Dicotyledons with Polypetalous Flowers — Passiflorea . 
Calyx in Passion-flower with a short cup-shaped tube ; in Tacsonicc with a cylindrical, often long tube. 
Stamens in Passion-flower 4-5, the filaments adnate below to the stalk of the ovary; anthers versatile. 
Ovary in the same on a distinct stalk (gynophore), 1-celled, with 3 spreading styles. 
USES, &c.—Several species of Passion-flower, including the Granadilla (Passiflora qiiadrangularis), bear pulpy 
agreeably acid fruits, eaten in the West Indies and Tropical America. The root, foliage and flowers, on the other 
hand, are often dangerous, and afford preparations of medicinal repute in America. Several species and garden 
varieties or hybrids of Passion-flower, chiefly Passiflora ccerulect, P. kermesina , P. racemosa , P. Bctnksii of Queensland, 
and their derivatives, and a few species of Tacsonicc , are well-known beautiful climbers of our plant-houses.
