Corolla lilac, 5--8 mm; tube 4--6.5 X 1.5--3 mm, outside glabrous or pilose above middle; lobes suborbicular, 1.2--1.5 X 1.2--1.5 mm. Stamens inserted just inside corolla mouth; anther sessile. Pistil glabrous. Ovary ovoid, 1.5--1.7 mm. Style 1--1.5 mm; stigma clavate. Capsules ellipsoid, 5--8 X 2--3 mm, glabrous. Seeds brown, spindle-shaped, with slender wings at ends. Fl. Feb-Sep.

Buddleja X alata Rehder & E. H. Wilson has been named for what is probably a hybrid between B. albiflora and B. nivea (Rehder & E. H. Wilson in Sargent, Pl. Wilson. 1: 570. 1913). This hybrid species has been collected in W Sichuan at 1300--3000 m and has the following characteristics: Shrubs 1--3 m tall; young branchlets, petioles, leaves abaxially, calyces, and corollas with scattered stellate and glandular hairs to almost glabrous. Branchlets 4-angled and with 4 elevated wings. Petiole 1--1.5 cm; leaf blade narrowly ovate, 15--25 X 4--8 cm, base cuneate, margin serrate, apex acuminate, veins reticulate. Inflorescences terminal and in axils of apical leaves, seemingly racemose or thyrsoid cymes, 10--20 X 1.5--2.5 cm; bracts and bracteoles awl-shaped, ca. 2.5 mm. Calyx campanulate, ca. 3 mm; lobes triangular, ca. 1 mm. Corolla lilac, outside stellate tomentose; tube ca. 5 mm, inside pilose but glabrous at base; lobes suborbicular, 1--1.5 X 1--1.5 mm, inside pilose only at base. Stamens inserted just below corolla mouth. Ovary ca. 1 mm, stellate tomentose. Style ca. 1 mm; stigma clavate, ca. 0.5 mm. Capsules oblong, ca. 5 mm, sparsely stellate tomentose. Seeds winged at both ends. Fl. Apr-Oct.
