Passiflora ornithoura – Rare Bird-Tail Passionflower


Passiflora ornithoura Mast. ex J.D.Sm. is a fascinating member of subgenus Decaloba, highly valued by collectors for its unusual foliage and strikingly patterned flowers. Its leaves show a distinctive bilobed shape, almost like a “V-sign” formed by two slender fingers, with subtle variegation and folds that give the plant a sculptural quality. While its leaves are the main attraction, the blossoms deserve equal attention: small but colorful, they combine green and pale purple petals with corona filaments tipped in vibrant yellow.
 
● Notable Traits of Passiflora ornithoura


Leaf Form: Bilobed, tail-like leaves with fine folds and decorative variegation.
Flowers: Small blooms around 1.5 cm in diameter, displaying green and pale purple petals.
Corona Detail: Short filaments ending in vivid yellow tips add contrast to the flowers.

● Natural Habitat


Described by Masters and later formalized by John Donnell Smith, Passiflora ornithoura is native to Central America, where it inhabits warm, humid forests. Like other members of the subgenus Decaloba, it prefers shaded to semi-shaded conditions and scrambles through shrubs and understory vegetation in its natural range.
