being grown from seeds brought from the forests of the Department of 
La Libertad, where it is native. I saw many of the trees planted along the . 
roads in the neighborhood of Sonsonate, and a fine large one in a finca at 
Tonacatepeque. 
Exandra Standl., gen. nov. 
Shrubs or trees. Leaves opposite, petiolate, the blades large, thin. Stip- 
ules interpetiolar, caducous. Inflorescence terminal, the flowers small, 
numerous, in paniculate cymes, sessile or short-pedicellate, bracteate and 
bracteolate; hypanthium clavate, somewhat obcompressed; calyx short, 
persistent, irregularly 5 or 6-lobate, the lobes triangular, obtuse or acute, 
thin, about equaling the tube; corolla shortly and broadly funnelform, glab- 
rous within and without, open in bud, the tube broadly obconic, the 5 or 6 
lobes nearly obsolete, broadly rounded, recurved in anthesis. Stamens 
5 or 6, inserted at the middle of the corolla tube, alternate with the lobes, 
the filaments stout, long-exserted, pubescent below; anthers oblong, obtuse, 
dorsifixed near the base, dehiscent by lateral slits. Disk annular, shallowly 
lobate. Ovary 2-celled; style stout, nearly equaling the stamens, glabrous, 
‘deeply bilobate, the lobes oblong, obtuse; ovules numerous. 
Type species, Hxandra rhodoclada Standl. 
Exandra rhodoclada Standl., sp. nov. 
A shrub or tree, the young branchlets minutely puberulent; stipules about 
2 cm. long, attenuate, puberulent; petioles slender, 2.5-4 cm. long, subterete, 
minutely puberulent; leaf blades rounded-ovate or rounded-oval, broadest 
near the middle, 20-80 cm. long, 16-25 em. wide, short-acute or acuminate 
at apex, often somewhat abruptly so, slightly narrowed below and at base 
shallowly or deeply cordate, thin, glabrous except beneath upon the nerves, 
there minutely puberulent, the costa slender and salient beneath, the lateral 
nerves about 11 pairs; panicles short-pedunculate, dense, about 9 cm. long, 
pyramidal, the rachises fulvous-puberulent; bracts and bractlets lanceolate 
to triangular, small and deciduous; flowers mostly sessile; hypanthium 
puberulent, 3 mm. long; corolla 4-5 mm. long, 3.5-4 mm. broad; filaments 
5-6 mm. long, the anthers 2 mm. long. 
Type in the U. 8. National Herbarium, no. 229232, collected between 
La Venta and Niltepec, Oaxaca, Mexico, altitude 60 meters, July 14, 1895, 
by E. W. Nelson (no. 2796). 
Additional specimens examined:

in the Sierra de Apaneca, Departamento de Ahuachapdn, January, 1922,

The Mexican specimen is said to have been taken from a shrub or tree 
of 2.5 to 4.5 meters, with brownish and green flowers. Both the Salvadorean 
specimens are sterile but there is little doubt that they represent the same 
species. They were taken from trees, for which the vernacular names were 
given as brasil and limpia-dientes. Dr. Calderén reports that the tree 
yields lumber of good quality. 
The systematic position of the proposed genus is doubtful because of the 
lack of fruit, but the writer has little hesitation in making the tree the type
