NEW OR NOTEWORTHY PLANTS FROM COLOMBIA AND 
CENTRAL AMERICA. 
By Henry Pirrier. 
The present paper includes descriptions of a few plants from collec- 
tions made mainly in the course of my explorations in Costa Rica 
from 1887 to 1903, and of others obtained more recently in Guatemala 
and Colombia in connection with investigations conducted on behalf 
of the United States Department of Agriculture. 
The two species from Colombia, Roupala ferruginea and Phyllan- 
thus salviaefolius, are old, but have remained little known; addi- 
tional specimens permit several interesting facts to be added to the 
original descriptions by Kunth. The discovery in Costa Rica of two 
new species of Phyllonoma bridges a gap in the geographical distri- 
bution of a genus which has hitherto appeared widely interrupted, as 
its previously known members came from Peru and Colombia on the one 
side and from central Mexico on the other. The three Costa Rican 
species of Carpotroche show the extension toward the west and north 
of a genus thus far considered almost exclusively Brazilian. The 
remaining species, besides being new, have several interesting features 
which are noted in connection with the descriptions. JI am greatly 
indebted to Dr. Th. Loesener, of the Berlin Royal Herbarium, for 
his help in the identification of Myginda eucymosa. 
Roupala ferruginea H. B. K. Nov. Gen. & Sp. 2: 153. pl. 120. 1817. 
A small tree, with alternate limbs, the younger branchlets, petioles, main and 
secondary veins, peduncles and pedicels ferruginose-tomentose. 
Leaves alternate, petiolate; petioles rather thick, 1 cm. long; leaf-blade firm, 
rounded at base, ovate, more or less acute, pale green and subglabrous above, brownish 
white and delicately reticulate-venose beneath. 
Racemes axillary, pedicellate, the pedicels 3 mm. long, adnate at base. Perianth 
7 to8 mm. long, glabrous outside, longitudinally striate. Stamens glabrous; filaments 
5 mm. long, flattened, adhering to sepals; anthers ovate-elliptic, about 2 mm. long; 
end of connective rounded, scarcely surpassing the anthers. Pollen grains about 
0.027 mm. in diameter, tetrahedral with a round nucleus. Glandular appendages 
at base of pistil glabrous, square at tip; pistil 7 mm. long; ovary ovate, hairy; 
style claviform. 
CotomsB1A: Loma Gorda near Jambalé, Department of Cauca, at an altitude of 
2.400 meters, H Pittier, no. 1451, flowers February 5, 1906 (U. S. National Herba- 
rium no. 531649).
