’ cordate. Ovary silky-hairy, 4 or 5-celled, each cell 2-ovulate; style slender, about 
7mm. long, slightly hairy at the base, smooth above; stigma capitellate, obscurely 
multilobulate and papillose. 
Fruits not known. 
Type in the U.S. National Herbarium, no. 677388, collected in forest along the 
Caldera River near El Boquete, Chiriqui, Panama, at an altitude of about 1,100 meters, 
flowers, March 4, 1911, by H. Pittier (No. 2994). 
Very likely the same species which was collected in Veraguas by Seemann and cited 
in his Flora of Panama! as Symplocos martinicensis Jacq. No mention of this locality 
is made in Hemsley’s Biologia Centrali-Americana and Brand, the monographer of 
the family Symplocaceae in the Pflanzenreich, does not seem to have seen Seemann’s 
specimens. Our tree differs from S. martinicensis by its smaller leaves, its peculiar 
ciliate-apiculate bractlets, the more broadly rounded calyx lobes, and the rather 
dense silky-hairy pubescence of the ovary. 
VERBENACEAE. 
NEW SPECIES OF CITHAREXYLUM AND VITEX AND AN OLD ONE 
OF VITEX. 
Citharexylum macranthum Pittier, sp. nov. 
A forest tree, 25 to 30 meters high, the trunk up to 50 cm. in diameter at the base. 
Trunk straight, covered with a reddish rugose bark. Crown elongate; limbs slightly 
ascending. Terminal branchlets 4 or 6-angled, thick, glabrous, more or less fistulose, 
Leaves thin, petiolate, entirely glabrous, usually alternate but often ternate at the 
end of the younger, floriferous shoots. Petioles 1.5 to 3 cm. long, more or less broadly 
suleate. Leaf blades ovate to elliptic, 10 to 24 cm. long, 6 to 9 cm. broad, more or less 
rounded-attenuate and provided with two large glands at the base, subacute or rounded 
at tip, smooth above, finely reticulate between the salient veins beneath; margin 
entire. / 
Inflorescence subterminal with the racemes axillary, usually ternate, on the 2 or 3 
upper nodes of the branchlets. Rachis slender, glabrous or minutely hirsute, 12 to 
25cm. long. Flowers distinctly zygomorphous and large for the genus (about 17 mm. 
long). Pedicels very short (not over 0.5 mm. Jong), minutely hirtellous. Calyx 5mm, 
long, salver-shaped, irregularly 5-toothed, subglabrous or finely pubescent. Corolla 
15.5 to 17 mm. long, white, glabrous; tube broad, cylindrical, slightly arcuate, about 
11 mm. long; lobes 5, well developed, the median one irregularly rounded-acuminate 
with a narrow claw, the lateral ones elongate, conchiform and obtusely pointed at tip. 
Stamens included, inserted below the middle of the tube, entirely glabrous; filaments 
slender; anthers elliptic, emarginate at base, rounded at tip. Pistil entirely glabroue, 
4mm. long; ovary ovoid, 4-celled, each cell 1-ovulate; style 1 to 1.5 mm. long; stigma 
capitellate, subbilobate, papillose on the surface. 
Fruit not known. 
Type in U. 8S. National Herbarium, nos. 678974 and 679301, collected along Rfo 
Faté, above Nombre de Dios, Province of Colén, Panama, in high forest, flowers, 
July 8 and August 16, 1911, by H. Pittier (nos. 3897 and 4199). 
This tree departs from all hitherto described species of the genus by the ternate 
leaves and racemes of the floral branchlets, the unusually large corollas, the stamens 
inserted well in the lower half of the corolla tube, and the very short pistil. It shares 
with C. macradenium Greenm., the peculiarity of having very large glands at the 
base of the leaf blade. The core of the trunk is of a dirty yellow color. The wood is 
hard, but tough, and little used, The tree is called ‘‘iguanero” by the natives.
