''Hoya siamica'' is a slender vine found in Thailand with long light green leaves. The leaves are on average 1.5-2 cm wide by 4-10 cm long. It has white flowers that come in clusters of 10 to 15. The corolla of the flowers are white and flat; the corona can be a deep purple or a very pale yellow depending on how much light the plant receives. The flowers are approximately 1.5 cm in diameter, fuzzy, have a slight scent, and last about a week when they flower during the summer. ''Hoya siamica'' was first found by Arthur Francis George Kerr and published by W. G. Craib in 1911 in the Kew Bulletin. Kerr discovered the plant in the jungle on the mountain Doi Suthep which is near the city Chiang Mai, at an altitude of around 1500-1650 meters above sea level. The plant derives its name from Siam, the former name of Thailand. It was later also discovered in Gaoligongshan, Yunnan Province in China. ''Hoya siamica'' is related to ''Hoya longifolia''. == References == * Miscellaneous Information Bulletin of Kew (Kew Bulletin) p. 419 (1911) Classification H. siamica Craib Siamica Craib * Flora of China Vol. 16 p. 231 (1995) * Focke, Albers and Ulli Meve, Sukkulentenlexikon Volume 3, p.158 * Hoya telegraph 2 (2003) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Hoya siamica」の詳細全文を読む スポンサード リンク
