faces, subequally narrowed to the acuminate base and apex, the 
apical acumen obtuse, stout, about 1 cm long; primary lateral 
nerves about 16 on each side of the midrib, spreading, distinct, 
anastomosing, the reticulations distinct. Panicles axillary, 
solitary, 3 to 4 cm long, peduncled, narrowly pyramidal, few- 
flowered, the lower branches 1 cm long or less. Young flowers 
about 3 mm long, the petals 4, oblong, obtuse, glandular. Sepals, 
ovate, obtuse, 1 mm long. Staminodes 4, about 1 mm long. 
Ovary glabrous, deeply 4-lobed, the immature carpels brown, 
about 3.5 mm long.

The alliance of this species is apparently with Evodia ternata (Blanco) 
Merr., from which it is readily distinguished by its thicker leaflets which 
vary in number from 1 to 3; its short, few-flowered inflorescences; and 
in being entirely glabrous in all parts.

Arbor glabra, circiter 15 m alta, ramis crassis, rugosis, cicat- 
ricibus perspicuis instructis; foliis crasse coriaceis, obovatis, in 
siccitate olivaceis vel olivaceo-brunneis, usque ad 11 cm longis, 
apice latissime rotundatis, basi cuneatis, obscure punctatis, ner- 
vis utrinque circiter 8; inflorescentiis usque ad 15 cm longis, 
longe pedunculatis ; floribus circiter 5 mm diametro, petalis 
latissime ovatis, acutis vel obscure acuminatis, circiter 2.5 mm 
longis latisque. 
A glabrous tree about 15 m high. Branches stout, rugose, 
about 6 mm in diameter, grayish or grayish-brown, marked with 
numerous large petiolar scars. Leaves thickly coriaceous, obo- 
vate, 6 to 11 cm long, 4 to 7 cm wide, shining, olivaceous or 
brownish-olivaceous when dry, the lower surface often paler 
than the upper, the apex very broadly rounded, the base cuneate, 
the upper surface obscurely pitted, the lower obscurely glan- 
dular-punctate ; lateral nerves about 8 on each side of the midrib, 
rather conspicuous, anastomosing, the reticulations lax ; petioles 
1 to 2 cm long. Inflorescences from the upper axils and sub- 
terminal, long-peduncled, up to 15 cm long, the branches few, 
the lower primary ones up to 6 cm in length. Flowers fragrant, 
yellowish-green, dark-brown when dry, about 5 mm in diameter, 
somewhat crowded on the ultimate branchlets, shortly pedicelled. 
Calyx somewhat turbinate, 2.5 to 3 mm in diameter, shallowly 
toothed. Petals broadly ovate, about 2.5 mm long and wide, 
acute or somewhat acuminate. Filaments about 3 mm long.
