Dendrobium convexum, commonly known as the piggyback orchid, [2] is an epiphytic orchid in the family Orchidaceae. It has a creeping, brittle root, erect pseudobulbs with a single leaf on the top and one or two cream-coloured, short-lived flowers with a red and yellow labellum. It is native to Southeast Asia, New Guinea and tropical North Queensland, Australia.
Dendrobium convexum is an epiphytic herb with a brittle root about 3 mm (0.1 in) thick creeping over the surface of rough-barked trees. Shiny pseudobulbs 40–50 mm (1.6–2.0 in) long and 8–10 mm (0.31–0.39 in) wide arise at well-spaced intervals along the root, each on a thin stalk about 10 mm (0.4 in) long. There is a single dark green leaf 50–80 mm (2–3 in) long and 15–18 mm (0.59–0.71 in) wide on the end of the pseudobulb. One or two cream-coloured flowers 12–15 mm (0.47–0.59 in) wide appear at the base of the leaf on a pedicel 5 mm (0.2 in) long. The dorsal sepal is 5–7 mm (0.20–0.28 in) long and about 4 mm (0.16 in) wide. The lateral sepals are 3–4 mm (0.12–0.16 in) long and the petals are linear, 5–6 mm (0.20–0.24 in) long and about 1 mm (0.04 in) wide. The labellum is yellow with a red centre, about 11 mm (0.43 in) long and 4 mm (0.2 in) wide and has three lobes. Flowering occurs sporadically and the flowers open for less than a day.

The piggyback orchid was first formally described in 1825 by Carl Ludwig Blume who gave it the name Desmotrichum convexum. [6] He published the description in his book Bijdragen tot de flora van Nederlandsch Indië. [6] [7] In 1831, John Lindley changed the name to Dendrobium convexum. [8] The specific epithet (convexum) is a Latin word meaning "arched outward" or "protuberant". [9]
Dendrobium convexum grows in mangroves, humid areas of scrub, forest and rainforest mainly on rough-barked trees. It occurs in Malaysia, Thailand, Indonesia, New Guinea and on the Cape York Peninsula as far south as Innisfail, Australia. [2] [3] [4]
