the branches rufous-villosulous, the flowers subsessile or the pedicels so:me- 
times 5 mm. long, the bracts minute; calyx rufous-villous or villosulous, the 
tube obovoid, 2.5 to 3 mm. long, the lobes triangular or narrowly triangular, 
1 to 15 mm. long, obtuse; corolla 8 to 9 mm. long, white, tinged with rose, 
sparsely villous or villosulous, the lobes oblong, obtuse, slightly shorter than 
the tube; fruit oval, about 6 mm. long, villosulous; seeds about 1 mm. long, 
brown, dull, coarsely reticulate. 
Type in the U.’S. National Herbarium, no. 392077, collected in forests of Santa 
Rosa Copey, Costa Rica, altitude 1,800 to 2,000 meters, April, 1898, by A. 
Tonduz (no. 12230). Tonduz’s numbers 11671 and 11909, from the same 
locality, collected in February, 1898, represent the same species. 
Hoffmannia cuneatissima Robinson, described from Morelos, Mexico, is a 
similar plant, but in it the calyx lobes are minute and the lobes of the corolla 
longer than the corolla tube. 
Hoffmannia confertiflora Standl., sp. nov. 
Branches slender, obtusely quadrangular, glabrous, the internodes elongate; 
stipules caducous; leaves opposite, the petioles 5 to 10 mm. long, glabrate, the 
blades elliptic or oblong-elliptic, 6 to 11.5 em. long, 2.5 to 4 em. wide, acuminate 
or long-attenuate at the base, acuminate at the apex, membranaceous, “deep 
green above, copiously ferrugino-villous, paler beneath, villosulous along the 
veins, the lateral veins prominent, about 11 on each side, arcuate-divaricate; 
cymes sessile, few-flowered, dense, the flowers sessile or short-pedicellate, 
4-pafted ; calyx 2 to 2.5 mm. long, glabrous, the lobes minute, broadly deltoid; 
corolla 9 mm. long, glabrous, the lobes lance-oblong, acute, equaling the tube; 
anthers 3 mm. long. 
Type in the U. S. National Herbarium, no. 888491, collected at San Miguel 
Uspantin, Quiché, Guatemala, altitude 2,100 meters, April, 1892, by Heyde 
and Lux (J. D. Smith, no. 3169). 
Readily distinguished from related species by the villosulous upper surface 
of the leaves. 
Hoffmannia angustifolia Standl., sp. nov. 
Suffrutescent, glabrous throughout, the branches stout, subterete, the inter- 
nodes short ; leaves opposite, the petioles 1 to 2.5 em. long, the blades very nar- 
rowly elliptic, 10.5 to 20 cm. long, 3.5 to 5 em. wide, long-attenuate at the base, 
long-attenuate or subacuminate to the obtuse apex, subchartaceous, bright 
green above, slightly paler beneath, the lateral veins prominent, 12 to 14 on 
each side, arcuate-ascending at an obtuse angle; cymes sessile, few or many- 
flowered, dense, shorter than the petioles, the flowers sessile or nearly so, 
4-parted ; calyx tube 2 mm. long, the lobes lance-oblong, 1 to 1.5 mm. long, obtuse, 
minutely ciliolate; corolla 12 mm. long, glabrous, the lobes linear-oblong, obtuse, 
ascending, equaling or slightly shorter than the tube; anthers 3 mm, long. 
Type in the U. 8. National Herbarium, no. 888492, collected at Acatepeque, 
Department of Zacatepequez, Guatemala, altitude 1,290 meters, March, 1892, 
by John Donnell Smith (no, 2747). 
Hoffmannia psychotriaefolia (Benth.) Griseb., of Costa Rica, is closely re- 
lated, but is separated by its minute, deltoid calyx lobes and broad, cuspidate- 
attenuate leaf blades. 
Hoffmannia chiapensis Standl., sp. nov. 
Branches stout, obtusely quadrangular, glabrous, the internodes mostly elon- 
gate; stipules small deltoid; leaves opposite, the petioles slender, 1.7 to 6 cm. 
long, glabrous, the blades elliptic or elliptic-oblong, 10 to 19 cm. long, 4 to 7.5 em. 
wide, acuminate or attenuate at the base, acuminate at the apex, often falcate- 
acuminate, membranaceous, bright green above, glabrous, pale beneath, sparsely
