Ovary 9–12 lines long, whole flower 6–8 inches long, about 2½ inches in diameter; bristles at base of tube 1–2 lines, or upwards 4–6 lines, and in var. β. 6–10 lines long; style not reaching above the large anthers; stigmata about 10, suberect. Berry ovate, 1¼–1½ inch long, an inch in diameter, slightly contracted at base, but not stiped nor even clavate, as I formerly was induced to believe, somewhat rostrate at the upper end, bright scarlet, fleshy, and edible.

Areolæ about one line long, also about one line apart; spines whitish or ashy, and in some specimens with light brown tips; sometimes I find only 14–16 radial spines, (1 upper, 1 lower, and 6–7 pairs of lateral ones); the older and larger ones have 7–9 pairs of lateral spines, 1 lower one, and often 3–5 small bristly upper spines. Upper spines ½–1 line, lower one 1–2 lines, and the others 3–4 lines long. Central spines in a single longitudinal series one above the other, 1–3 lines long. Flower bright yellow, with a light green centre and dark green stigmata, open from 8 or 9 till one o’clock, 2½–3¼ inches long, 2½–3½ inches in diameter, the broad and obtuse petals forming an even uninterrupted margin all around.

Flower 2½ inches long, of the same diameter; petals fewer and narrower than in the last species, only 6 lines wide, paler, (rose-colored,) and mostly quite obtuse and almost entire. Ovary in this, as in the last species, remarkably small and undeveloped, while the flower is fully open; its spines few and short, growing afterwards in length and numbers more than is noticed in any other species. Ripe fruit 1–1½ inch long, with 20–24 pulvilli, on each of them 9–12 bristly spines, 4–9 lines long; fruit green or rarely purplish, insipid or pleasantly acid.
