Abundant in the Gull}-. The flowers are rather white streaked
with violet and with a yellow blotch in the tube, than purplish
streaked with white as originally described. Endemic.

132. DiDYMOCARPUS (SaLICIN^E) FILICIFOLIA, H. Sp.
Stem woody, 3— 4 inches long. Leaves crowded at the
oblong, linear, acuminate, base more or less narrowed,
decurrent and obtuse on the petiole, margins bluntly closely
serrate, above dark green, beneath whitish, glabrous, midrib
and petiole transversely rugose, nerves about 17 pairs, 3^-5^
inches long, \ inch wide or little less ; petiole ^ iuch long.
Peduncles *
red, scurfy, slender, 1^-2 inches long, 2-4
flowered. Bracts linear, acuminate, ^ inch long. Calyx-lobes
narrow, linear acute, as long. Corolla short, campanulate,
curved ; lobes ovate, acute, i inch long, white. Capsule
linear, cylindric, acuminate, half an inch long.

Padang stream, local and nearly
Closely allied to D. salicina, Ridl., of the Tahan River, but
differing in its leaf-base which is decurrent on the petiole
above, ending in a rounded point, the short petiole, more
parallel-sided leaves, and larger white flowers. The wrinkled
midrib is very curious.
133. [DiDYMOCARPUS ERIC^FLORA, n. Sp.
Stem over a foot tall, ^ inch through, woody, pale glabrous
below, red-brown above when dry. Leaves elongatelanceolate,
apex long, acuminate, base narrowed gradually,
somewhat inequilateral, glabrous, nerves 16-18 pairs, very
inconspicuous, midrib elevated, transverseh- rugose below,
channelled above, 6 inches long, i inch wide ; petiole \ inch.
The leaves are in slightly unequal-sized opposite pairs. Bracts
2, linear, glabrous. Peduncles ^ inch long, adnate to the
petioles. Pedicels erect, slender, ^ inch long, scurfy, pubescent.
Flowers in pairs, white. Sepals 5, linear, obtuse, blimt, green,
^ inch long, very narrow, spreading. Corolla ^ inch long,
thick, tubular, slightly gibbous, below pubescent, white ; lobes
very short, -^j^ inch long, ovate-obtuse, subequal, violet, glabrous
within. Stamens 2, very short, less than half the
length of the tube; filaments linear, straight; anthers rather
large, cordate, obtuse. Style longer, fairly stout, pubescent
ovary angled, tapering slightly upwards. Stigma orbicular.
Capsule I inch long, cylindric, acuminate at the tip, slightly
upcurved, glabrous.
Wray's Camp, Tahan, not common.
The only plant at all allied to this is D. lilacina, Ridl.,
which is common on the Tahan River. It is allied in the
connature of the axillary peduncle of the inflorescence to
the petiole, in the groove of which it seems to be imbedded.
The short broad corolla-tube (somewhat of the shape of a
heath flower), the short stamens (of which, however, the
anthers are not connivent as in Parabcea, but are free and ovate,
