cm. long and 2 cm. broad. Costa subimpressed above, salient beneath, the fine 
primary veins forming with it an angle of about 40°. 
Flowers entirely glabrous, in clusters of 2 to 8 on the foliar nodes. Pedicels 3 to 
6.5 mm. long. Sepals 5, ovate, 2 to 2.5 mm. long, persistent. Corolla white, about 
4.2 mm. long, deeply cleft; exterior lobes 5, 
oblong, with smooth margin; interior lobes 10, 
lanceolate, acute or bicuspidate, little shorter 
than the exterior ones, each pair inserted in the 
sinuses between these. Stamens 5, inserted in 
the middle of the tube; anthers ovate-lanceolate, 
dorsifix, exserted. Staminodes nearly as long 
as the exterior lobes of the corolla, ovate, 
rounded at tip, with a slightly denticulate 
margin. Pistil 3.5 mm. long; ovary smooth, 
globose, 5-celled, glabrous but with a crown of 
stiff hairs at the base; style slender, glabrous, 
persistent, ending in a minute papillose stigma.

SYMPLOCACEAE. 
A NEW SPECIES OF SYMPLOCOS. 
Symplocos chiriquensis Pittier, sp. nov. Fiaures 94, 95, 
Section Eusymplocos, subsection Ciponimastrum. A tree up to 30 meters high, 
Trunk straight, 50 cm. in diameter or less; bark grayish. Floriferous branchlets with 
purplish green, quite smooth, bark. 
Leaves only on new growth at ends of branchlets, alter- 
nate, petiolate, entirely glabrous (though covered with 
gray hair in young buds). Petioles 7 to 10 mm. long, 
canaliculate, subdecurrent on the branchlets. Blades 
membranous, 5 to 10 cm. long, 2.5 to 3.5 cm. broad, ellip- 
tic, cuneate at base, more or 
less rounded-acuminate at tip, 
almost shiny above, a shade 
paler and with prominent ve- 
nation beneath; margin cre- 
nate, subrevolute.

, times as long as the petinles; 
rachis minutely hairy. Flowers odorous. Pedicels 0 to 1.5 mm. long. Calyx cam- 
panulate, 4 or 5-lobate, surrounded at base by 3 to 5 very caducous, deltoid, apicu- 
late bractlets, about 1 mm. long and pilose-ciliate on the margin; calyx lobes 
broadly rounded, ciliate on the margin. Corolla pink, 10 mm. long, the tube equal 
in length to the calyx lobes, the 5 petals obovate-oblong, 4 to 5 mm. broad, more or 
less ciliate toward the base and apparently not reflexed. Stamens numerous (about 
35), 3-seriate, free at the upper part, included, but the longest not much shorter than 
the corolla; free part of the filaments flattened, finely apiculate at the tip; anthers
