Names
XYRIS Barteri N. E. Br. [family XYRIDACEAE]
Information
Leaves not seen. Peduncular-sheath 2 1/2 in. (or more?) long, terminated by a linear acute leaf 2 in. long, 2/3 lin. broad, glabrous. Peduncle 1 1/2–2 ft. long, 1/2– 3/4 lin. thick, somewhat compressed, 2-edged, hollow, glabrous, striate (from shrinkage?). Spike 3 lin. long, 2–2 1/2 lin. thick, ellipsoid or ovoid, 7–12-flowered. Bracts spirally imbricate one above another, 2 1/4–2 1/2 lin. long, 1 1/2 lin. broad, coriaceous, elliptic or elliptic-oblong, obtuse, entire, sometimes apiculate, light chestnut-brown, the inner with a stout usually dark green keel; nerves very indistinct, very slender and irregular. Lateral sepals 1 3/4–2 lin. long, 1/2 lin. broad, falcate-lanceolate, obtuse, boat-shaped, brown along the back, fading to light yellowish-brown on the sides; keel winged, minutely ciliolate along the middle part only, not produced at the apex. Flowers not seen. Capsule obovoid, trigonous.
Distribution
Niger Upper Guinea Nupe, Barter!
Notes
Allied to X. angularis, N. E. Br., but differing in its compressed (not acutely angled) peduncles, the absence of a dorsal area on the bracts, and other characters.
