Buddleja iresinoides is a species of flowering plant in the family Scrophulariaceae.[1][2] It is endemic to the rocky hillsides and stream banks of Bolivia and northern Argentina at altitudes from 300 to 1500 m.[3] The species was correctly identified as a Buddleja and named by Hosseus in 1924.[4]

Description

edit

Buddleja iresinoides is a dioecious shrub 1 – 3 m, occasionally < 5 m, high with light grey finely-striated bark. The pendulous branches are subquadrangular, tomentulose or tomentose, bearing lanceolate to ovate leaves 5 – 15 cm long by 2 – 5 cm wide on 0.5 – 1.5 cm petioles, glabrous above and tomentose, tomentulose, or even glabrescent below. The cream inflorescence is paniculate, 10 – 15 cm long with two orders of branches, the flowers borne in small globose heads 4 – 6 mm in diameter and comprising 3 – 12 flowers. The corolla is < 2 mm long and of differing shape depending on the sex of the plant, which led Fries to mistakenly identify two separate species (see Synonyms).[3]
