Common Name The Toba Dendrobium [A lake and town in Sumatra]

Flower Size 3" [7.5 cm]

Found in Sumatra in pine and montane forests at elevations of 750 to 1500 meters as a small sized, warm to cool growing orchid with cylindrical stems carrying 8 to 9, oblong-ellptic, smooth on top, hairy beneath leaves that are apically bilobed and have leaf sheaths covered in black hairs, blooming on a very short, successively single, several flowered inflorescence that arises from the base of the leaf sheath opposite the leaf occuring in the fall.

A slight lessening of water and fertilizer should occur through the winter months and should be resumed only with the initiation of new growth in the spring.

Very similar to D ayubii but differs in that this one has a very narrow lip apex that widens slightly in the apical half.
