MATUCANA. 
103 
Type locality: Obrajillo, Peru, but not cited in the original place of publication. 
Distribution: Central Peru. 
Dr. Rose found this species fairly common among rocks just below Matucana, Peru. 
Its long, slender, scarlet flowers make it a very desirable plant for cultivation. This species 
was collected in abundance by Dr. Rose in 1914 but it has not yet flowered in cultivation, 
although it was flowering when collected. The original spelling of the specific name was 
haynii, named, according to Rumpler, for Friedrich Gottlieb Hayne, a professor of botany 
in Berlin, who was bom in 1832. Schumann in his Monograph wrote the name Echino- 
cactus haynei and we have adopted his spelling. 
In color, shape, and size, the flowers resemble 
those of species of Borzicactus (Cactaceae 2: 159); 
these, however, have the axils of scales on the 
corolla-tube hairy or woolly. 
Echinocactus heynei (Monatsschr. Kakteenk. 
20: 190. 1910) was never described. It may be 
simply a misspelling for E. haynei. 
We have referred here the illustration from the 
Garden because it is made from the same cut as the 
four other illustrations cited below. It is there 
described, however, as a foot high with white 
flowers!

DESCRIBED SPECIES. PERHAPS OF THIS GENUS. 
Echinocactus villosus (Monville) Labouret, Monogr. Cact. 239. 1S53. 
Cactus villosus Monville, Hort. Univ. i: 223. 1839. 
Echinocactus polyrhaphis Pfeiffer in Forster, Handb. Cact. 297. 1846. 
Echinocactus villosus crenatior Monville in Labouret, Monogr. Cact. 240. 1853. 
Simple, subglobose or short-columnar, somewhat depressed; ribs 13 to 15, somewhat tuber- 
culate, subcompressed, glaucous-green or somewhat violet or even blackish; radial spines 12 to 16, 
setaceous to subulate; central spines usually 4. 3 cm. long; flowers rose-colored without, white 
within; scales of the ovary and flower-tube naked in their axils. 
Type locality: Not cited. 
Distribution: Chile ( fide Schumann); Lima, Pern ( fide Labouret). 
This species is said to resemble Echinocactus acutissimus but is described by Schumann 
as having naked scales and the axils of the scales also naked. If it came from near Lima, 
Peru, as is usually stated, it is probably Echinocactus haynei. Sohrens claims it is from 
Huasco, Chile. 
Gymnocalycium villosum Pfeiffer is given by Forster (Handb. Cact. 297. 1846) as a 
synonym of E. polyrhaphis. E. polyrhaphis is written polygrhaphis by Labouret and poly- 
raphis by Salm-Dyck.
