Buddleja X wardii C. Marquand has been named for what is probably a hybrid between B alternifolia and B. crispa (C. Marquand, J. Linn. Soc., Bot. 48: 203. 1929). This hybrid species has been collected in SE Xizang and has the following characteristics: Shrubs 1--5 m tall. Branchlets stellate tomentose, glabrescent. Leaves opposite or alternate; leaf blade elliptic to subelliptic, 0.5--5 X 0.3--2 cm, shortly stellate tomentose, margin repand-crenate, apex acuminate to acute. Inflorescences cymose, 1.5--2 cm in diam. Calyx campanulate, tube ca. 2 mm; lobes triangular, 0.5--0.7 mm, outside densely stellate tomentose. Corolla lilac, with an orange throat, tube 6--7 X 1--1.5 mm. Stamens inserted at middle of corolla tube, included. Ovary subglobose, ca. 1 mm in diam., stellate tomentose. Style longer than ovary. Capsules subellipsoid, ca. 5 mm in diam., stellate tomentose.
