ECHINOPSIS. 
6 7 
Echinopsis decaisneana is a delicately fragrant, beautiful pink form with large flowers; 
the inner perianth-segments are oblong, acute or acuminate. It is a hybrid between this 
and some other species. The flowers open during the day and last usually for more than 
one day.

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-Dyek (Cact. Hort. Dyck. 1849. 39. 1850) gives Echinopsis zuccariniana Pfeiffer 
instead of E. zuccarinii and Riimpler uses this spelling. Under E. zuccariniana several 
floral and abnormal forms have been described as varieties, among which are rosea, cristata, 
monstrosa, picta, rohlandii, and nigrispina and under E. zuccarinii, 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. 
Echinopsis droegeana Berger (Monatsschr. Kakteenk. 1: 24. 1891) is probably a hybrid 
with this species as one of the parents. 
Echinopsis zuccarinii robusta is in the trade (Grassner).
