I. ocHRACEA G. Don, Gen. Syst. iv. 270. Convolvulus ochraceus 

 Lindl. Bot. Reg. t. 1060 (1827). 



Angola ; Loanda, Welivitsch, no. 6245.

 ivitsch, nos. 6175, 6176. 



There has been considerable confusion with resppct to the Wel- 

 witsch numbers 6174, 6175, 6176, and 6245, which have been 

 variously distributed between I.ochraceaDou, LofihthahuantliaMoW. f., 

 and /. kmtrorarpa Hochst. In the Catalogue of Welwitsch Plants, 

 i. 737, Mr. Hiern puts them together under /. ochracea Don, although 

 Welwitsch himself considered that they included two new and distinct 

 species. 



No 6245 formed part of the original I. ophtludmanfha of Hallier, 

 since united by liim in part with I. acanthocarpa Hochst., and in 

 part with I. ochracea Don, the Welwitsch number falliny^ under the 

 latter. This is no d 'ubt its true pbice, as h agrees with tne original 

 fi«!;ure in the But. Reg. (t. 1060, Coiivoliulus ocitracnis Lindl.). It 

 differs from the other three numbers in its larger flowers (the 

 corolla measures 4 cm. long) and acute sepals.
