Part Shade cool Spring

Common Name or Meaning The Folded Lip Dendrobium

Flower Size .4" [1 cm]

Found in Sumatra at elevations of 1500 to 1700 meters as a cool growing epiphyte with a branching stem and carrying in the upper 2/3's, distichous, ovate, twisted to be in one plane, unequally apically bilobed, basally clasping leaves that blooms in the spring on axillary, single flowered inflorescence arising on leafy canes.

Similar to D connatum but this one differs in the colors [initially greenish-white with green veins, but soon changes to yellow green to light brown or salmon with darker green to brown veins] of the flower, the broader petals, the large flap like side lobes to the lip and 2 large, very swollen papillose keels that extend from the hypochile to the middle of the epichile.
