SOME NEW LEGUMINOSAE

A. D. E. ELMER. 
—O— 
Luzonia n. gen.—This new genus is nearest related 
to Canavalia from which it is chiefly distinguished by its 
nearly equal 2-lipped calyx; corolla not much exerted, with 
wings and keels nearly equalling the banner. Its leaves 
are suggestive of Canavalia, but the woody nature and the 
slender spicate inflorescence of our specimen are different. 
The characters of the calyx and the corolla debar it from 
being considered a Dioclea or Pueraria. 
Luzonia purpurea n. sp.—A scandent and widely spread- 
ing shrub, at most 10 m. high. Stems terete, 3 to 5 cm. 
thick, flexible, its yellowish porous wood filled with water; 
bark brown, thinly checked toward the base, lenticelled; 
branches rather many, the ultimate ones greenish brown, 
covered with light gray lenticels. Leaves alternate, ascend- 
ing, submembranous, lucid dark green above, duller beneath, 
glabrous, trifoliate and articulate; the lateral leaflets inequi- 
lateral, base rounded, apex abruptly terminating to a short 
acumen, elliptic or the terminal leaflet broadly obovate, in 
the fresh state dorsally recurved, from 5 to 15 cm. wide, 
7 to 18 cm. long, the terminal leaflet usually larger; pet- 
iole about 1 dm. long, extended and bearing the terminal 
leaflet, glabrous except the articulate thickened base; the 
short axillary gland subtended by 2 acuminate 4 mm. long
