    Looks like plant size is about the same?

    The eberhardtii plant isn't in the pic that's another species in the background. The eberhardtii is quite a bit bigger than corolliferum plant.

    Have you taken a close look inside each of the flowers to see if there are differences?

    I can't see enough detail in the second one to guess. Do they look the same to you?

    I know my little macro lens for t fit on this phone. I'll have to rig something this weekend to get a better shot. They do look quite similar up close.

    Very nice! AFAIK eberhardtii is currently considered a synonym/member of the longiflorum group, whereas corolliferum is still recognized as a distinct species. Vegetatively they seem pretty distinct, in Orchidaceae sometimes a better indicator of relation than floral form, which seems to evolve fast and parallel/converge with other species in response to pollinator selection.

    It's with longiflorum! I didn't know that I thought eb and picturatum were synonymous

    Your final image looks very much like Bulbophyllum corolliferum.which is quite variable, especially in the colour of the flowers.
    Scape 7- 10cm long with 12 or more flowers. Dorsal sepal to 7mm long, hooded, suddenly narrowed to a slender tip, edged coarsely
    purple-hairy; lateral sepals 1cm to 1.2cm long, 3mm wide, upper edges joind from near the base to the blunt tips, the whole curved so as to form almost a quadrant of a circle when seen from the side. Petals a little shorter than the dorsal sepal,similarly fringed. Lip apex normally tipped yellow.

    Your first images show flowers that look similar to B.eberhardtii, but seem to lack the robustness of that species. I know that this species is considered to be a synonym of B. longiflorum. Perhaps we can seperate your species against B.longiflorum by comparing the lateral sepals of B.longiflorum which are connate with the lower edges forming a common slender blade for the greater part more or less parallel edges, only narrowing quite near the bipartite lip. Staying with longiflorum, the pustules towards the tips of the hooded dorsal and the pustules towards the tips of the petals make for a more positive identification, hope this helps.
