STANDLEY—TROPICAL AMERICAN PHANEROGAMS., 185 
the form of the corolla is altogether different, the flowers being much larger than those 
of other members of the genus. 
Cassupa panamensis Standley, sp. nov. 
A small tree; young branches stout, obtusely quadrangular, densely tomentose with 
short tawny hairs; stipules 10 to 12 mm. long, triangular-oblong, acuminate, ciliate; 
petioles stout, 3 to 6.5 cm. long, cinereous-puberulent; leaf blades oval or oval-obovate, 
26 to 34 cm. long, 12 to 17 cm. wide, abruptly acuminate, the tips 25 to 30 mm. long, 
obtuse, shortly acuminate at the base, coriaceous, rugose, dark green on the upper 
surface and glabrous except for the puberulent veins, the lower surface densely white- 
puberulent, appearing tomentose, the lateral veins conspicuous, parallel, 18 to 20 on 
each side, the secondary veins finely reticulate; inflorescence a many-flowered thyrsi- 
form panicle 15 to 19 cm. long and about 11 cm. widé, on a stout peduncle 5 cm. long, 
or a few flowering branches present at the base of the peduncle, the branches of the 
inflorescence ascending, stout, compressed, 25 to 35 mm. Jong, densely hirtellous or 
tomentose with tawny hairs, the terminal flower sessile, the others on stout compressed 
pedicels 5 to 10 mm. long; bracts ovate, acute, 2 to 3 mm. long, ciliate, puberulent 
outside; calyx 1.5 to 2 mm. high, obscurely repand-dentate, ciliolate, glabrous; 
corolla white, the tube 52 mm. long, slightly dilated in the throat, finely and sparsely 
puberulent outside and verrucose, villous within the throat; corolla lobes 6, oblong, 
11 mm. long, 4.5 mm. wide or less, obtuse or acute, imbricated before anthesis, puberu- 
lent outside and within, bearded at the base; filaments 3 mm. long, inserted 28 mm. 
above the base of the tube; anthers 9 mm. long, abruptly acuminate at the apex; 
style slender, 32 mm. long, scaberulo-puberulent; stigma oblong, 5 mm. long; fruit 
elongate-globose, 8 or 9 mm. in diameter, 10 mm. high, 2-celled, smooth, glabrous; 
seeds numerous, 1 mm. in diameter, foveolate. 
Type in the U. 8. National Herbarium, no. 678965, collected along the Rfo Faté, 
Province of Colén, Panama, altitude 10 to 100 meters, July and August, 1911, by H. 
Pittier (no. 3889). Additional material is mounted on sheet 678964. 
This is the first species of the genus to be reported north of Colombia. It is related 
to Cassupa alba Schum. & Krause, described from the mountains of the interior of 
Colombia, but is distinguished by the longer corollas, which are tuberculate and puber- 
ulent outside rather than smooth and glabrous. The inflorescence is considerably 
narrower than that described for C. alba, but this may be an individual variation. 
Chomelia boliviana Standley, sp. nov. 
Chomelia tenuiflora Benth. ; Rusby, Mem. Torrey Club 3°: 45. 1893, not Benth. 
Journ. Bot. Hook. 3: 235. 1841. 
Branches slender, terete, grayish brown, the younger ones pubescent with short 
loose yellowish hairs, the older ones glabrate, furnished with numerous slender or 
stout spines 7 to 22 mm. long; stipules not seen, early deciduous; petioles slender, 
5 to 12 mm. long; leaf blades elliptic-oval to elliptic-oblong, 4 to 9 cm. long, 15 to 30 
mm. wide, acute or abruptly acuminate at the apex, acuminate or attenuate at the 
base, thin, bright green on both surfaces, sparsely pubescent on the upper surface with 
short fine appressed hairs, abundantly pubescent beneath, especially along the veins, 
with slender appressed hairs, the lateral veins prominent; peduncles axillary, 3 to 5 
cm. long, densely pubescent, bearing numerous sessile or subsessile flowers in a loosely 
branched cyme; bractssubulate, 2 to3 mm. long; calyx 2mm. long, densely appressed- 
pubescent, the 4 teeth unequal, about equaling the tube, narrowly triangular, acute; 
corolla tube slender, 12 to 20 mm. long, densely sericeous, the lobes 4 to 5 mm. long, 
oblong to oblong-ovate, acute or obtuse. 
Type in the U. 8. National Herbarium, no. 46974, collected near Yungas, Bolivia, 
in 1890, by Miguel Bang (no. 342). Also collected between Tipuani and Guanai,
