Note
|
While I have placed this species in Orthipomoea, I am not certain it belongs here. It is similar to the I. lindenii complex of Eriospermum and may belong there; however, Standley (Contr. U. S. Natl. Herb. 27: 312-317. 1928) stated that the seeds are finely pubescent. The pubescence type suggests affinity here and not with Eriospermum.
