Description.
"Saccolabiopsis rectifolia" is a large epiphytic or lithophytic herb that forms large, straggly clumps and has thick, cord-like roots and thick, branched stems long. There are many fleshy, strap-like leaves long and wide at intervals about apart. A large number of resupinate cream-coloured, yellowish or greenish flowers with purple or brown spots, long and wide are arranged on a branched flowering stem long with between five and fifteen flowers on each branch. The sepals are long and wide, the petals a similar width but slightly shorter. The labellum is white with rose-coloured spots, about long and wide three lobes. The side lobes are triangular and the middle lobe is fleshy with a spur and a large, fleshy callus. Flowering occurs from April to August.
Taxonomy and naming.
The goliath orchid was first formally described in 1891 by Robert Allen Rolfe who gave it the name "Stauropsis warocqueana" and published the description in "Lindenia: iconography of orchids". In 1972, Leslie Andrew Garay changed the name to "Sarcanthopsis warocqueana". The specific epithet ("warocqueana") honours "M. G. Warocqué", in whose garden it flowered, producing the type specimen.
Distribution and habitat.
"Sarcanthopsis warocqueana" grows from rocks on the coast, just above the water line to the branches of trees in rainforest at above sea level. It is found in eastern New Guinea and nearby islands. A single juvenile plant has been observed on Moa Island, Queensland.
