Bulbophyllum is a very diverse genus and several Asian species like this are very remnicent of orchids from the americas. The three large sepals on Bulbophyllum stormii give the flower a look very similar to smaller Masdevallia species we grow such as Masdevallia herradurae (below) indicating some interesting parallel evolution.
Bulbophyllum stormii is native to Malaysia and is found from 1000-2000m altitude and we find that it enjoys warm shady conditions in our Warm Asia section (min 17C)
Flowers on Bulbophyllum stormii are 4cm across and very large relative to the size of the plant with its single 2cm leaves and tiny pseudobulbs. We grow the species mounted and it scrambles around forming a mat or ball of plant over time. This species is attractive when not in flower because of the grey green soft leaves.
We showed how we mount plants like this in a previous post here if you are interested.
