NEW OR NOTEWORTHY BORNEAN PLANTS. 339 
A scandent shrub, the branches frequently emitting rootlets, 
the younger parts, ‘inflorescences, and the lower surface of the 
leaves conspicuously ferruginous- to cupreous-stellate-pubescent. 
Branches terete, 5 to 7 mm. in diameter, the ultimate branchlets 
sometimes compressed or somewhat angular. Leaves opposite, 
orbicular-elliptic to elliptic, coriaceous, 20 to 27 cm. long, 15 to 18 
em. wide, base broadly rounded and sometimes shallowly cordate, 
apex truncate-rounded to acute and conspicuously and abruptly 
apiculate-acuminate, the acumen narrow, up to 7 mm. long, the 
upper surface greenish-olivaceous, shining, glabrous, the lower 
surface ferruginous, minutely and densely stellate-pubescent ; basal 
nerves 7, the inner two pairs reaching the apex of the leaf, some- 
what impressed on the upper surface, very prominent on the lower 
surface, the transverse nerves subparallel, conspicuous; petioles 
stout, densely stellate-pubescent, 2.5 to 3 cm. long. Panicles 
terminal, peduncled, up to 1 m. long, the branches opposite, 
spreading, the lower ones up to 10 cm. in length, all parts ferrugin- 
ous- to cupreous-stellate-pubescent. Flowers numerous, their 
pedicels about 1 cm. long. Calyx, in bud, cylindric, about 15 cm. 
long, 5 mm. in diameter, glabrous or very slightly pubescent, the 
sepals entirely united into a deciduous cone, the cone acute, about 
5 mm. long. Petals 4, glabrous, ovate, acuminate, about 5 mm. 
long. Stamens 8, 4 fertile, the filaments flattened, 2.5 to 5 mm. 
long; fertile anthers oblong-lanceolate, obtuse, 6 to 7 mm. long, 
the connectives not produced, the appendages ovate, membrana- 
ceous, 0.5 mm. long, 1 dorsal and 2 anterior; sterile anthers oblong- 
lanceolate, 2 mm. long, the dorsal appendage oblong-ovate, acute, 
membranaceous, 1 mm. long, the anterior one linear-lanceolate, 
2to3mm. long. Ovary 4-celled, style 4.5 mm. long. Fruits some- 
what urceolate, truncate, glabrous or slightly pubescent, about 1 
em. long. ;

Dalema, up to the present, has been represented by a single known 
species, D. pulchra Korth., of Borneo. The present species differs 
from the type of the genus, not only im its pubescence, the type 
being almost glabrous, but also in its floral characters. In fact, 
the staminal characters are so different in the present species from 
those of the type of the genus that D. pubescens might, with con- 
siderable propriety, be made the type of a distinct genus. In 
D. speciosa the stamens, while dissimilar, are all fertile, the larger 
ones bisetose anteriorly and calcarate posteriorly, the connectives 
of the smaller anthers bituberculate anteriorly and very shortly 
calcarate exteriorly. In the present species, the fertile stamens 
are merely supplied with 2 membranaceous, ovate scales anteriorly, 
and a single similar one exteriorly, while the sterile anthers are" 
supplied dorsally with a very short scale, and ventrally by two 
lateral and one central thin, elongated appendages. In the size 
and shape of its leaves, in its habit, that is, the stems producing
