Buddleja soratae is a rare species endemic to one small area of Bolivia around Sorata, growing along forest edges at altitudes of 2,700 – 3,200 m; it was first described and named by Kraenzlin in 1913.[1] [2]
Buddleja soratae is a dioecious shrub or small tree 5 - 6 m high. The younger branches are quadrangular, the youngest sections tomentose, bearing membranaceous lanceolate to elliptic leaves with 0.5 - 1 cm petioles, and are 7 - 14 cm long by 2 - 4 cm wide, glabrescent above but tomentose below. The orange leafy-bracted inflorescences are 12 - 15 cm long by 10 - 15 cm wide, comprising 2 - 3 orders of branches bearing cymes of 6 - 9 flowers on peduncles 0.5 - 1 cm long.[2]
Buddleja soratae is considered very similar to B. cardanasii and B. multiceps, differing from the latter only in the shape of the leaves.[2]
The shrub is not known to be in cultivation.
