Common Name or Meaning The Compressed Mentum Dendrobium
Flower Size 1.4 [3.5 cm] long
Found in Sumatra in montane forests at elevations of 1400 to 1800 meters as a small to medium sized, cool growing epiphyte with close set, unbranched, slightly zig-zag at the narrower apex canes carrying many, lanceolate to ovate-lanceolate, somewhat basally twisted, apically gradually narrowed to acuminate leaves that blooms in the late winter and mid summer on a very short, towards the apex, single flowered inflorescence with pale yellow to greenish yellow flowers that somethimes have red streaks on the column.
Allied to D sanguinolentum.htm but with a much longer metnum and claw of the lip, the lip with a much shorter appendage on the claw and a distinct callus on the blade and a very different anther. Somewhat similar to D pedicellatum but it has the lip adnate to the column foot at the base without a callus on the blade, the column is much longer and the color is completely different.
CAUTION I have no way of verifying this determination so please use with caution. The Drawing is much more likely to be correct as it is based of J J Smith's original determination
