H. Allen), glabrous within, si>arscly hairy without except near the tips of the lobes, where the hairs and enlarged hairlike processes are densely aggregated and form a conspicuous fringe, the tube 36-43 mm. long, practically straight, slightly contracted above the base and then gradually enlarged to the mouth (maximum width, when pressed flat, about 10 mm.), the lobes linear or nearly so, acute, not at all or but slightly curved, the two upper lobes 2-2.5 mm. wide, 20-30 mm. long, the three lower lobes similar, slightly shorter; filament-tube 50-56 mm. long, longer than the corolla-tube but scarcely appearing exserted because of the semi-erect corolla-lobes, glabrous, the filaments distinct at base and fused to the corolla-tube; anther-tube 8-1 1 mm. long, bluish-gray, the anthers glabrous, the two shorter anthers prominently white-tufted at tip, the hairs 2 mm. long or less; hypanthium in anthesis turbinate, obtuse at base, thence widened for about four-fifths of its length and then somewhat contracted to the base of the lobes, its outer surface sparsely hairy, the hairs like those of the leaves; fruit "bladdery" (according to H. E. Stork), not seen; calyx-lobes linear or linearsubulate, acute, obscurely or plainly toothed, hairy on the backs and margins, 1.5-3 mm. wide at base, 10-18 mm. long, fused at base, forming a rim 1-3 mm. wide above the free part of the ovary; seeds about as in C. solanif alius.
