Passiflora mixta
Passiflora mixta, from the family Passifloraceae is also known as curuba (in Colombia), curuba de indio, curuba de monte, curubita, parcha (in Venezuela), and taxo (in Ecuador). Originally, it derived from the monophyletic Passiflora subgenus Tacsonia. Passiflora mixta is endemic to the Americas. A perennial vine, the Passiflora mixta is pink to orange-red in color.[1] Description Passiflora mixta can be identified by its large pink flowers and trilobate coricaeous leaves, which are tubular in shape and protrude from its branches. It has a hairy elongated bract and 7–15 cm long (2.8–5.9 in) hypanthium (flower tube) that contains a narrow nectar chamber. The ovaries, anthers, and stigmas are located anterior to the hypanthium near the androgynophore. The species is capable of producing fruits and flowers that remain open for 3 to 5 days by producing half-pendant, horizontal, or erect flowers. The species is wild, collected, and an important genetic resource for banana passionfruit breeding.[2] Morphology
PollinationThis species of Passiflora is pollinated by the sword-billed hummingbird (Ensifera ensifera), which is the only living species in its genus. The hummingbird is found throughout the northern Andes and is identified by its extremely long beak, longer than its entire body. The long beak allows the bird to reach nectar at the bottom of the plant's long corolla tubes.[4][better source needed] DistributionPassiflora mixta ranges from Venezuela to Bolivia, and has been naturalized in Africa and New Zealand. It is restricted to highland areas between 1,700 and 3,700 m (5,600 and 12,100 ft) above sea level. The species can withstand disturbances and is more prominent in dryer environments and lower altitudes than other species of Tacsonia. It grows along the edges of forests and along the margins.[1][2][5] References
