140 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
very thin, bright green, glabrous on the upper surface, sparsely short-villous beneath, 
ciliolate, very faintly veined, the lateral veins 3 or 4 pairs; peduncles terminating 
short lateral branches, 2 to 4-flowered, sometimes dichotomous or often reduced to a 
single secund branch, the flowers in the axils of the branches sessile or subsessile, the 
others on slender pedicels 10 mm. long or less, the peduncles slender, 7 to 15 mm. 
long, sparsely villous; calyx 3 to 3.5 mm, long, glabrous or nearly so, the lobes broadly 
triangular, less than half ag long as the tube; corolla about 22 mm. long, slightly broad- 
ened upward, very sparsely villous outside, especially about the lobes, these oval- 
ovate, obtuse, 1.5 mm. long; anthers equaling or usually slightly exceeding the corolla 
lobes; fruit not seen. 
Type in the U. 8. National Herbarium, no, 678513, collected in forests on dry 
limestone, around Alhajuela, Chagres Valley, Province of Panama, Panama, at an 
altitude of 30 to 100 meters, May 12 to 15, 1911, by H. Pittier (no. 3469). 
Distanct from all other species by the much reduced inflorescence and small leaves, 
It is related, possibly, to H. chrysantha Swartz, but has fewer, differently arranged 
flowers, shorter petioles, and more pubescent, thinner, verticillate leaves. 
Hoffmannia pittieri Standley, sp. nov. 
Stems herbaceous, terete, glabrous; stipules triangular, acutish, 3 mm. long; petioles 
slender, glabrous, 2 to 3 cm. long; leaf blades oblong-obovate to oval-oblong, 12 to 24 
cm. long, 6 to 9 cm. wide, abruptly acuminate, the tips obtuse, attenuate to the base, 
glabrous, dull green above, paler beneath, prominently veined; cymes on peduncles 
2 to 3 mm. long, the secondary branches 10 to 18 mm. long, angled, puberulent, the 
whole inflorescence loose and open; bracts oblong-linear, acute, deciduous; pedicels 
(in fruit) about 4 mm, long; open flowers not seen, the corolla said to be yellow; calyx 
and ovary together (in bud) about 3 mm. long, sparingly puberulent, the calyx lobes 
ovate, obtuse or acutish; fruit cylindric-campanulate, 5 mm. long, glabrous, costate; 
seeds numerous, brown, favose. 
Type in the U. 8. National Herbarium, no. 677642, collected in the humid forest 
between Alto de las Palmas and top of Cerro de la Horqueta, Chiriqui, Panama, 
aliitude 2,100 to 2,250 meters, March 18, 1911, by H. Pittier (no. 3247). 
Distinguished from the other Costa Rican and Panamanian species by its open inflo- 
rescence and large, broad leaves. 
Palicourea chiriquina Standley, sp. nov. 
A shrub 2 to 3 meters high, glabrous throughout; branches rather stout, yellowish 
green, obtusely quadrangular; stipules united to form a sheath 2 to 3 mm. long, each 
stipule bilobate, the lobes linear, acute, slightly shorter than the sheath; petioles 
stout, 6 to 15 mm. long; leaf blades elliptic-oval or elliptic-oblong, 5 to 10.5 cm. long, 
2 to 5 cm. wide, acute or acuminate, often abruptly so, obtuse to broadly cuneate at 
the base, subcoriaceous, yellowish green, somewhat lustrous on the upper surface, the 
veins conspicuous on both surfaces, diverging nearly at right angles, the lateral ones 
about 15 on each side, parallel; inflorescence thyrsoid-paniculate, on peduncles 2 to 4 
cm. long, the panicles 4 to 5 cm, long and 2.5 to 4.5 em. wide, loosely branched, the 
branches spreading, green; bracts oblong or narrowly ovate, 1.5 to 3 mm. long; pedi- 
cels slender, 2 to 4 mm. long; calyx scarcely 1 mm. long, about equaling the ovary, 
the lobes of the limb rounded-ovate, obtuse; corolla 6 mm. long, stout, sulphur-yellow, 
glabrous outside, long-bearded within at about the middle, the lobes of the limb very 
short, rounded-ovate; fruit not seen. 
Type in the U. S. National Herbarium, no. 677607, collected in the humid forest 
of Cuesta de las Palmas, southern slope of Cerro de la Horqueta, Chiriquf, Panama, 
at an altitude of 1,700 to 2,100 meters, March 17 to 19, 1911, by TH. Pittier (no. 3211), 
Additional material is mounted on sheet 677606. 
Related to Palicourea mexicana, but sufficiently distinguished by the short yellow 
corolla, spreading green branches of the inflorescence, and smaller leaves.
