Passiflora tarminiana
Passiflora biflora
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).

In the flora area, Passiflora biflora occurs only in southeastern Florida, where it is locally abundant and often an aggressive weed.
