the midrib about 16, the veins connecting the lower vein with the margin 
■as well as those connecting succeeding pairs of veins very distinct, nearly 
straight or more or less curved, with in addition one or two veins similar 
to the first branch of the basal vein running from the insertion of the 
petiole a short distance below the basal vein itself ; veins of both surfaces 
and sometimes the lamina of the lower surface more or less pubescent, 
the lower surface of the midrib densely pubescent; stipules triangular- 
lanceolate, very acute, 15 mm long.

4. Laportea crassifolia sp. nov. 
Inflorescentiis pistilliferis longis, pubescentibus, floribus sessillibus in 
receptaculis flabellatis admodum congestis, perianthio 4-partito, lobis 
interioribus longioribus angustioribusque : foliis magnis, coriaceis, ovatis 
vel suborbicularibus, utrinque dense pubescentibus, basi cordalis, mar- 
gine dentatis. 
Pistillate inflorescences 12 to 30 cm long, the peduncle and rachises 
stout, densely hoary-pubescent, widely branched : flowers sessile, 12 to 15 
in number, in flabellate receptacles about 2 mm in width, with pedicels 1 
to 2 mm long, passing gradually into the receptacle itself; bracteoles 
1.5 mm long, oblong, aeutely acuminate : perianth 4-parted, the two 
inner 0.5 mm long, triangular-lanceolate, acute, the outer shorter, ovate, 
acutely acuminate, all sparingly pubescent on the outer surface, ovary 
ovoid-compressed, less than 1 mm long, ventricose, hardly oblique, passing 
gradually into the subulate pubescent stigma, which is about 2 mm long 
and curved at the apex : fruiting receptacles white, varying in size with 
development, attaining a width of at least 12 mm, the achene orbicular- 
ovate, compressed, 2.5 mm long, its surface more or less tuberculate: 
immature staminate inflorescences 8 mm long, densely pubescent, the 
flowers crowded in glomerules : perianth-segments 4, ovate, cucullate, 1 
mm long. 
A tree about 6 m high, its stem 15 cm in diameter; leaves with stout 
densely pubescent' petioles 6 to 12 cm long, the coriaceous lamina 2.0 to 30 
cm long, 13 to 30 cm wide, the base cordate, -the margins except in the 
basal sinus forming more or less shallow but very conspicuous acute or 
obtuse teeth, the sinuses rounded or truncate, apices shortly acuminate; 
both surfaces, especially the under, densely covered with grayish or yel- 
lowish pubescence; lateral veins on each side of the midrib 12 to 15, 
arched-ascending, the veins connecting these fairly conspicuous; stipules 
elliptic, membranaceous, 25 mm long, glabrous except the midvein.
