Finding
SITF has determined this plant to be Bulbophyllum alticola, not Bulbophyllum longilabre (Mar 2025). Based on flower morphology and the form of the pseudobulbs, this plant is a match for B. alticola. These pseudobulbs are more conical than is B. longilabre and the lip has only two discernible keels, rather than three. The photos of B. alticola in the POWO and IOSPE are a close match to this plant.

Aw. description: Two flowers and 13 buds on 15 inflorescences grown on an 8-cm wide by 14-cm long tree fern slab; flowers cream;sepals striped deep burgundy; minute petals deep burgundy, porrect; lip cream, cylindrical, enlongated; column cream, anther cap deep burgundy; substance firm; texture matte.Other details: The plant was submitted to the judging center as Bulb. longilabre, however the botanist of Montreal Botanical Gardens suspects that it was wrongly identified. Here is the note we received from him the week following judging:I've just checked our Bulbophyllum longilabre. It is misidentified.I have identified it as Bulbophyllum alticola on account of its flower morphology.It could be either of the following two species : B. dolichoglottis or B. alticola,It matches best B. alticola on account of its shallowly grooved pseudobulbs: Bulbophyllum alticola Schltr. is similar to Bulbophyllum dolichoglottis Schltr. in flower morphology, but differs in the smooth or shallowly longitududinally grooved pseudobulbs (versus obtusely to sharply 4-(-5-)angled pseudobulbs)Here are my references : alticolahttps://www.orchidsnewguinea.com/orchid-information/species/speciescode/16dolichoglottishttps://www.orchidsnewguinea.com/orchid-information/species/speciescode/155?longilabrehttps://www.orchidsnewguinea.com/orchid-information/species/speciescode/313
