Tresine tomentella Standley, sp. nov. 
Shrub; branches slender, sparsely whitish-tomentose when young, glabrate in age; 
petioles 0.8 to 1.5 cm. long, tomentulose when young; leaf blades oblong-elliptic, 
elliptic, or oblanceolate-oblong, 12.5 to 21.5 cm. long, 3.3 to 6.5 cm, wide, cuneate at 
the base, acute or long-acuminate at the apex, usually somewhat abruptly so, thin, 
bright green, glabrous above, loosely tomentose beneath along the veins when young, 
glabrate in age, the lateral veins conspicuous, arcuate-ascending; flowers polygamous, 
loosely paniculate, the panicle 9.5 cm. long and as broad, the branches ascending, 
thinly tomentose, the basal bracts linear, 2 to 2.5 cm. long; spikelets sessile, few, 
flowered, 2 to 2.5 mm. in diameter, the rachis lanate; bracts and bractlets ovate- 
orbicular, half as long as the sepals, obtuse or acutish, stramineous, hyaline, glabrous; 
sepals oval, 1.5 to 2 mm. long, obtuse, sparsely lanate at the base, stramineous; stam- 
inodia minute. 
Type in the U. S. National Herbarium, no. 572522, collected near Gémez Farias- 
Tamaulipas, Mexico, altitude 350 meters, April, 1907, by Edward Palmer (no. 291). 
A near relative of Iresine arbuscula Uline & Bray, which is known only from the 
type locality, Volc4n de Tecuamburro, Guatemala, but differing from that species by 
the tomentose branches and leaves and shorter petioles. 
Iresine wrightii Standley, sp. nov. 
Shrub; branches slender, terete, smooth, the young ones and those of the inflo- 
rescence densely canescent; petioles stout, 3 to 7 mm. long; leaf blades obovate- 
oblong or oval-oblong, broadest above the middle, 7 to 9 cm. long, 3 to 4 cm. wide, 
acute at the apex, acute or acuminate at the base, rather thin, sparsely appressed- 
pilose beneath or glabrate; flowers perfect, paniculate, the panicles pyramidal, loosely 
branched, naked, the branches spreading, opposite, the spikelets short, pedunculate or 
sessile; bracts and bractlets one-third as long as the sepals, suborbicular, stramineous, 
sparsely short-villous or glabrate; sepals elliptic-oblong, 2.5 mm. long, acute, brownish- 
fuscous, faintly nerved, short-villous at the apex, pilose at the base, the hairs sordid
