IDM Zimbabwe - Northern Woodland Sugarbush - Protea angolensis

Mountain Sugarbushes tend to have the largest heads (over 70 mm long). Similarly, their leaves are large (100-200 mm long) and either hairy or hairless. The involucral bracts may be either hairy or hairless, and are usually slightly longer than the flowers. The petals are longer than 45 mm. The involucral bracts tend not to close after flowering (and thus do not protect the fruits as in other proteas). The involucral receptacles rise in the centre to a distinctive point.

Protea angolensis - Northern Woodland Sugarbush

Variable in habit from multi-stemmed shrubs to 0.5m tall to trees to 3m tall with a single stem. Leaves 100-160 mm long, 20-80 mm wide. Flowerhead solitary, 70-100 mm long. Petals with tube with short hairs. Style 60-70 mm long. Only the white flowered form is known from Zimbabwe.

Protea angolensis Distribution

Protea angolensis var. angolensis Dwarf Northern Woodland Sugarbush

Pr ango a: a dwarf plant to 1m tall, with a rootstock. Leaves 20-60mm wide. Involucral bracts rapidly maturing to hairless. Perianth tips usually hairy, white.

Found in open grasslands and on the edges of dambos. By far the most commonly encountered var..

Protea angolensis var. divaricata Northern Woodland Sugarbush

Pr ango d: small tree to 4m tall, with a single stem. Leaves 30-100mm wide. Involucral bracts with silky hairs. Perianth tips hairless, white.

Found as an undershrub in Brachystegia Woodland, Brachystegia-Uapaca-Parinari Woodland, and secondary bush.

Beard noted hybrids between Pr welwitschii and Pr angolensis. It should be fun to try and determine if these still persist in the populations in which they were found. The hybrids should be hairy and large. Unfortunately, the locality details are rather vague. They are:
1. Near Harare Central Divistion –1954 (Rodin 4260)
2. Farm Tanglewood, Ruwa District – 1958 (Miller 5340)
3. Harare District, sandveld – 1952 (Whellan 36008).
