Discussion | 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). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Passiflora filipes and P. lutea are morphologically similar and closely related (E. P. Killip 1938), yet they do not occur sympatrically. In the flora area, P. filipes is restricted to southernmost Texas; the southern range limit of P. lutea is at least 150 km north of the range of P. filipes. In addition to the relative lengths of middle leaf lobes, seed surface features distinguish these two species, with sharply and coarsely foveate seeds in P. filipes versus the more delicately and transversely sulcate seeds of P. lutea.
