IDM Swaziland - Common Transvaal Sugarbush - Protea caffra caffra
A solid black dot indicates where the species is found.
Protea caffra caffra - Common Transvaal Sugarbush has leaves 13-30 mm wide, with wedge-shaped bases. The flowerheads are 40-70 mm long and petal tubes are 10-14 mm long. It is very variable with many races - recognized by John Beard and sunk by John Rourke - of which the following occurred in the area:
PR CAFF is the most widespread and common protea in Swaziland. Half of our sites to date have Pr caffra present. But it is very poorly recorded, being regarded as "too common to be of importance". We definitely need more records for this species please look out for this species! We have good records for the west of Swaziland, although more data from the range extensions to the south of the country need to be obtained. Specifically herbarium records from Mbomwane (2631 CC) should be obtained for the Swaziland Herbarium. The following details are available:
Does the species not occur between the sites shown?
Despite the many range extensions, we still lack data from some herbarium records. These are for:
The latter two records from the Lebombo Mountains suggest that proteas could occur over much of the range in suitable habitat. Could this please be investigated.
Young Pr caffra plants are very similar to Pr simplex. Although adult Pr caffra are trees, they need to grow large enough to survive fires. Thus young plants form an underground rootstock and produce many stems, which are burned down with every fire, until stems are thick enough to "escape" fires and thus grow up into trees. The moment one branch is thick enough, the other basal branches are shed and the plant assumes its tree-like habit. It thus differs from Pr simplex, which never grows into a tree, and its thin branches usually burn in every fire. The easiest way to distinguish the two species is by the very thin stems in Pr simplex, and the much thicker stems in Pr caffra. The stems in Pr caffra are often branched seldom so in related species. Pr caffra may stay as a resprouter for decades until fire frequency and intensity allow escape into the tree form. Both differ from Pr parvula with its creeping stems laying flat on the ground.
