Dendrobium amethystoglossum

A cane-type Dendrobium endemic to Luzon in the Philippines. It grows on mossy limestone cliffs at around 1,400 m and in winter produces pendent racemes of 15 to 20 fragrant white flowers with an amethyst-purple lip from its leafless canes. It needs intermediate temperatures, bright light, and a drier winter rest.
