Simple or clustered, subglobose, about 12 cm. in diameter; ribs about 12, prominent, slightly 
undulate; areoles circular, filled with white wool; spines subulate, black, 10 to 12 mm. long; flowers 
from the side of the plant, 15 to 20 cm. long; inner perianth-segments spreading, white, acuminate; 
filaments and style projecting a little beyond the throat; axils of scales on flower-tube bearing long 
wool. 
Type locality: Not cited. 
Distribution: Provinces of Tucuman, Catamarca, and Salta, Argentina; recorded from 
Brazil. 
Pfeiffer (Enum: Cact. 71. 1837) gives Echinocactus tubiflorus as a synonym of Cereus 
tubiflorus. _ 
Salm-Dyck (Cact. Hort. Dyck. 1849. 39. 1850) gives Echinopsts zuccariniana Pfeiffer 
instead of E. zuccarinii and Riimpler uses this spelling. Under £. zuccarimtana several 
floral and abnormal forms have been described as varieties, among which are rosea, cristata, 
monstrosa, picta, rohlandii, and nigrispina and under E. zuccarinit, monstruosa, nigrispina, 
and picta; some of the same varieties appear under E. tubiflora including nigrispina, 
rosea, and rohlandii. Walpers (Repert. Bot. 2: 324. 1843) credits the name Echinonyc- 
tanthus nigrispinus to Lemaire, but Lemaire used the name nigrispinus only as a variety 
of E. tubiflorus.
