Passiflora pallida
Passiflora tenuiloba
The leaves of Passiflora pallida show variation in lobe number, from juvenile to adult plants, and within and among individuals, with both unlobed and three-lobed leaf forms most common. In Texas, leaves on mature plants are always symmetrically three-lobed; in Florida, leaves can be unlobed, symmetrically three-lobed, or asymmetrically two- to three-lobed. Passiflora pallida is also self-compatible, an unusual feature in the genus.
In peninsular Florida, Passiflora pallida is widespread and locally common to occasionally weedy. In Texas, it is relatively uncommon, known only from the extreme southernmost part of the state and from a single disjunct population about 150 miles northward in Refugio County (S. R. Hill 1981).
Traditionally synonymized under Passiflora suberosa in our region (for example, D. S. Correll and M. C. Johnston 1970; R. L. Hammer 2002; R. P. Wunderlin and B. F. Hansen 2003), P. pallida is closely related to the larger-flowered P. suberosa and commonly is treated as conspecific with it worldwide. The hypanthium of P. pallida generally is 3–4 mm in diameter, with inner coronal filaments usually less than 1.5 mm and outer filaments less than 4 mm, whereas in P. suberosa the hypanthium generally is 4–8.8 mm in diameter, with inner coronal filaments usually 1.5–3.9 mm and outer filaments (2.5–)3–8.1 mm. Passiflora suberosa is native in
Mexico, the West Indies, and Central and South America, and has been widely introduced in tropical regions (weedy in Hawaii), but does not occur in the flora area. In regions where the two species naturally co-occur, P. pallida generally is found at lower elevations than P. suberosa. These two species and close relatives were reviewed by K. E. Porter-Utley (2003).

E. P. Killip (1938) and W. C. Martin and C. R. Hutchins (1980) incorrectly indicated that Passiflora tenuiloba is native to New Mexico. This is based upon the misinterpretation of confusing labels on old specimens (see D. H. Goldman 2004).
Passiflora tenuiloba has the most variable leaves of any species in the genus. They vary considerably in texture, color, indument, lobe length and number, and petiole-gland size and shape, not only between populations but also within individual plants.
