Dendrobium gratiosissimum

A deciduous Dendrobium with pendulous, swollen-noded canes that flower from the leafless nodes in spring, bearing one to three fragrant pale pink flowers per node. It grows as an epiphyte from Assam and Yunnan to Hainan and Indochina at about 500–1,700 m, in forests with a wet summer and a cool, dry winter. In cultivation it needs a warm, wet growing season and a distinct cool, dry winter rest to flower.

Where it grows wild

An epiphyte in evergreen, semi-deciduous and deciduous forest, dry lowland forest, savanna-like woodland and primary montane forest. In Vietnam it has been collected in evergreen broadleaved forest beside mountain streams. The pendulous canes are yellow with purple stripes and drop their leaves before flowering.

IOSPE gives 500–1,700 m. GBIF records with elevations centre on about 1,250 m; the 5,000 m maximum is an error.
