Description
Dendrobium glabrum is an epiphytic herb that has shiny, yellowish green pseudobulbs 40–50 mm (1.6–2.0 in) long and 12–15 mm (0.47–0.59 in) wide. There is a single leathery leaf 60–75 mm (2.4–3.0 in) long and 10–15 mm (0.4–0.6 in) wide with a papery bract at its base. Short-lived, star-shaped white flowers with yellowish tips 20–25 mm (0.79–0.98 in) long and wide are produced in leaf axils on a thin stalk about 30 mm (1.2 in) long. The sepals are 14–16 mm (0.55–0.63 in) long and about 2 mm (0.08 in) wide, the petals slightly longer but only half as wide. The labellum is about 8 mm (0.3 in) long and 3 mm (0.1 in) wide with wavy edges near its base and two ridges along its midline. Flowering occurs sporadically and the flowers only last a few hours.[2][3][4]
