PERISTROPHE Nees. 
Peristrophe lancifolia sp. nov. 
Herba erecta vix vel parce ramosa, sparse strigosa; foljis membran- . 
aceis, anguste lanceolatis, acuminatis, usque ad 20 em longis, 2.5 cm 
latis ; foliis floralibus oblongis vel oblongo-lanceolatis, acuminatis ; corolla 
alba, 5 cm longa. 
An erect herb about 50 cm high or less, usually unbranched. Stems 
green, longitudinally sulecate, about 2 mm in diameter, glabrous, or the 
younger parts slightly appressed-strigose. Leaves lanceolate or narrowly 
lanceolate, 12 to 20 em long, 1 to 2.5 em wide, entire or very slightly 
undulate, gradually narrowed upward to the long, slender, acuminate 
apex, the base also narrowed, acute or acuminate, somewhat shining 
when dry, the upper surface dark-green, the lower surface pale-green, 
both surfaces with numerous, scattered, oblong cystoliths, the lower also 
minutely white-puncticulate and slightly appressed-strigose on the midrib 
and nerves; lateral nerves about 9 on each side of the midrib, ascending, 
anastomosing and forming a nearly straight submarginal nerve, the 
secondary nerves and reticulations lax; petioles 5 mm long or less, stri- 
gose. Peduncles few, 2.5 cm long or less, terminal and in the upper 
axils, strigose, few-flowered. Floral leaves 2, unequal, oblong to oblong- 
lanceolate, acuminate, 2.5 to 3.5 cm long, more or less strigose, especially 
on the margins. Flowers white, congested, each subtended by one or 
two linear-lanceolate, more or less hispid, long-acuminate bracts about 2 
em long, 2 mm wide, and by two or three similar but smaller bracteoles. 
Calyx-lobes similar to the bracteoles, subequal, about 8 mm long, hispid. 
Corolla 5 cm long, the tube slender, 2.5 cm in length, one lip entire, 1.5 — 
em broad, the other somewhat narrower and shortly 2-toothed at the- 
apex. Filaments slightly hirsute; anthers 2-celled, the upper cell about 
3.5 mm long, the lower 2 mm long, muticous. Style minutely bifid.
