Dear Sweedle Ji This group of small Dendrobiums including monticola, denudans, gregulus, peguanum etc are very tricky. The key is based on the presence of callus on the labellum. But with the help of proper leaves also you may get some help. Peguanum has thicker leaves with leathery texture. Monticola has thinner, narrower leaves wth papery texture. The image shared before looks like monticola to me. But your picture looks like peguanum to me. Thicker leaves are evident. Its always good to have complete picture of the plant. Peguanum has broader and conical pseudostems, where as most of the rest have elongated and narrower pseudostems.
