Description edit
This species produces slender, reed-like stems, which bear distichously arranged, linear leaves. The inflorescence is erect and the rachis is bent apically.[2][3] The flowers have four laterally flattened pollinia.[4]The pollinia are relatively hard.[5]
Taxonomy edit
It was formerly placed in a separate, monotypic genus Neobenthamia Rolfe under the name Neobenthamia gracilis Rolfe. This is however now a synonym of Polystachya neobenthamia Schltr.[1] Under the inclusion of P. neobenthamia the genus Polystachya is a monophyletic group. This species is the sister group to Polystachya dendrobiiflora.[2]
