STIGMATOPHYLLON COLORATUM Sp. n. 
Stems strongly twining, slender, slightly channeled, pubescent, 
some of the hairs retrorse; leaves of the pair nearly equal; peti- 
oles 2.5—8 cm. long, rather stout, pubescent, the blackish broadly 
spheroidal closely sessile glands near the summit; blade 5-15 
cm. long, 4-12 cm. broad, regularly cordate-ovate, with nearly 
closed sinus, with very abrupt slight acute apical prolongation, and 
obscurely denticulate margin, the veins with short aristiform pro- 
longations ; glabrous both sides, bright green above, rich purple 
underneath, except for the green margins; primaries about 8 pairs, 
slender, rather crooked, prominent underneath, connected by the 
secondaries and forked-reticulate near the margin; peduncles axil- 
lary, 4-8 cm. long, slender, pubescent, 2-4-angled, compressed at 
the summit, about 20-flowered, bearing among the pedicels sev- 
eral glands like those of the petioles; pedicels very unequal, many 
times shorter than the peduncles; bud obovoid, with a broad sum- 
mit; calyx hemispherical, 5 mm. broad, the sepals broadly ovate 
with rounded summit, the blackish glands oblong, appressed, two- 
thirds the length of the calyx, petals 12-15 mm. long; stigmatic 
appendage conspicuous, green, puberulent; samaras (in my speci- 
men) 1—3, 2.5-3.5 cm. long, about 13 mm. broad at the base, the 
wing abruptly contracted at the back, near the base, to 1 cm., the 
apex blunt or rounded, the ventral margin irregularly sinuate 
above, the surface sparsely gray-pilose, finely very many nerved.

Bannisteria sp., near B. argentea (H. B. K.) Spreng., but in bud 
only. Between Guanai and Tipuani, Apr.-June, 1892 (1365). 
Bannisteria, apparently an undescribed species intermediate be- 
tween JB. Martiana and B. lucida, but fruit is lacking.

BorLivIANA. n. var. 
e younger portions puberulent or canescent; branchlets 
reddish, stout, the internodes 5-7 cm. long; petioles 1—1.5 cm. 
long, stout; blades 1-1.5 dm. long, 5-8 cm. broad, oval-obovate, 
the base subcordate and mostly inequilateral, the apex with a very 
short blunt point, revolute, thin but rigid, somewhat shining on 
both sides, sparsely pubescent on the veins beneath, the primaries 
5 or 6 pairs, strongly falcate-ascending, connected by the numer- 
ous slender crooked secondaries, the reticulation elongated and 
rather coarse; panicles axillary and terminal, sessile or short-pe-
