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 Riimpler, for Friedrich Gottlieb Hayne, a professor of botany 

 in Berlin, who was born 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. 1 9 10) 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 polyrliaphis 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- 

 eulate, 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, Peru {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. polyrliaphis. E. polyrliaphis is written polygrhaphis by Labouret and poly- 

 raphis by Salm-Dyck.
