This species is typical of Section Davidii in having oval-oblong leaves with a rugose surface. At the base of the leaves are brown scale-leaves. It is distinguished by having short hairs on both surfaces of the leaves but lacking longer septate hairs. The leaf margin is hydathode-dentate as per the original description though this is difficult to see on the herbarium specimens. It is worth noting that the KEW specimens were previously labelled P. ovalifolia and that P. ovalifolia and P. davidii are closely related to P. epilosa.
