and eastern Queta, not uncommon, flowering from August to December 

 and fruiting from November to February ; at Sange, Nov. 1854 and 

 Feb. 1855 ; at Carengne, Sept. and Dec. 1855. The powder of the 

 dried leaves is remarkably antiscorbutic. The native name is " Catete 

 BuUa." No. 1632. Fruiting calyx simulating a pericarp, f in. long ; 

 carpels 4, resembling seeds, surrounded with a long fringe, altogether 

 about i in. long. Among the Queta mountaihs ; fr. Aug. 1856. Coll. 

 Caep. 807. 



PuNGO Andongo. — An undershrub, 2 to 3 ft. high ; leaves obtusely 

 emarginate at the apex. In the less dense woods near the prsesidium 

 in the direction of Catete, sparingly ; in young fl. March 1857. 

 No. 1631. At Mopopo ; fr. 30 April 1857. Coll. Caep. 852. 



In Golungo Alto this plant is very abundant ; there and also in 

 Pungo Andongo it is called " Catete Bulla " ; the tender shoots and 

 the leaves, dried and reduced to a powder, and administered either in 

 bulk or in the form of a saturated infusion, were at times recommended 

 to Welwitsch by the negro doctors as furnishing one of the most 

 efScacious remedies for scorbutic diseases especially for those of the 

 mouth ; he, however, had no opportunity of convincing himself of 

 any salutary effects in such cases. See Welw. Synopse Explic. p. 28. 

 n. 62 (1862).
