Bolusanthus speciosus, Harms. I.e. 

 Lonchocarpus speciosus, Bolus in Journ. Linn. Soc. vol. sxv. p. 161 (1889). 



This remarkable and handsome leguminous plant was 

 collected by the late Dr. Bolus near the Komati Eiver Drift 

 in 1886, and described by him as Lonchocarpus speciosus. Dr. 

 Harms of Berlin, when examining a collection of Ehodesian 

 plants, came across the same species on which he founded 

 the genus Bolusanthus. The free stamens would indicate that 

 it is not a species of Lonchocarpus. 



Our illustration was made from material collected by 

 Dr. Pole Evans at Chunies Poort, Transvaal, in October, 1919. 

 The tree, which frequently reaches a height of 30-40 feet, is 

 locally known as " Van Wyk's Hout," or " Wild Wisteria/' 

 It is frequent along the northern foothills of the Zoutpansberg 

 range of mountains and in the low veld bush country along 

 the Selati River. When in full bloom it is one of the most 

 beautiful sights seen in the veld, and is a species which should 

 certainly be introduced into cultivation.
