Common Name The Saber-Shaped Dendrobium
Flower Size .3" [.8 cm]
Found in the Assam, eastern Himalayas, Hainan China, south central China, Malaysia, Laos, Cambodia, Vietnam and the Moluccas in broadleaf evergreen lowland forests at altitudes of 500 to 2200 meters as a small to just medium sized, warm to cold growing epiphyte with tightly clustered, slightly zigzag, slender stems carrying 8 to 12, narrow, pointed, distichous, succulent, curved leaves that are folded which blooms on an axillary, at the upper nodes of a leafless pseudobulb, single flowered inflorescence occuring in the spring.
Repot immediately after flowering if needed. This species needs a definitive winter rest from water and fertilizer and should only be begun after initiation of new growth. Best mounted on tree fern or cork if given daily waterings through the summer months and high humidity the rest of the year
CAUTION Most likely all these photos are of D spatella. This species, occuring only in Ambon Island of Indonesia is very rare, I await photo confirmation!
