FIGURE 1. Rhizome and pseudobulb morphology in Bulbophyllum section Polymeres. a–b: New shoots emerging from a node along the rhizome (a), or the basal node of the pseudobulb (b) without being fused to the rhizome or pseudobulb any further than the node from which they originate (in b pseudobulb flanges are clasping the rhizome). c–e: New shoots emerging above the node from which they originate, because they are fused to or perforating the pseudobulb along part of the length of the latter. Rhizome sections are white, pseudobulbs green and flower buds red. Drawn by © J.J. Vermeulen.
