Growths forming small clumps, or sometimes growing singly, and as imported 8-14 lines long, 3 1/2-8 lines broad and 2-5 lines thick, compressed cylindric or oblong in side view, shortly 2-lobed and somewhat truncate at the top; lobes 1 1/2-3 1/2 lines long, pressed together, convexly truncate at the top, their upper part very distinctly window-like and semi-transparent in side view when held against the light; substance soft and pulpy; surface smooth, and when viewed with a strong lens against the light seen to be covered with microscopic points, scarcely pubescent and scarcely velvety to the touch, green, with the upper part of the sides often tinted with brown, and the window part of the lobes pallid. Flowers seen only in a withered condition. Calyx usually 6 (sometimes 5)-lobed, green; tube 3-4 lines long; lobes 2 lines long, 4 of them with white membranous margins. Corolla apparently about an inch in diameter; tube 4.5 lines long; petals in 1-2 series, 5-5 1/2 lines long, 1/3-1/2 line broad, cuneately linear, obtuse or slightly notched at the apex, with a few-inner ones that are shorter and filiform-linear (perhaps staminodes). Stamens numerous, in 3-4 series in the throat of the corolla-tube, all exserted and the longer exserted about 1 line from the tube; filaments and anthers yellow. Style 3 1/2-4 1/2 lines long and nearly or quite as long as the corolla-tube, filiform; stigmas 5-6, filiform, 3/4-1 line long. Capsule 1 3/4-2 lines in diameter when closed, pallid, slightly convex on the top, with 5-6 valves having their tips raised into a short, conical point at the centre; valves almost transparent when expanded, pallid; expanding-keels contiguous into a stout central keel, ochreous, with very broad membranous marginal wings; cells without cell-wings or placental tubercles. Seeds 1/3 line long, subglobose, without a point, smooth, light brown.
