Found in New Guinea in lower montane forests at eleavtions around 1500 meters as a large sized, cool growing terrestrial with an erect stem enveloped in the basal half by tubular shaeaths and leafy above stem carrying about 10, distant, sessile, lanceolate, acuminate narrrowing below into the base leaves that blooms in the spring on an erect, terminal, peduncel provided with a few foliaceous scales towards the apex, to 10" [25 cm] long, many flwoered inflorescence with ovate-oblong, gradually long caudate-acuminate longer than the ovary floral bracts and carrying green flowers.
"Habenaria pinnatipartita can be distinguished from H. paucipartita based on the petal and lip shape. In the latter the anterior petal lobe is almost entire (vs with a single filiform segment), lip lateral lobes have a few subulate projections and short, irregular teeth (vs lateral lobes with 2 to 3 patent, unequal, filiform lobules and sometimes near the apex). The unique character of this species is the presence of a longitudinal rib on the dorsal side of the spur, not found elsewhere, In the field both species can be recognized also by the flower color—in H. pinnatipartita it is uniformly green, whereas in H. paucipartita – the lip is white, and the other flower segments are green."
