Discussion:

Type. Flowers purple-blue, locally abundant in Sabana de Moyo, right hand bank of Rio Orinoco, 10 k m above mouth of Rio Ventuari, alt. 125 m, 31 Jul 1959, Amazonas, Venezuela, J. J. Wurdack & L. 8. Adderley 43689 (holotype NY). Paratype. Flowers purple-blue, apparently rare, Cacagual Savanna, alt, 135 m, Rio Atabapo, 13 Sep 1957, Vaupes, Colombia, Maguire, Wurdack & Keith 41439.

The two populations, treated as varieties here, are quite distinct, and in their respective localities quite uniform. Should they be found to retain this distinction while occurring in the same locality, it perhaps would then be better to consider them to be distinct species.
