Phalaenopsis robinsonii is a species of orchid native to Maluku, Indonesia.[1] The specific epithet robinsonii refers to the botanist and collector of the type specimen Charles Budd Robinson (1871-1913).[2]
It is a pendulous epiphyte with 4–5, up to 31 cm long and 5.7 cm wide leaves. Fleshy, white flowers with lilac spots are produced on few-flowered, arching, branched or unbranched inflorescences. The lateral lobes of the labellum are unusually small.
This species is placed in the section Amboinenses of subgenus Polychilos.[3] An affinity to Phalaenopsis amboinensis or Phalaenopsis modesta has been reported.
