Similar to C. paxii, but the plants somewhat taller (up to 5 m tall) and more or less glabrous; the petioles longer (up to 1.5 cm long); the leaves larger (up to 11 × 3.5 cm) and oblanceolate; and usually only 2 glands at the base of each petal in the male flowers.

Notes
The Zimbabwean material is generally more glabrous and its leaves are broader in relation to their length than is the case in the East African material, but is otherwise indistinguishable from it.Although C. robusta is reported from SW Tanzania in east Africa, I have only seen material from E Uganda, S Kenya and N Tanzania, where it is particularly associated with the large volcanic mountains.I have not seen material from Zambia, Malawi or Mozambique.The disjunct distribution might best be marked by describing the Zimbabwean plant as a distinct subspecies, but I prefer not to introduce another name into such a plastic group.Dame Alice and the Misses Godman 252 (BM) from Old Zimbabwe, 29.viii.1929, may belong here, but the male petals are entirely devoid of basal glands.
