14. STRUMPFIA Jacq.

Ovule solitary in each cavity, erect, anatropous. Fruit a drupe with 1 or 2 stones. Seeds 
erect, oblong. Testa membranous. Endosperm fleshy. 
1. Strumpfia maritima Jacq. A low much-branched shrub, rarely 9 dm. tall, the 
foliage minutely pubescent, the branches conspicuously short-jointed. Leaves in whorls 
of 3; blades leathery, firm, linear or linear-elliptic, 1-2.5 cm. long, strongly revolute, 
obscurely short-petioled: peduncles 2-10 mm. long, densely pubescent : hypanthium about 
1 mm. long during anthesis: sepals triangular or ovate-triangular, erect, acute: corolla 
white, pubescent, 3-4 mm. long; tube campanulate ; lobes lanceolate or oblong: drupes 
commonly 4-6 mm. in diameter, white or red. 
On sandy or rocky coasts, Keys of Florida. Also in the West Indies. 
15. PSYCHOTRIA L. 
Shrubs or trees, or rarely perennial herbs or vines. Leaves opposite or rarely whorled : 
stipules sometimes sheathing. Flowers perfect or rarely polygamo-dioecious, variously 
disposed in terminal or axillary clusters, not paired. Hypanthium short. Sepals 5, or 
rarely 4 or 6, mostly deciduous. Corolla white, pink, green or yellow, tubular, funnelform 
or campanulate : tube straight: lobes 5, or rarely 4 or 6, valvate. Stamens as many as the 
corolla-lobes, adnate up to the throat or mouth of the corolla-tube : anthers attached at the 
base. Disk various. Ovary 2-celled. Ovules solitary in each cavity, erect, anatropous. 
Fruit a small berry or drupe, often ribbed. Seeds erect. "Testa thin. Endosperm some- 
times ruminated. 
Stipules distinct: corolla-lobes as long as the tube: leaf-blades pubescent beneath. 1. P. tenuifolia. 
Stipules united and sheathing: corolla-lobes shorter than the tube : leaf-blades glabrous. 2. P. undata. 
l. Psychotria tenuifólia Sw. A low branching shrub, 3-12 dm. tall. Leaf-blades 
narrowly oblong or elliptic or elliptic-lanceolate, 8-15 cm. long, acuminate at both ends, 
undulate, pubescent beneath, often with conspicuous lateral nerves beneath: cymes few- 
flowered : hypanthium about 1 mm. long during anthesis: sepals broadly deltoid or tri- 
angular: corolla funnelform, 2-2.5 mm. long; lobes lanceolate or oblong-lanceolate, as 
long as the tube: fruits oval or oblong-oval, 5-6 mm. long. 
In rich woods, peninsular Florida. Also in the West Indies. 
2. Psychotria undàta Jacq. A widely branching shrub, or a small tree sometimes 
9 m. tall. Leaf-blades oval, elliptic or elliptic-lanceolate, 6-15 cm. long, acuminate at 
both ends, glabrous, short-petioled : cymes open: hypanthium 1 mm. long: calyx undu- 
lately toothed : corolla 2.5-3 mm. long, hairy in the throat ; lobes oblong or oblong-lanceo- 
late, shorter than the tube: fruits subglobose or ellipsoidal, 4-4.5 mm. long. 
In open woods, coast of Florida and the Keys. Also in the West Indies.
