Common Name The Long-Stemmed Arachnis

Flower Size 2" [5 cm]

Found in the New Guinea as well as the Philippines in lowland forests at elevations around 150 to 1000 meters as a giant sized, hot to warm growing epiphyte with a monopodial, erect, rigid, terete, elongated, apically flattened stem covered by tubular sheaths and carrying leathery, strap-shaped, oblong leaves that are unequally bilobed apically and blooms in the winter and fall on an axillary, opposite the leaves, short to 4" [10 cm] long, loosely to 4 flowered inflorescence with fleshy, fragrant flowers

This species is very similar to if not the same as A celebica from the Sulawesi if so then that name takes precedence.
