STANDLEY—TROPICAL AMERICAN PHANEROGAMS. 99 
Type in the U.S. National Herbarium, no. 678516, collected in forests on dry lime- 
stone around Alhajuela, Chagres Valley, Panama, altitude 30 to 100 meters, May, 1911, 
by H. Pittier (no. 3472). ; 
Related to Neea psychotrioides, but that species has much larger leaves with more 
conspicuous veins, broader cymes which are more pubescent, a larger perianth, and 
usually 5 stamens. 
Torrubia dussii Standley, sp. nov, 
Pisonia obtusata Heimerl, Bot. Jahrb. Engler 21: 624. 1896, in part, not P, 
obtusata Jacq. 
Tree of medium size; branches stout, rugose, sordid-grayish, the branchlets stout, 
glabrous except along the nodes, there puberulent, the internodes short; leaves oppo- 
site, unequal, the petioles rather stout, 4 to 8 mm. long, glabrous; leaf blades oval 
or oval-oblong, 8 to 10 cm. long, 4 to 6 cm. wide, rounded or obtuse at the base, ab- 
ruptly acute or cuspidately short-acuminate at the apex, rarely acute, the tip usually 
obtuse, thin, concolorous, lustrous above, dull beneath, glabrous, the margins plane, 
the lateral veins slender, straight, 6 to 12 on each side, the veinlets nearly obsolete, 
laxly and sparsely reticulate; peduncles stout, 3.5 to 4.5 cm. long, glabrous, the inflo- 
rescence cymose, 6 to 8 cm. broad, many-flowered, glabrous, the branches stout, the 
flowers sessile, glomerate, the bractlets oblong or deltoid-oblong, acutish, 1 mm. long 
or shorter, glabrous; staminate perianth funnelform-campanulate, 6 to 7 mm. long, 
glabrous, the limb nearly entire; stamens 6, half longer than the perianth; anthocarp 
ellipsoid, 11 mm. long, 3 mm. in diameter. 
Type in the U. 8. National Herbarium, no. 592420, collected in Guadeloupe, April 
15, 1893, by Pére Duss (no. 2170). 
Related to Torrubia fragrans, but distinct in the large, nearly glabrous staminate 
perianth and the glabrous branches of the inflorescence. 
Torrubia potosina Standley, sp. nov. 
Branches slender, grayish, striolate, the branchlets slender, sparsely ferrugino- 
puberulent when young, the internodes 1.5 to 7 cm. long; leaves opposite, subequal 
or unequal, the petioles slender, 4 to 6 mm. long, sparsely ferrugino-puberulent; leaf 
blades oval or oblong-oval, rarely orbicular-oval, 5 to 10.5, or rarely only 3.5, cm. long, 
2.2 to 5 cm. wide, rounded or acutish at the base, acute or usually cuspidately acute 
or acuminate at the apex, thin, glabrous, concolorous, slightly lustrous on the upper 
surface, the lateral veins prominent, divergent, nearly straight, about 8 on each side, 
laxly anastomosing near the margins, the secondary veins laxly and inconspicuously 
reticulate; pistillate peduncles terminal and axillary, 2.5 to 7.5 cm. long, very slender, 
sparsely puberulent or glabrous, the inflorescence few-flowered, cymose-paniculate, 
1.5 to 3.5 cm. long, the branches opposite or dichotomous, divergent, sparsely ferru- 
gino-puberulent, the flowers solitary or in cymules of 3, sessile or on pedicels 4 mm. 
long or shorter, the bractlets acute, about 0.5 mm. long, puberulent; pistillate perianth 
elliptic-oblong, 2.5 to 3 mm. long, slightly constricted in the throat, sparsely puberu- 
lent, the teeth triangular, acute, erect; anthocarp oval, 7 mm. long and 4.5 mm. in 
diameter; fruit finely striate; seed elliptic-oblong, 6 mm. long and 2.5 to 3 mm. in 
diameter, brown. 
Type in the U. 8. National Herbarium, no. 570197, collected near Rascén, San 
Luis Potosi, Mexico, June, 1905, by Edward Palmer (no. 675). 
The proposed species is of particular interest, since it is the second Torrubia to be 
reported north of Costa Rica. The other Mexican species, 7. linearibracteata, has been 
described only recently, from Yucatan. Torrubia potosina is related, apparently, to 
T. costaricana and T’. linearibracteata, but differs from both in its lax, few-flowered 
inflorescence and broader leaves.
