
Echinocactus neumannianus rigidior (Salm-Dyck, Cact. Hort. Dyck. 1844. 18. 1845) 
is only a name. 
Schumann also refers here Echinocactus supertextus Pfeiffer (Abbild. Beschr. Cact. 2: 
under pl. 14. 1847), but the description reads more like that of E. curvispinus. This is 
the conclusion reached by Mr. Sohrens of Santiago. Specimens so named in the Philippi 
Herbarium we would certainly refer to Neoporteria. 
The species was named for Dr. Gustave Kunze, at one time director of the Botanical 
Garden at Leipzig.

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; spines straight, acicular, black; radial spines 5 or 6, suberect; central 
spine solitary; flowers and fruit unknown. 
Type locality: Not cited. 
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 
Echinocactus horizonthalonius as it was by Schumann.

ECHINOCACTUS PEPINIANUS Schumann, Gesamtb. Kakteen 420. 1898. 
This species is very different from the species so named by Lemaire. Its flowers and fruit are 
unknown and its relationship is not known tous. If it is from Chile or Peru, as Schumann suggests, 
it may be referable to one of the species of C opiapoa. Fornoteon Echinocactus pepinianus Lemaire, 
see Britton and Rose (Cactaceae 2: 137. 1920). 
ECHINOCACTUS SUBNIGER Poselger in Forster, Handb. Cact. ed. 2. 588. 1885. 
_ Simple, globose to short-columnar; ribs 16, grayish green; radial spines 8, 1.5 cm. long; central 
spines 1 to 3, 2 cm. long. 
Type locality: Mexico. 
This species is recognized by Schumann, but its flowers and fruit are unknown. It is 
impossible, without seeing a specimen, to make out its generic relationship. If it came from 
Mexico, as Rimpler thought, it does not belong to Neoporteria, but if it is from Chile, as 
Schumann believed, it should probably be placed there.

Either simple or cespitose, globular to short-cylindric, small cacti; ribs numerous, low, somewhat

scales long-hairy but not spiny nor bristly; fruit so far as k isci )

Type species: Echinocactus leucotrichus Philippi. 
The genus as here treated consists of two species, one of which has heretofore appeared 
under several specific names, sometimes in Echinocactus and sometimes in Echinopsts, 
although it has little in common with either genus and, especially, as these genera are now
