Description

Buddleja thyrsoides is a dioecious shrub 1 – 3. m tall, with tan bark, the young branches covered with white tomentum. The leaves are sessile or subsessile, linear or linear-lanceolate, the blade 7 – 15 cm long by 0.4 – 3 cm wide, subcoriaceous, glabrescent above, and white tomentose below. The fragrant white leafy inflorescences are 5 – 15 cm long by 2 – 3 cm wide, comprising 1 – 2 orders of branches, 0.5 – 2 cm long with cymose clusters of 5 – 15 flowers; the tubular corollas 3 – 4 mm long.[1]

Subspecies

Norman identifies two subspecies distinguished by narrower seeds and denser tomentum resp.:[1]

  • Buddleja thyrsoides subsp. angusticarpa
  • Buddleja thyrsoides subsp. thyrsoides (synonyms= Buddleja chloroleuca Kraenzl., Buddleja salicifolia Vahl.)

Cultivation

Neither the species nor its subspecies are known to be in cultivation.

gollark: No, I can draw *slightly* mentally and offload more complicated stuff to paper.
gollark: Not really.
gollark: Did you not know of this? It's quite common. Some people don't have internal monologues either.
gollark: (it is called aphantasia)
gollark: So, I can't actually mentally visualize anything more complicated than assemblages of lines.
