Petals almost as long as the sepals, obtuse, pink. Corona consisting of a purple band with a few pinkish tubercles or crenulations. Operculum white, recurved at the margin, subentire. Ovary 9 × 3 mm., oblong, sericeous-tomentose. Fruit 6–7 × 3–3·5 cm., oblong-ovoid, green when unripe, orange-yellow when ripe, softly pubescent.

Leaf-blades 3-lobed, the depth varying from about half-way to ± six-sevenths, in outline suborbicular, 5–11 by 6–13 cm., base truncate to cordate, 3(–5)-nerved from the base, membranous to thinly coriaceous, glabrous or subglabrous above, pubescent to various degrees beneath; lobes elliptic to lanceolate, 2.5–6 cm., top acute or up to 1.5 cm. acuminate; margin glandular serrate-dentate up to 2 mm.; petiole 0.7–2.5(–5) cm. Glands on petiole absent or mostly 2–5 pairs, minute, sessile or subsessile; blade-glands, except marginal glands and sometimes a small gland in the lobe-sinuses, absent. Stipules subcircular or obliquely reniform, either ± 2 mm. or ± 0.5(–0.9) cm. in diameter, finely glandular dentate, if small caducous. Inflorescences 1-flowered, the peduncle 1.5–5 cm., inserted beside a simple tendril 5–18 cm.; bracts and bracteoles 2–4 cm., acute-acuminate, connate for half-way to up to ± three-fourths, forming a tubiform involucre. Flowers 5–10 cm. in diameter, pinkish or pinkish red to pinkish orange. Hypanthium tubiform, (5–)6–9 by 0.5–1.5 cm.; sepals oblong, 2–5.5 cm., subobtuse, mucronate below apex. Petals oblong, 2–5 cm., obtuse. Corona a low lobulate edge at the throat of the hypanthium; operculum an inward curved membrane, at the base of the hypanthium. Androgynophore 6–10 cm.; filaments 10–15 mm., dilated; anthers 7–13 mm. Ovary oblong, 10–12 mm., pubescent; styles 10–15 mm. Fruit rather dry, ± ellipsoid, excluding the long gynophore 6–12 cm. long, softly pubescent, yellowish. Seeds many, ellipsoid, ± 6 mm.

Information For generic synonyms see Harms, and Killip, loc. cit.Mostly perennial climbing herbs to large lianas, rarely (not in Africa) shrubs or trees, glabrous or hairy, provided with tendrils. Leaves mostly alternate, unlobed to deeply lobed, palminerved or pinninerved, petiolate; margin mostly dentate, often with small gland-teeth; petiole with or without glands; blade-glands present or not. Stipules minute to large. Inflorescences sessile or peduncled, 1–many-flowered, with or without a simple tendril, or rarely flowers collected into pseudoracemes; bracts and bracteoles small to large, forming a conspicuous involucre or not. Flowers hermaphrodite, 5-merous; hypanthium saucer-shaped to cylindrical. Sepals and petals free, often brightly coloured; petals mostly resembling sepals, membranous, sometimes absent. Corona extrastaminal, variously shaped, simple or mostly composed of a usually complicated outer corona consisting of threads, and flat or plicate inner coronas, sometimes with the addition of a nectary ring or annulus. Androgynophore mostly distinct, 3 mm. or more; stamens 5(–8), free (or in some Asian species partly connate), in older flowers mostly reflexed; anthers dorsifixed, versatile, elliptic to linear. Gynophore absent or sometimes up to 7 mm.; ovary globose to fusiform; styles 3(–4), free or connate at base; stigmas capitate. Fruit usually indehiscent, ± baccate, often with coriaceous exocarp, globose, ellipsoid or rarely fusiform, containing many seeds.

Information Climbers or sometimes erect herbs, mostly provided with axillary tendrils (tribe Passifloreae), or erect shrubs or trees (tribe Paropsieae), glabrous or hairy, rarely thorny. Leaves mostly alternate, simple or compound, entire or lobed, often with glands on petiole and blade; stipules small, sometimes caducous. Inflorescences axillary, either cymose (Passifloreae), ending in 1–several tendrils or not, or racemose (Paropsieae); bracts and bracteoles usually small. Flowers hermaphrodite or functionally unisexual (then plants often dioecious or polygamous); stipe articulate to pedicel; hypanthium saucer-shaped to tubiform. Sepals 4–5(–6), imbricate, free or partially connate (Adenia in part), often persistent. Petals (3–)4–5(–6), imbricate, rarely absent. Corona extrastaminal, inserted on the hypanthium, various, composed of hairs, or of 1 or more whorls of thread-like processes or scales, or tubiform or cup-shaped, or absent (Adenia in part). Disk mostly extrastaminal, annular or composed of 5 mostly strap-shaped parts (Adenia), or absent. Stamens 4-many, inserted on the hypanthium or on an androgynophore, if few alternipetalous, free or partially connate; anthers 2-thecous, basifixed to dorsifixed, versatile or not, sometimes apiculate, opening lengthwise. Ovary superior, sessile or on a gynophore or androgynophore, 1-locular, 3–5(–6)-carpellate, with 3–5(–6) parietal placentas; ovules mostly numerous, anatropous; styles 1 or 3–5, very short to distinct, free or partially united; stigma capitate to subglobose, sometimes much divided (Adenia). Fruit a loculicidally 3–5-valved capsule, or berry-like. Seeds mostly compressed, enveloped by a membranous or mostly pulpy aril; funicles often distinct; testa crustaceous, mostly pitted; endosperm horny; embryo large, straight, with foliaceous cotyledons.
