NEW OR NOTEWORTHY BORNEAN PLANTS. 175 
sharply acuminate, base obtuse, the upper surface pale or brownish 
when dry, the lower pale-brownish, both surfaces shining; lateral 
nerves about 12 on each side of the midrib, distinct on the lower 
surface, somewhat curved, obscurely anastomosing, the reticulations 
rather close and distinct on both surfaces; petioles 3 to 7 mm. long. 
Peduncles of the infructescences 1 to 2 qn. long, rather stout, the 
torus woody, up to 1.5 em. in diameter: fruits 5 to 20, ellipsoid to 
oblong-ellipsoid, dark-brown when dry, glabrous, rounded at both 
ends, up to 4 cm. long, 2.5 cm. im diameter; seeds 2-seriate, up to 
8 in each fruit, or in those cases where the fruit is imperfectly djevel- 
oped and globose, only 1

Mrs. Clemens 9670, December, 1915. In thickets along trails and 
in forests at low altitudes. A species well characterized within 
the genus by being, so far as known, entirely glabrous; it is probable 
that the flowers may be more or less pubescent. It is manifestly 
allied to Uvaria lurida Hook. t. & Th., but the seeds are 2-seriate, 
not 1-seriate as in the latter ne 
Artabotrys borneensis sp. nov. 
Frutex scandens, inflorescentiis exceptis glaber vel subglaber ; 
foliis chartaceis, ellipticis vel elliptico-oblongis, pallide olivaceis, 
nitidis, 10-13 cm. longis; utrinque subkaequaliter angustatis, 
basi acutis, apice perspicue obtuseque acuminatis; nervis utrinque 
ee 8, plerumque patulis, perspicuis ; inflorescentiis oppositifoli- 
s, plerumaue 1-floris; pedunculis curvatis, compressis, 1-1.5 cm. 
ica. floribus +4 om. longis; ‘sepalis  ovatis, acuminatis, 
leviter pubescentibus vel vetustioribus glabris, exterlor:bhus oblongo- 
ellipticis, 1.5 cm. latis, obtusis; carpellis circiter 12, glabris, stylis 
crasse Clayatis, obtusis; disco dense ferrugineo-hirsuto. 
A scandent shrub glabrous or nearly so ee for the inflores- 
ences. Branches and branchlets slender, terete, black when dry, 
the ultimate branchlets about 1 mm. in diameter, more or less 
ferruginous-pubescent at their apices. Leaves chartaceous, elliptic 
to elliptic-oblong, pale-olivaceous, shining, 10 to 13 cm. long, 4 to 
6 cm. wide, subequally narrowed to the acute base and to the conspi- 
cuously blunt-acuminate apex, the acumen usually about 1. am. 
long; lateral nerves about 8 on each side of the midrib, mostly 
spreading, arched anastomosing, rather ‘prominent, the TaiGuiltians 
lax and distinct on both surfaces; 4 to 5 mm. long. Inflorescences 
‘on the ultimate branchlets, leaf-opposed, usually only 1-flowered, 
the peduncles stout, strongly curved, compressed, 1 to 1.5 em. long, 
sparingly appressed-ferruginous-pubescent. Flowers 4 to 4.5 em. 
long, their pedicels stout, thickened upward, glabrous or nearly so, 
about 8 mm. long. Sepals coriaceous, ovate, prominently acumi- 
nate, black when dry, glabrous or very slightly pubescent, about 6 
mm. long, 5 mm. wide. Petals thickly coriaceous, all broad, flat, 
sparingly pubescent on both surfaces or ultimately elabrous or
