Flowers very like those of S. densiflorum, but fewer and less dense. Pedicels slender, glabrous, stiff, reaching 1/2– 3/4 in. Calyx green, 1/16 in. long, with a very short tube and spreading lanceolate segments. Corolla whitish, 1/12 in. long, with a very short tube and reflexing oblong-lanceolate segments. Filaments subulate, as long as the corolla segments. Anthers minute, ovoid; staminodes linear-subulate, as long as the filaments. Ovary globose, densely pilose; style slender, 1/8 in. long, glabrous in the upper half.
