Part Sun Warm Fall

Common Name or Meaning Summerhayes' Dendrobium [English Orchid Botanist and African Specialist 1900's]

Flower Size .8" [2 cm]

Found in New Guinea on trees in forests at elevations of 600 to 700 meters as a medium sized, warm growing epiphyte with an unbranched, erect to arching, elongate, flexuous, slender, glabrous stem carrying all along the stem, patent to erect-patent, elliptic, unequally bilobed apically, glabrous leaves that blooms in the fall on very short, subsessile, 2 flowered inflorescence

I am not sure of this determination, I have checked Schlechter's drawing of D pictum which is designated as a synonym of D summerhayesianum and it does not compare well for the overall view of the positioning of the sepals and petals. I have no other relevant references.
