Common Name

Flower Size almost 1 1/4" [to 4 cm]

Found in Yunnan Province in the south of China at elevations of 200 to 1500 [1600 to 2150] meters as a medium to large sized, hot to cool growing epiphytic orchid with slender, occasionally branching stems carrying linear, 3/4" [2 cm] long or less, unequally bidentate apically leaves that blooms on a short, axillary, 1 to 2 flowered, fragrant inflorescence that arises from the apical leaf axils of last years mature canes and occuringin the spring with strongly scented [honey] flowers.

In the winter the water should be reduced and the fertilizer eliminated until new growth appears in the spring.

If your plant has leaves longer than 3/4" [2 cm] then your orchid is D hancockii. The column to D odiosum is much shorter and the ventral side of the column has a solid line of hairs going all the way across. In D hancockii the column is twice as long and the ventral side of the apex of the column has a few hairs in the center and sparsely anywhere else.
