This undescribed new species of Rhus is found, typically on cliffs, along the sides of the larger wadis draining south into the Noged plain. The leaves, which are always trifoliate, are bright green, smaller and not as glossy as those of Rhus thyrsiflora. It comes into new leaf at the onset of rain and drops its leaves in summer. The flowers appear in winter and are in little-branched panicles which are shorter than the leaves; in R. thyrsiflora the flowers are in open panicles which greatly exceed the leaves. Its fruits, which are similar to those of R. thyrsiflora are said to be sweeter and, unlike those of R. thyrsiflora, are not wrinkled when dry.
