Common Name The Broad-Bellied Dendrobium

Flower Size 3/4 to 1 1/4" [1.5 to 3 cm]

A New Guinea, New Caledonia, Solomon Island and Vanuatu minature sized, hot to cool growing, epiphytic species found at elevations of 0 to 1200 meters with moss and ferns in dense lowland and montane, humid forests near watercourses, mangrove swamps, moss forests and plantations with erect, clustered, flattened and club-shaped towards the apex, basally narrow stems enveloped by leaf sheaths carrying 2 to 8, oval, thin, medium green, deciduous leaves after flowering that occurs in the spring and again in the fall on a terminal or lateral, short to 1 1/4 to 2 3/8" [3 to 6 cm] long, erect, few flowered, racemose inflorescence that arises from the nodes near the apex of leafed and leafless canes with non-resupinate flowers

This species and D platycaulon are both cited as synonyms one way or the other, but I have left them separate at this time. Please refer to the other species for more information. I feel that P platycaulon is confined to the Philippines and has three raised keels in the throat of the lip, D platygastrium has several and is found in New Guinea, New Caledonia, Solomon Islands and Vanuatu.
