Buddleja speciosissima

Buddleja speciosissima is a shrub 1–3 m high with light-brown fissured bark. It bears hermaphroditic flowers, unlike most South American members of the genus which are cryptically dioecious.^[2] The young branches are thick, subquadrangular, and covered with a dense pale yellow indumentum, bearing subcoriaceous elliptic to lanceolate leaves with 1–3.5 cm petioles, and measuring 10–18 cm long by 2–4 cm wide, glabrescent above but tomentose below. The reddish-orange leafy inflorescences are 10–20 cm long, comprising 1–2 orders of branches bearing paired three flowered cymes, the corollas 25–30 mm long by 4 mm wide, pollination being by hummingbirds. Ploidy: 2n = 38.^[2]

The shrub is rare in cultivation.
