Buddleja araucana : ウィキペディア英語版 | Buddleja araucana ''Buddleja araucana'' is endemic to the semi-deserts and steppes of Patagonia, from southern Mendoza to Río Negro and Neuquen provinces in Argentina, and adjacent Chile.〔Norman, E. M. (2000). Buddlejaceae. ''Flora Neotropica 81''. New York Botanical Garden, USA〕 The species was first described and named by Philippi in 1873,〔Philippi, R. A. (1873). ''Anales Univ. Chile'' 525-526, 1873;〕 it was introduced to cultivation by the British gardener and plant collector Harold Comber() as a form ''B. globosa'' in 1925. 〔Bean, W. J. (1914). ''Trees and shrubs hardy in the British Isles''. Eighth edition, revised by D. L. Clarke, 1989. Vol. 1, A-C. Murray, London.〕 ==Description==
''B. araucana'' is a dioecious shrub, 1–3 m tall, with grey fissured bark. The young branches are terete and tomentose, bearing sessile coriaceous leaves linear to lanceolate tomentose on both sides, 3–9 cm long by 0.8–1.8 cm wide. The light orange inflorescence comprises one terminal globose head and 1–5 pairs of pedunculate heads in the axils of the progressively larger leaves; the heads are 1–2 cm in diameter and contain 25–45 flowers, the corolla is tomentulose, 4–5 mm long, with warty hairs inside. Ploidy: ''2n'' = 38.〔 The species is easily confused with ''B. globosa'', but the latter has larger, more glabrous leaves, and larger flowerheads comprising more flowers.
