Discussion | Passiflora tarminiana is sparingly naturalized in the eastern San Francisco Bay area (F. Hrusa et al. 2002) and southward along the coast to San Luis Obispo County, in areas of minimal summer drought. This species was recently described, and is commonly confused with Passiflora mollissima (Kunth) L. H. Bailey [now usually recognized as P. tripartita var. mollissima (Knuth) Holm-Nielsen & P. Jørgensen]. Many reports of P. mollissima in agricultural, horticultural, and weed-science literature actually apply to P. tarminiana. An attractive plant with large, edible fruits (T. Ulmer and J. M. MacDougal 2004), it is an extremely aggressive weed in Hawaii (A. M. La Rosa 1984, as P. mollissima) and other areas where it has been introduced in the Old World tropics and subtropics. The species is unlikely to become a widespread weed in the continental United States because it cannot survive frost nor occasional desiccation. A similar, closely related species, Passiflora mixta Linnaeus f., is a rare escape in San Francisco, California; it can be distinguished from P. tarminiana by its angular young stems, persistent stipules (deciduous in P. tarminiana), and a floral tube 80–110 mm deep, 1.6–2.6 times the sepal length (1.3–1.6 times in P. tarminiana).

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).
