STANDLEY—TROPICAL AMERICAN PHANEROGAMS. 205 
Type in the U. S. National Herbarium, no. 677448, collected in forests along 
the Rio Ladrillo, above El Boquete, Chiriquf, Panama, altitude 1,200 to 1,300 
meters, March, 1911, by H, Pittier (no. 3056). 
Hoffmannia calycosa Donn. Smith, of Guatemala, is a near relative, but 
is distinguished by the long, linear calyx lobes, 
Hoffmannia tonduzii Standl., sp .nov. 
Shrub, the branchlets slender, subterete, glabrous, the internodes elongate; 
stipules minute; leaves opposite, the petioles stout, 2 to 6 mm. long, glabrous, 
the blades oval-elliptic or broadly obovate-elliptic, 6.5 to 12 cm. long, 3.5 to 5.5 
cm. wide, acute or cuneate at the base, acuminate or cuspidate-acuminate at 
the apex, with an obtuse acumen, membranaceous, glabrous, dark green above, 
paler beneath, the lateral veins slender, about 8 on each side, subarcuate ; 
cymes few-flowered, sessile or subsessile, the pedicels in fruit up to 5 mm. long, 
some of the flowers usually sessile; calyx glabrous or sparsely puberulent, the 
tube turbinate, angulate, 2.5 mm. long, the lobes narrowly triangular, 1 to 1.5 
mm. long, acute; corolla 6 to 7 mm. long (perhaps longer), glabrous outside, 
the lobes lance-oblong, acute, twice as long as the tube. 
Type in the U. S. National Herbarium, no. 941386, collected in forests of 
Las Vueltas, Tucurrique, Costa Rica, altitude 635 to 700 meters, May, 1899, by 
A. Tonduz (no. 13373). . 
Distinguished from H. panamensis, described above, by the few-flowered 
inflorescences, elongate pedicels, turbinate calyx tube, and proportionately 
broader heaf blades. * 
Hoffmannia orizabensis Standl., sp. nov. 
Low shrub, the branches slender, decumbent, rufous-villosulous when young ; 
leaves opposite, the petioles slender, 0.5 to 2 cm. long, rufous-villosulous or 
puberulent, the blades elliptic or elliptic-oblong, 3 to 8 cm, long, 1 to 8 cm. wide, 
acute at the base, acute or subacuminate at the apex, membranaceous, deep 
green on the upper surface, rufous-villosulous along the costa, conspicuously 
white-striolate, paler beneath, rufous-villosulous along the veins, the costa 
slender, prominent, the lateral veins slender, prominulous, 7 to 9 on each side, 
ascending, strongly arcuate; inflorescence 4-flowered, the peduncles slender, 
about 1 cm. long, rufous-villosulous, the pedicels slender, 2 to 3 mm. long; 
calyx sparsely villosulous, the tube oblong-turbinate, 2.6 mm, long, the lobes 
narrowly triangular, acute; corolla 12 to 13 mm. long, sparsely villosulous 
outside, the throat ampliate, the lobes ovate-oval, obtuse or rounded, half as 
long as the tube; anthers obtuse. 
Type in the Gray Herbarium, collected in the region of Orizaba, Veracruz 
or Puebla, Mexico, in 1855, by Mueller (no, 1359). 
Hoffmannia aginis Hemsl., of Costa Rica, known to the writer only from the 
original description, must be closely related to the present plant, but it is de- 
scribed as having a corolla only 6 to 8 mm. long, with lobes slightly longer 
than the tube. 
Hoffmannia decurrens Standl., sp. nov. 
Shrub, the branches grayish, the branchlets stout, subangulate, rufous- 
villosulous or glabrate, the internodes mostly elongate; stipules deltoid, minute ; 
leaves opposite, the petioles stout, 0.5 to 3 cm. long, villosulous or glabrate, 
the blades oblong-oblanceolate or narrowly elliptic, 7.5 to 16.5 cm. long, 1.8 to 
4.5 cm. wide, long-attenuate to the base, acute or short-acuminate at the apex, 
membranaceous, dark green above, glabrous, paler beneath, villosulous along 
the veins or finally glabrate, the lateral veins slender, arcuate-ascending, 8 to 
10 on each side; cymes usually many-flowered, sessile or short-pedunculate,
