Found in Papua New Guinea in montane forests at elevations around 800 meters as a medium to just large sized, warm growing terrestrial or epiphyte with erect to suberect, narrowly lanceolate, acuminate, glabrous, plicate, gradually narrowing below into the petiolate base leaves that blooms in the spring and again in the late summer and early fall on an erect, terete, glabrous, rachis 2.4 to 3.6" 6 to 9 cm] long, overall 24 to 32" [60 to 80 cm] long, cylindrical in form, many flowered inflorescence with sheaths around the base and erect, spreading, narrowly lanceolate, acuminate, deciduous floral bracts.

Many authors put this entity as a synonym of C ventilabrum but the cited differences between this and C ventilabrum is that C chrysantha has long parallel rugose calli on the lip, unfortunately that cannot be seen on the photo provided.

CAUTION I have no way of verifying this determination [The photo does not have enough lip detail] so please use with caution.
