O. atropurpurea. Forester Fegen records this as a “ small shrub growing to edge of 
Maseko Forest and which is very plentiful. It has flowered and fruited very sparingly 
this year (1915) and fruiting specimens are scarce. The leaves, although identical in shape, 
are smaller on every specimen than those of O. natalitia. It is also found at Notinsela.. 
Galls are nearly always present, and the plants, like O. natalitia, are confined to the edge 
of the forest.’’* ê 
O. pulchra. A small or large tree, 6-20 ft. high. The trunk is smooth and usually white, 
which makes the recognition of this tree in the veld easy. It is usually in flower late in 
September, and at the end of October the sepals take on a red colour which makes the 
species so conspicuous. The young fruits are then forming, and they mature in December. .. 
The flowers are sweetly scented ; at first the sepals are bright green, then change to olive- 
brown and red. The seeds are said to be poisonous.
