Philippine form. It is well characterized by its membranaceous, 
slenderly acuminate, few-nerved leaves. 
TABERNAEMONTANA Linnaeus 
TABERNAEMONTANA ECARINATA sp. nov. 
Frutex glaber; foliis charteceis, olivaceis, oblongis ad oblongo- 
ellipticis, 7 ad 14 cm longis, apice late obtuseque acuminatis, 
nervis utrinque 8 ad 10; infructescentiis circiter 6 cm longis, 
haud ramosis, folliculis 2 gerentibus; folliculis 2.5 ad 3 cm longis, 
inaequilateralibus, ecarinatis, apice rostratis; seminibus circiter 
18. 
A glabrous shrub, the branches slender, terete. Leaves char- 
taceous, olivaceous, shining, equal, oblong to oblong-elliptic or 
oblong-lanceolate, 7 to 14 cm long, 3 to 7 cm wide, base often 
slightly inequilateral, somewhat acuminate, apex broadly and 
obtusely acuminate; lateral nerves 8 to 10 on each side of the 
midrib, distinct, anastomosing, the reticulations slender, lax; 
petioles about 5 mm long. Inflorescences apparently very few- 
flowered, the peduncles in fruit up to 6 cm long, simple, each 
bearing a single pair of follicles but usually presenting one or 
two scars of fallen pedicels. Persistent sepals ovate, about 2.5 
mm long. Corolla-tube about 12 mm long, the lobes spreading, 
narrow, about 1.5 cm long. Follicles yellow, 2.5 to 3 cm long, 
1.5 to 2 cm wide, inequilateral, smooth, not at all keeled, some- 
what compressed, one side nearly straight, the other semi- 
circular, apex rather prominently rostrate. Seeds up to 18 in 
each follicle, irregular, 7 to 8 mm long.

This species is strongly characterized by its rostrate, rather 
many-seeded follicles, which are not at all keeled. In vegetative 
characters it resembles some forms of Tabernaemontana panda- 
caqui Poir. but differs entirely in its fruit characters.
