34171. Pterygocarpus floribundus (Meyer) Stuntz. 



(Dregea floribunda Meyer, Commentariorum de Plantis Africae Austra- 

 lioris, vol. 1, fasc. 2, p. 199, 1837.) 

 Seeds of this asclepiadaceous plant from South Africa were received under 

 the name Dregea floribunda Meyer. The generic name Dregea had, however, 

 been used by Ecklonand Zeyher in June, 1836 (Enumeratio Plantarum Africae 

 Australiae Extra tropicae, p. 350) for certain umbelliferous plants now consid- 

 ered to belong to Peucedanum. It is therefore necessary to adopt the generic 

 name Pterygocarpus, published by Hochstetter in 1843 (Flora, vol. 26, bd. 

 1, p. 78). The type species of Hochstetter's genus is P. abyssinicus, a plant 

 congeneric with P. flx)ribundus. 



34172. Oncoba kraussiana (Hochst.) Planchon. 



Distribution. — A much-branched shrub with large white flowers found in the 

 woods in the vicinity of Durban, in Natal, South Africa. 



34173. OSTEOSPERMUM MONILIFERUM L. 



Distribution. — A diffuse shrub with bright-yellow flowers found along the 

 coast of South Africa from Natal to Cape Colony. 



34174. OxYANTHUS PYRiFORMis (Hochst.) Skeels. 

 (0. nMtalensis Sond.) 



See S. P. I. No. 31856 for previous introduction. 



34175. Pavetta revoluta Hochst. 



"A large shrub or small tree, smooth, free flowering, and apparently confined 

 to the coast. On the coast dunes from Port Elizabeth to Natal, scarce, and of 

 no economic use." {Sim, Forest Flora of Cape Colony.) 



Introduced for use as an ornamental in Florida. 



34176. PsYCHOTRiA CAPENSis (Eckl.) Vatke. 



"Usually a shrub, sometimes a tree, up to 10 to 15 feet high, with 3 to 6 

 inches stem diameter, and with crooked and forked timber. A common Natal 

 shrub of no economic use." {Sim, Forest Flora of Cape Colony.) 



Introduced for use as an ornamental in Florida. 



34177. BosciA UNDULATA Thunberg. WMte ironwood. 

 ( Toddalia lanceolata Lam.) 



"A large evergreen tree, often 2 to 5 feet in diameter, with a clean, tall stem 

 in high forests; frequent also as a bush or small, spreading tree in scrub forests. 

 Flowers from September to December, according to locality and season; fruit 

 ripens in autumn; 8,000 dry fruits weigh 1 pound and contain about 30,000 

 seeds. The seeds germinate easily, and the cultivation of the tree is simple. 

 Timber white, close grained, tough, hard, and hea\'y. Usually to be had 

 sound in the mountain forests up to 2 feet diameter and with 10 to 20 rings 

 to the inch. Used mostly by wagon makers. In toughness, it is the ash of 

 the South African forests." {Sim, Forest Flora of Cape Colony.) 



34178. TuRRAEA OBTUSIPOLIA Hochst. 



"A free-flowering shrub, 3 to 5 feet high, common on the dunes along the 

 coast of Cape Colony and Natal. It is never large enough to be of economic 

 value further than its use in holding fully exposed sea dunes; its showy flowers 

 and seeds make it worth cultivation where it will grow.. Flowers during early 

 summer, fruits in autumn.'- {Sim, Forest Flora of Cape Colony.) 



34179. TURRAEA HETEROPHYLLA Smith. 



See 31863 for previous introduction.
