Buddleja vexans : ウィキペディア英語版 | Buddleja vexans ''Buddleja vexans'' is a newly (2000) recognized species endemic to central Peru, growing along streams, roads and cliffs at altitudes of 3,300 – 3,900 m. Norman adjudged the plant to be a probable hybrid between ''B. coriacea'' and ''B. incana''.〔Norman, E. M. (2000). Buddlejaceae. ''Flora Neotropica 81''. New York Botanical Garden, USA〕 ==Description== ''B. vexans'' is a sterile shrub 3 – 5 m high with a trunk < 30 cm in diameter, the bark brown and fissured. The younger branches are terete and tomentose, bearing coriaceous elliptic leaves 4.5 – 8 cm long by 1 – 3 cm wide, glabrous and rugose above, densely tomentose below. The fragrant golden-orange paniculate leafy-bracted inflorescences are 5 – 12 cm long by 5 – 9 cm wide, comprising 1 – 2 orders of branches bearing heads 1.5 – 2 cm in diameter, each with 16 – 20 flowers, the corollas 4 – 5 mm long.〔 A popular garden plant in Peru, Norman considers ''B. vexans'' to have the greatest horticultural merit of all the American buddlejas.〔
