Distribution.

The principal or only subspecies in Ecuador and Peru extending south into Bolivia: Ecuador (Spruce 5810); Peru (Thomas 3/1, Mathews 377); Bolivia (Badcock 607, Beck et al. 31637), northern Argentina (Fortunato et al. 4648). 2200-2880 m.

Notes.

The name Convolvulus incanus was, and still is ( Hyam 2011: 554), commonly misapplied to Convolvulus equitans from North America, although it is clearly indicated that the type was collected by Dombey; perhaps it was grown from seeds with the same origin as those from which the type of Convolvulus hermanniae was grown.
