Small to medium-sized climbing or procumbent vines with perennial stems from woody perennial rootstocks or taproots, antrorsely appressed-puberulent more or less throughout, with unicellular, curved or occasionally erect trichomes, and sometimes sparsely to densely pubescent with longer unicellular, rarely multicellular, curved trichomes. Stems terete to somewhat compressed and two-edged, the shoot apex erect. Leaves simple, commonly bearing nectaries on the petiole (except in Passiflora eglandulosa  and Passiflora mcvaughiana  ); petioles sometimes canaliculate, biglandular (rarely eglandular or with only a single gland) with opposite, subopposite or alternate, discoid, cupulate, obconical or capitate extrafloral nectaries; laminas unlobed or 2- to 3-lobed (rarely 5-lobed), often exhibiting heterophylly, sometimes cordate at base, entire (very rarely crenate), venation palmate, variegated or not, peltate or not, sometimes bearing small abaxial disciform or crateriform nectaries present ± submarginally between the major veins (very rarely associated with leaf crenations). Stipules setaceous to foliaceous, persistent, narrowly to widely ovate, rarely oblong or obovate, symmetrical or sometimes asymmetrical, entire, not glandular. Tendrils simple, lacking adhesive disks, straight or slightly curved during development at shoot apex. Inflorescences sessile in leaf axils, the pedicels solitary or paired, collateral with tendril, articulate, the articulation generally several mm below the flower; secondary inflorescences sometimes present as condensed axillary or usually terminal shoots, determinate or usually indeterminate; bracts 1-2 or lacking, narrowly ovate to entire. Flowers erect or rarely ± horizontal, greenish yellow sometimes with purplish to reddish markings, or red, hypanthium usually shallow, occasionally the calyx basally connate into a conspicuous floral tube; sepals ovate-triangular, not corniculate, greenish yellow, red, or rarely whitish; coronal filaments in 2 series (rarely 1 or 7 series), greenish yellow, sometimes with yellow and/or purple to red markings, or purple to red (sometimes very dark reddish purple), linear, often subcylindrical in cross-section, inner filaments usually capitate; operculum connate, membranous, plicate (very rarely denticulate), incurved or rarely semierect and laying against androgynophore; nectary trough-shaped or rarely absent, commonly lacking or possessing a very inconspicuous nectar ring or annulus; limen adnate to floor of hypanthium or rarely absent (in Passiflora viridiflora  the limen present as a shallow cup around base of androgynophore), the edge commonly erect and inclined toward the nectary, rarely curved toward the androgynophore. Staminal filaments with the free portions actinomorphic; anthers commonly extrorse at anthesis with their axes maintained parallel, rarely perpendicular, to the filament or rarely the anthers move only slightly from the original introrse position, remain introrse, and dehisce distally (upwards); pollen ellipsoid to spherical, 6-syncolporate. Carpels 3; ovary ellipsoid or globose, rarely slightly ovoid, obovoid or fusiform, glabrous or rarely densely pubescent with curved, unicellular or rarely multicellular trichomes; styles slender, less than 1.5 mm in diameter; stigmas capitate, depressed-ovoid. Fruit a one (rarely) to many-seeded purple or very dark purple berry, arils pale-translucent covering approximately 3/4 of the seed. Seeds more or less compressed, often beaked at chalazal apex, reticulate-foveate. Germination epigeal. Chromosome numbers: n = 6 (12, 18). Commonly lacking c-glycosylflavones and usually containing flavonol 3-O-glycosides. Fig. 22
