1. There is some difference between the material from Sumatra and Borneo and that of the Philippines and New Guinea. The former has smaller leaves and flowers, often (especially Sumatra) hair tufts on the leaflets beneath, usually thyrsoid inflorescences, a (sub)glabrous disc, always 6 stamens, and the stigma distinctly lobed; the latter is more coarse, lacks hair tufts on the leaflets, has less branched inflorescences with fewer and nearly always solitary flowers, the disc is always densely hairy, and the number of stamens is often 7.
2. The name Xerospermum thorelii Pierre was illegitimate as it was mentioned under the plate only, whereas in the accompanying text Cnemidiscus thorelii was used (ICBN 1972, art. 34).
