Commentaires

Publication originale:
"79. Opuntia pascoensis sp. nov.
Stems erect and rigid, up to 3 dm. high; joints easily breaking apart, erect or ascending, terete or slightly flattened, 3 to 12 cm. long, 1.5 to 4 cm. broad, puberulent, hardly tuberculate but with faint upturned lunate depressions between the dark-blotched areoles; leaves minute; areoles somewhat elevated, filled with brown wool intermixed with longer white cobwebby hairs; spines 4 to 8 on young joints, more on older joints, acicular, yellow, 2 cm. long or less; glochids numerous, short, yellow, tardily developing; fruit globular, 1.5 cm. in diameter, naked below, spiny above. Doubtless of wide distribution, for the joints are easily detached and are distributed like burs, but so far only two collections have been reported.
Collected by Dr. and Mrs. J. N. Rose in central and southern Peru, in 1914, first from just below Matucana (No. 18653), and later at Pasco (No. 18812, type).
Plate XVII, figure 1, represents a joint of the type specimen above cited."

Type: Dr. et Mrs. J. N. Rose 18812, Pérou, province de Pasco, ville de Pasco, 1914, conservé au New York Botanical Garden (NY: holotype et isotype).
