Prom South Africa, Presented by Prof. J. Burtl Davy, government agrostologist 

 and botanist, Transvaal Department <>i 'Agriculture, Pretoria. Received August 

 1. L910. 

 Sec!- of the following: 



28662. Acacia mtakunensix Burchell. 



"This was collected 70 miles southeast of the type locality. I have not 

 been able to learn that the wood has any special economic value, but the tree 

 is ornamental and stands considerable drought, with some frost." (Davy.) 



Distribution. — The vicinity of Litakun in Bechuanaland, South Africa. 



28663. Lebbckia cuspidosa (Burch.) Skeels. 



(Spartium cuspidosum Burchell, Travels, vol. 1, p. 348, 1822.) 



{Genista cuspidosa DC, Prodromus, vol. 2, p. 147, 1825.) 



(Stiza psiloloba E. Meyer, Commentariorum de Plantis Africae Australi- 

 oris, p. 32, 1835.) 



(Lebeckia psiloloba \Yalp., Linnaea, vol. 13, p. 478, 1839.) 



This South African leguminous shrub is reported by Harvey (Flora Capensis, 

 vol. 2, p. 84, 1861-62) from "Near Uitenhage," and it was originally described 

 from between "Gattikamma" (white water) and "Klaarwater," now known 

 as Griquatown, and apparently near the latter locality. Burchell says in 

 regard to it : "In one part, toward the end of our journey, we passed abundance 

 of a handsome shrub, from 5 to 7 feet in height, covered with showy yellow 

 flowers, but quite destitute of leaves, and even by this light easily to be dis- 

 tinguished as a plant which had not been anywhere seen before. It was com- 

 pletely armed at all points, its green leafless branches being terminated by a 

 spine as sharp as a needle." 



De Candolle in the Prodromus restricted the use of the generic name Spar- 

 tium to a single species of the Mediterranean region, S. junceum, and referred 

 this South African plant to Genista. The species was apparently again de- 

 scribed by E. Meyer under the name Stiza psiloloba, and since Stiza is not 

 recognized as distinct from the earlier Lebeckia, Meyer's plant was placed in 

 that genus by Walpers. The original specific name published by Burchell, 

 though long in disuse, is here restored. 



"This is a nearly leafless, dense shrub, about 6 feet high, bearing ornamental 

 yellow flowers. It is very spiny and should be suitable for hedges. It comes 

 from the Kalahari, near Kuruman, and is likely to suit dry, warm reigons."
