Welwitsch states that the plant is frequently cultivated in gardens 

 near the river Bengo : with reference to this statement Ficalho, PI. 

 Uteis, p. 189 (1884). considers that there may have been some con- 

 fusion between this species and wild forms of C. Melo L. ; this is the 

 more probable, inasmuch as Welwitsch included under the same No. 

 a specimen from Imbondeiro dos Lobos, in the same district, cultivated 

 26 March 1858, which he called C. Melo L.
