With this species must be compared Nos. 3309 to 3314, mentioned 

 undeo V. undulata O. & H., some of which agree fairly well with a 

 specimen in Herb. Kew. from Angola collected by Monteiro and con- 

 sidered in the Flora of Tropical Africa iii. p. 276 as a form of the 

 latter species or perhaps a new species ; they occupy an intermediate 

 position between the two species with respect to the degree of acute- 

 ness of the involucral scales, and there are almost corresponding forms 

 in tropical Asia.
