Colours: Flower white.
Habitat: Epiphyte in montane forest. Altitude 1600 m.
Flowering time in the wild: July.
Distribution: New Guinea (endemic).
Distribution in New Guinea: Papua New Guinea (Morobe and Southern Highlands Province).
Notes: We suspect that Kraenzlin's description of Dendrobium chordiforme is inaccurate, causing Schlechter to describe it once more as Dendrobium flagellum.
Cultivation: Intermediate growing epiphyte. Easily cultivated on a slab of tree fern.
