MERRILL. 
inflorescentiis axillaribus, solitariis, pedunculatis, multifloris, foliis sub- 
aequilongis; calycis lobis 4 vel 5, setaeeis, brevibus, corollae laciniis 5, 
ellipticis, rotundatis, quam tubus dimidio brevioribus. 
A scandent glabrous shrub. Branches slender, terete, gray. Leaves 
opposite, simple, chartaceous, shining when dry and paler on the under 
surface, oblong-lanceolate to narrowly oblong-ovate, 12 to 15 cm long, 
4 to 6 cm wide, the base acute, the apex narrowed, rounded, obtuse, or 
rarely acute, the base with a pair of slender lateral nerves leaving the 
midrib shortly above the insertion of the petiole, reaching at least to 
the middle of the leaf and anastomosing with the lateral nerves, these 
primary lateral nerves usually 5 or 6 pairs, distant, not prominent, 
scarcely more distinct than are the secondary ones; petioles jointed, 1.5 
cm long. Cymes in the upper axils, solitary, about as long as the leaves, 
many-flowered, the peduncles about 5 cm long, the branches bearing from 
two to five flowers, the bracts and bracteoles minute, setaceous, 1 to 2 
mm long. Pedicels 8 to 10 mm long. Calyx cup-shaped, glabrous, the 
tube 3 to 4 mm long, the teeth 4 or 5, unequal, 1 to 2.5 mm long, linear- 
lanceolate, acuminate, minutely scaberulous. Corolla white, the tube 2 A 
cm long, the lobes 5, elliptic or oblong-elliptic, about 12 mm long, 8 mm 
wide, rounded at the apex, the base broad and minutely biauriculate. 
Anthers 6 to 7 mm long, acuminate.

ALSTON I A R. Br. 
Alstonia paucinervia sp. nov. 
Arbor glabra circiter 15 m alta; foliis chartaceis vel subcoriaceis, 
anguste oblongo-obovatis, usque ad 13 cm longis, basi angustatis, acutis, 
apice breviter latissime aeuminatis vel obtusis, nervis utrinque circiter 15, 
patulis, conspicuis, distantibus; folliculis 20 ad 40 cm longis. 
A glabrous tree about 15 m high. Ultimate branches terete, or the 
tips somewhat 4-angled, smooth, olivaceous. Leaves usually in whorls 
of 4, narrowly oblong-obovate, chartaceous or subcoriaceous, 9 to 13 cm 
long, 3.5 to 5 cm wide, the upper surface smooth and shining, the lower 
surface of about the same color -but dull or very slightly shining, the 
apex very broadly and shortly acuminate or obtuse, gradually narrowed 
from about the middle to the acute base; nerves about 15 on each side 
of the midrib, spreading, distant, prominent, anastomosing close to the 
margin and forming a faint, somewhat looped, submarginal nerve, the 
reticulations lax, rather indistinct; petioles 1 to 1.5 cm long. Flowers 
unknown. Fruiting peduncles from the apical axils, 3 to 4 cm long,
