''Buddleja tubiflora'' is endemic to much of northern Argentina, southern Paraguay, and southern Brazil, where it grows at the edge of woodlands, thickets, and in old fields, at low elevations. The species was first named and described by George Bentham in 1846 〔Bentham, G. (1846). ''D C., Prodromus'' 10: 443, 1846.〕〔Norman, E. M. (2000). Buddlejaceae. ''Flora Neotropica 81''. New York Botanical Garden, USA〕 ==Description== ''B. tubiflora'' grows to < 2 m in height, with the typically lax habit creating a spread of < 3 m. The shrub is chiefly distinguished by its striking orange flowers, the corollas 25 mm long by 6 mm wide at the throat, borne in axillary clusters towards the ends of the branches. The branchlets, like the corolla tubes, are covered in a dense reddish indumentum. The leaves are mostly subsessile, lanceolate to ovate-lanceolate, 8 – 18 cm long by 2 – 6 cm wide, membranaceous, tomentulose above, tomentose below. Pollination is by hummingbirds which feed on the sweet nectar at the base of the corolla. Ploidy: ''2n'' = 38.〔
