FragrancePart sunWarm TO CoolSpring

Common Name The Shoe-Lip Dendrobium [refers to the cavity at the base of the column foot] - In China Mei Gui Shi Hu - In Thailand Ueang Sai Nam Khieo

Flower Size 1 to 1.8" [2.5 to 4.6 cm]

Found from Hainan province of China, Assam, Bangladesh, eastern Himalayas, India, Nepal, Sikkim, western Himalayas, Myanmar, Thailand, Laos and Vietnam in semi-evergreen forests at elevations of 600 to 2100 meters as a small to medium sized, cool to warm growing epiphyte occuring on tree trunks as a suberect to pendant growing orchid that is best mounted on tree fern or cork. This species has tufted, suberect to pendulous, terete, striated, to 18" [to 45 cm] long, many noded stems each covered with a papery sheath, and carrying 5 to 9, oblong to narrowly lanceolate, acute leavesblooms in the spring on a short, purple inflorescence with the 1 to 4 shiny, waxy, delicately fragrant, longlasting flowers arising from near the apex of year old leafless stems. Drying out of the plant during the winter is nessasary with occasional waterings and no fertilizer until the initiation of new growth in the spring.

CAUTIONGoaverts at Kew, W3 Tropicos and IPNI all put D lawianum as a synonym of Dendrobium crepidatum, but it can easily be separated by the curving in one direction pseudobulbs, smaller white flowers .8" [2 cm] across, with an obscure mentum, and the differently shaped lip that is slightly clawed basally without a yellow patch and the column has 2 purple processes. So I have separated it and its synonyms, to see it please go to the listing for D lawianum
