4 BRITTON: STUDIES OF WEsT INDIAN PLANTS—XII 
70. UNDESCRIBED SPECIES FROM TRINIDAD 
Anthurium aripoense N. E. Brown, sp. nov. 
Glabrous in all parts. Petioles about 75 cm. long and (when 
dried) 4 m hick, sheathing for about 7 at their base, 
apparently more or less flattened above with obtuse edges, 
ounded on the back; blades about 34 cm. long, a 
across the basal lobes and 18% cm. broad at the constriction, 
cordate, with the basal lobes slightly constricted into the front 
lobe at about 11 cm. above the insertion of the petiole; basal sinus 
about 4 cm. deep, broadly open, rounded; basal lobes semi- 
orbicular; ton lobe ovate, abruptly acute, apiculate; both 
surfaces green; basal nerves 4 on each side of the midrib, the 3 
outer united and denuded at the sinus for about 25 mm., much 
curved and all excurrent at the margin below the middle of the 
leaf; the inner one free, ascending and excurrent at the apex, 
running subparallel with the margin at about 12-15 mm. 
from it; primary lateral veins about 7 on each side of the midrib, 
with others similar but less prominent between them, widely 
spreading, subparallel, nearly straight. Peduncle about 57 cm. 
long, 4mm. thick (dried), apparently terete. Spathe 11 cm. long,- 
road, strap-shaped or broadly linear, with a subulate 
point about 25 mm. long. Spadix 15 cm. - long, 5 mm. ic at 
t 
e base, much longer than A e spathe, on a stipe 5 mm. Jong, 
pesos vices or dark purple F hs dtaceaaee shaped, 
4 m n their longer and 3 mm. in their shorter diameter.

The venation of the leaf of this species is on the same plan 
as that of A. Guildingii Schott, but in outline the slight constric- 
tion above the basal lobes brings it nearer to A. panduraeforme 
Schott. 
Piper maravalanum Trelease, sp. nov. 
Stem nodose, glabrous; leaves ovate or elliptic-ovate, acumin- 
ate, equilaterally rounded at base, rather large (6-9 & 15-17 
not wi 
yet comparatively short and thick (2 X 15 mm.), mucronate; 
peduncle very short (scarce 5 mm.); bracts lunulate-subpeltate, 
rusty-ciliate; flowers sessile, periect; stigmas 3, minute, sessile. 
Maraval, December 30, 1914, (Broadway 7829, the TYPE 
in the New York Botanical Garden) 
Scarcely to be placed anywhere except in close connection 
with P. Schackit and P. ovatum; but pubescent benrath on the 
veins.
