|genus = Buddleja |species = longiflora |authority = Brade }}Buddleja longiflora is a rare species endemic to one small area of Brazil, growing in fields high on the Serra do Caparaó at an altitude of 2400 m.[1] The species was first described and named by Brade in 1957.[2] DescriptionBuddleja longiflora is a shrub 0.5 – 1 m high. The young branches are densely tomentose, bearing lanceolate leaves 10 – 17 cm long by 1.2 – 2.7 cm wide, glabrescent above, tomentose below, with petioles 1 – 2.5 cm long. The yellowish orange inflorescence is < 15 cm long, the flowers borne in paired 3 – 5 flowered cymes. The eponymous long flowers have corollas 35 – 42 mm long by 4 – 5 mm wide.[1]The species could be mistaken for B. speciosissima found in nearby Itatiaia, but for minor differences in flower and leaf dimensions. It is possible B. longiflora could be classified as a subspecies of the latter should more material be availed for examination.[1] CultivationThe species is not known to be in cultivation.
