18 
cm. long, a little shorter than the internodes of the rhachis; leaf- 
lets about 9, the upper, except perhaps the terminal, successively 
larger, imperfectly opposite, on stout petiolules 3 or 4 mm. in 
length, .5-1.5 dm. long, 3-7 cm. broad, oblanceolate, with 
neath downy on the veins; ides terminal, iere much 
branched, short and broad; buds globose-ovoid, obtuse, 2.5—3 
mm. long; calyx nearly plane, 2.5-3 mm. broad, divided mid- 
way; petals purplish-red, 3.5 mm. long; fruit not seen. 
Between Guanai and Tipuani, Apr.-June, 1892 (1454). 
MOSCHOXYLON VIRIDE sp. n. 
Branches stoutish, grayish-red, terete; petioles (the upper) 3- 
5 cm. long, the internodes of the thachix a little shorter ; leaflets 
, the upper successively larger, 6-12 cm. long, 3-5 cm. broad, 
obovate, the cuneate base tapering into a very short petiole, 
obtuse point; entire, membranaceous, bright green, glabrous on 
both sides, venation slender, the primaries about IO or I2 pairs; 
panicles solitary in the axils and terminal, about 1 dm. long ex- 
clusive of the long or short peduncle, pyramidal, lax; flowers not 
seen; fruiting pedicels 3-5 mm. long and like the branches of 
the panicle, slightly cinereous; calyx plane, 3 mm. broad, lobed 
to the middle; fruit (mature ?) ellipsoidal, 8 or 9 mm. long, 6 mm. 
broad, tomentose, yellowish, bluntly triangular, he sides lightly 
grooved, imperfectly 3-celled through the abortion of all but one 
ovule. 
Between Guanai and Tipuani, Apr.-June, 1892 (1370). 
Possibly a Trichilia, though the habit is that of Moschoxylon. 
It is apparently near M. gracile.

gled, the internodes 2.5—3 cm. long; petioles half as long as the 
internodes; blades .7-1 dm. long, 3-4 cm. broad, oblong, the 
base cuneate, the apex abruptly short- and blunt-pointed; dark 
green, coriaceous but not thick, the venation indistinct, strongly 
reticulate, the primaries about 15 pairs, communicating very near 
the margin; pedicels geminate, 4 mm. long; flowering calyx
