Passiflora affinis is similar to P. lutea in leaf shape and flower appearance. However, P. affinis has nectaries on the abaxial surface of the leaves, which are absent in P. lutea. Passiflora affinis also has floral bracts, and flowers greater than 25 mm in diameter with clavate to capitate, sinuous outer corona filaments more than 10 mm long. Passiflora lutea lacks floral bracts and has flowers less than 25 mm in diameter with apically unornamented, typically straight outer corona filaments that are usually less than 10 mm long.

In the flora area Passiflora affinis is restricted to central Texas, where its leaves are often appropriately shaped like cowboy hats. E. P. Killip (1938) erroneously suggested that it is native to New Mexico, based upon the misinterpretation of herbarium label data (D. H. Goldman 2004).
