Synonyms:	Agathisanthemum angolense Bremek. Agathisanthemum bojeri Klotzsch subsp. australe Bremek. Oldenlandia bojeri (Klotzsch) Hiern
Common names:
Frequency:	Frequent
Status:	Native
Description:	Branched, shrubby perennial herb, 25-150 cm tall. Young stems densely velvety, becoming hairless when older, often with brownish bark peeling off. Leaves opposite but often appearing whorled due to short, undeveloped shoots at most nodes, subsessile, narrowly lanceolate-elliptic to ovate-oblong, 1.2-6 cm long, hairless or slightly rough above, velvety on the veins beneath. Stipules finely velvety, sheath-like, up to 4.5 mm long with up to 5 fimbriae, 1-6 mm long. Inflorescences in more or less lax branched terminal heads, although individual clusters within the inflorescence may be quite dense. Flowers distinctly heterostylous. Calyx lobes 1-3.5 mm long. Corolla white, creamy or greenish-white 2.5-5 mm long. Style 1-2 mm long in short-styled flowers, 3-5 mm long in long-styled flowers. Capsule 1-3 mm long.
Notes:	Two subspecies are said to occur (Verdcourt, 1989 in FZ 5-1: 108-110): subsp. bojeri, with laxer inflorescence, calyx lobes less than 2 mm long and leaf veins well spaced along the blade; subsp. angolense (Bremek.) Verdc. has more dense clusters in the inflorescence, calyx lobes 2-3.5 mm long and leaf veins mostly basal. As these characters frequently overlap and also distribution and altitude differences, as given in FZ, are inconsistent to say the least, we will show this species as an aggregate until further work has been done to either separate the subspecies more clearly or rather, taxonomically combine them.
Derivation of specific name:	bojeri: after Wenceslas Bojer (1795/1797-1856), Czech naturalist, horticulturist and botanist at the Imperial Museum at Vienna who collected extensively in Mauritius, Madagascar, Comoro Islands and on the East coast of Africa.
Habitat:	Various types of woodland, grassland, riverine forest and as a weed in old cultivated fields, often on sandy soils.
Altitude range: (metres)	Up to 1500 m
Flowering time:
Worldwide distribution:	Angola, DRC, Somalia, Kenya, Tanzania, Mozambique, Zambia, Zimbabwe, Eswatini, South Africa, Comoro Islands and Madagascar.
