STANDLEY—TROPICAL AMERICAN PHANEROGAMS, 133 
mm. long, densely appressed-pubescent with white hairs, the lobes rounded-ovate, 
obtuse; corolla white, 4 to 5 mm. long, appressed-pubescent outside, the lobes tri- 
angular-oblong, acute, about as long as the tube, spreading; fruit not seen. 
Type in the U. 8. National Herbarium, no. 676523, collected in forest between 
Gorgona and Gattin, Canal Zone, Panama, at an altitude of 10 to 50 meters, January 7, 
1911, by H. Pittier (no. 2266). 
Peculiar in the long whitish pubescence of the stems and inflorescence, the ap- 
pressed pubescence of the leaves, and the short, oblong inflorescence. 
Psychotria psychotriaefolia (Seem.) Standley. 
Cephaelis psychotriaefolia Seem, Bot. Voy. Herald 138. 1852-7. 
Typr Locaity: ‘‘In dense forests near Cruces, Province of Panama, and Chiram- 
bira, Darien.”’ 
DistripuTion: Panama. 
Shrub; young branches and inflorescence ferrugino-tomentulose; stipules united, 
thin, brown, deciduous, 1.5 to 2 cm. long, abruptly long-attenuate, ciliate, the apex 
usually bifid; leaf blades very shortly petiolate, obovate to obovate-oblong, 9 to 17 
cm. long, acute or short-acuminate, cuneate at the base, glabrous above, puberulent 
beneath, at least along the veins; inflorescence axillary or rarely terminal, sessile, 
the branches 1 to 6, 2 cm. long or less, each bearing 1 or several heads of sessile flowers, 
each head subtended by several more or less united bracts; corolla 3 mm. long; fruit 
4 to 5 mm. long, glabrous. 
Panama: Without locality, Seemann (Gray Herb.). Chagres, Fendler 58. Gatin, 
Hayes (Gray Herb.). 
Several sheets of some of the above collections have been examined. They do not 
agree in all respects with the original description, especially in the axillary inflores- 
cence. Itseems probable, however, that Seemann described the species from young 
material, which might account for some of the discrepancies. 
NEW SPECIES OF RUBIACEAE OF SEVERAL GENERA, CHIEFLY 
FROM PANAMA. 
The species described below are chiefly based upon the collections 
made in Panama, but a few are from other parts of tropical America. 
Two of the species, Cassupa panamensis and Stachyarrhena hetero- 
chroa, are of particular interest because they represent genera not 
previously reported from North America. 
Basanacantha subcordata Standley, sp. nov. 
Shrub or small tree with sweet-scented white flowers; branches slender, divaricate, 
glabrous, each bearing near the apex 2 slender or stout spines 5 to 7 mm. long; stipules 
free, 6 to 8 mm. long, ovate to oblong, obtuse or acute, mucronate, glabrous outside, 
densely white-sericeous within; petioles slender, 10 to 25 mm. long, canescent; leaf 
blades thin, dull green, oblong to ovate or broadly oval-ovate, 4 to 10 cm. long, 2.5 to 
6 cm. wide, very unequal, acute or abruptly acute, rarely obtuse, with a subulate tip 
1 to 2 mm. long, from rounded to cordate at the base, somewhat decurrent upon the 
petiole, strigillose or scaberulous on the upper surface, abundantly strigose and scab- 
rous beneath; staminate flowers 2 or more together at the end of the branches, sessile, 
the calyx tubular-campanulate, 7 mm. high, with 5 subulate lobes about 5 mm. long, 
abundantly pubescent, with long whitish appressed hairs; corolla tube 5 to 6 cm. 
long, slender, abundantly hirtellous outside, the lobes 2.5 to 4cm. long, ovate or lanceo- 
late, attenuate, sparingly pubescent; anthers slightly exserted; pistillate flowers 
solitary at the ends of the branches; ovary densely tomentose, the calyx tube tubular- 
campanulate, 6 mm. long, densely pubescent with whitish hairs, the lobes linear,
