Vol. 37, pp. 49-54 February 21, 1924 PROCEEDINGS OF THE BIOLOGICAL SOCIETY OF WASHINGTON NINE NEW SPECIES OF PLANTS FROM CENTRAL AMERICA.^ BY PAUL C. STANDLEY. The trees and shrubs described in the present paper were collected mostly by the writer during a visit to Quirigua and Puer-to Barrios, Guatemala, during the early summer of 1922. There are included also descriptions of a new species of Psychotria obtained by Mr. William R. Maxon during a recent visit to Costa Rica, and of two representatives of the genus Coussapoa from Costa Rica. Podocarpus guatemalensis Standi., sp. nov. Branchlets rather slender, the leaves distant; terminal buds small, the outer scales acute, the inner obtuse; leaves thin-coriaceous, lance-linear and elongate, 9.5-15 cm. long, 8-12 mm. wide, long-attenuate to the apex, acute or short-attenuate at base and subsessile, somewhat lustrous, green above, slightly paler beneath, the costa slender, prominent on both surfaces, not sulcate above. Type in the U. S. National Herbarium, no. 1,150,683, collected in wet thicket at Puerto Barrios, Guatemala, at sea level, June, 1922, by Paul C. Standley (no. 25090). Of all the numerous interesting plants collected by the writer on the north coast of Guatemala in 1922, this is doubtless the most interesting, important, and perplexing. The species of Podocarpus are inhabitants of the high mountains, and so far as may be learned from consultation of literature, including the monograph of the genus published in Engler's Pflanzenreich by Pilger in 1903, they are never found in tropical regions at sea level. Three species are known from Central America, all occurring in Costa Rica (one also in Panama) at elevations of 1,700 to 2,400 meters. The Guate-malan plant, consequently, represents a considerable extension of range for the genus northward upon the continent, but it is much more remarkable because of its occurrence in a coastal thicket or swamp. The specimens obtained were taken from a shrub of two meters, which, of 1 Published by permission of the Secretary of the Smithsonian Institution. 5— Proc. Biol. Soc. Wash., Vol. 37, 1924.
