P. pallens?

[naoki]

First blooming of this plant. I got it from Olympic Orchids as a small seedling. Is this really P. pallens? The shape of the lip has some resemblance to P. fasciata.

Update: I dissected one flower, and I now think this is really P. pallens.

Side view of the lip (one of the lateral lobe is removed to show the callus):

Top view of the mid lobe (top) and the detached lateral lobe (bottom) of the lip of P. pallens:

Two sets of the callus can be seen. The posterior callus (closer to the place where the lip is attached to the column/flower) is a distinguishing character of P. pallens. P. pallens has a clean two-tipped posterior callus. The other related species such as P. fasciata, P. hieroglyphica, P. lueddemanniana have more complex (bunch of sticks/hairs) posterior callus. So this plant seems to match well with P. pallens.

Looks very much like pallens. Interesting, some flowers of this species are shown with a tri-lobe lip & others with a single lip.

Thanks all, I just updated the original post by adding two more photos. I think this is P. pallens.

Roy, thank you for the info. You are right, this species seems to have some variation within the species.

Bloom is gorgeous and I also love the areal roots.
