TWO PANAMANIAN SPECIES OF PROTIUM. 
Protium ternatum Pittier, sp. nov. 
A small tree, with smooth gray bark. 
Leaves membranous, glabrous, ternate, 15 to 30 cm. long, the petioles stout, 
subterete, 2.5 to 3.5 cm. long; leaflets large, petiolulate, the petiolules canali- 
culate, thickened at the apex, those of the lateral ones 0.7 to 1.5 em. long, that of 
the terminal one 2.5 to 4 em. long, the blades ovate-elliptic, acute at the base, 
obtusely short-acuminate at the apex, 10 to 22 em. long, 4 to 8 cm. broad, the 
costa prominent on both sides, the main lateral veins (about 10) and the 
minor venation prominulous and reticulate. 
Inflorescences up to 15 cm. long, axillary, ramified from the base, few- 
flowered, glabrous, the branches slender and angular; flowers pedicellate, 
greenish yellow, the pedicels 3 to 5 mm. long; calyx shallowly 4-lobulate, 
glabrous; petals 4, broadly ovate, obtuse or sometimes acute at the apex, 2.5 
mm. long, 1.6 to 2.2 mm. broad, glabrous or sometimes minutely pubescent to- 
ward the tip; stamens 8, the filaments broader at the base, about 2 mm. long, 
the anthers small, ovoid; disk thick, annular, sulcate, glabrous, covering about 
half the ovary; ovary subglobose, glabrous, 4 or 5-celled, the style very short, 
the stigma 4 or 5-lobed. 
Drupe oblique-ovoid, acute, apiculate, about 1 cm. long, glabrous, orange-red. 
Type in the U. 8S. National Herbarium, no. 679294, collected along Rio Faté 
(Nombre de Dios), Province of Col6én, Panama, in flower, August 16, 1911, by 
H. Pittier (no. 4190). A second collection, same locality and date, is Pittier 
4191. 
This species seems to be nearly related to Protium guiancse Marchal, but 
it differs in the peculiar structure of the petiolules, the size of the leaflets, 
the length of the pedicels, and the shape of the petals. Besides, the leaves 
have always three leaflets or fewer, while in P. guianense they are sometimes 
bijugate. 
Protium inconforme Pittier, sp. nov. 
A small tree, the bark of the branchlets smooth and light gray. 
Leaves glabrous, 2 or 3-foliolate, up to 12 em. long, the petioles rather slender, 
at first distinctly canaliculate above, 1 to 1.5 em. long; leaflets very variable in 
size, the petiolules 0.3 to 1 em. long, canaliculate, the blades narrowly ellip- 
tie to ovate, obtuse at the base, obtuse or obtusely subacuminate at the apex, 
4 to 10 cm. long, 1.5 to 4 cm. broad, the costa prominent on both faces, the main 
nerves (about 12) and the reticulate veins and veinlets more or less prominent 
beneath, 
Inflorescences short, in solitary axillary few-flowerel racemes, up to 2.5 cm. 
long, the rachis sparsely puberulous; flowers pediceled, pale yellow, the 
pedicels 2 to 3 mm, long, puberulous, provided at the base with a brown 
scarious ciliate deciduous bractlet; calyx 4 or 5-lobed, the lobes broad, short, 
obtuse; petals 4 or 5, 2.5 mm. long, 1 to 1.5 mm. broad, subacute, glabrous or 
minutely puberulous; stamens 8 or 10, the filaments 0.7 to 1 mm. long, the 
anthers small, ovoid; ovary subovoid or globose, surrounded by the glabrous 
disk only at the base, sparsely hairy, about 0.8 mm. long, the style much 
shorter, 4 or 5-lobulate. 
Fruit ovoid-oblong, stipitate, apiculate, 2-seeded, glabrous, about 2 cm. long: 
seeds somewhat 3-carinate, 1.1 em. long.
