5. Sommera mesochora Standley, sp. nov. 
Tree, about 8 meters high; young branches stout, terete, densely pubescent 
with loose tawny hairs; stipules 20 to 35 mm. long, lance-ovate, attenuate, thin 
and scarious, sparingly strigose along the midnerve and margins, strigose-ciliate ; 
petioles 10 to 25 mm. long, densely pubescent with long loose hairs; leaf blades 
12 to 22 em. long, 3.5 to 8 cm. wide, oblong-oblanceolate to oblong-obovate, 
acuminate, sometimes rather abruptly so, gradually tapering from one-third the 
distance below the apex to a cuneate or very acute base, sparingly pubescent on 
the upper surface with very short appressed hairs, beneath rather densely 
pubescent with long, slender, loose or spreading, whitish hairs, ciliate; peduncles 
10 to 15 mm. long, densely pilose; cymes many-flowered, with several divaricate 
branches, the flowers rather densely clustered at the ends of the branches, short- 
pediceled ; bracts linear or lance-linear, the tips green, conspicuously reticulate- 
veined, abundantly pubescent with long loose hairs: ovary densely pubescent 
with long loose whitish hairs; calyx lobes 3 to 4 mm. long, oblong to broadly 
ovate, acutish to broadly rounded at the apex, strigose, conspicuously reticulate- 
veined; corolla white, 5 to 8 mm. long, densely and finely pubescent outside, 
loosely villous inside, the lobes one-fourth to one-third as long as the tube, ob- 
long, obtuse or acutish; style densely pilose at the apex; filaments inserted near 
the middle of the tube, about as long as the anthers; fruit not seen. 
Type in the U. 8S. National Herbarium, no. 675326, collected in a wet forest 
ravine, near KE] Boquete, Chiriqui, Panama, altitude 1,000 to 1,300 meters, 
March 2 to 8, 1911, by William R. Maxon (no. 4941). 
ADDITIONAL SPECIMENS EXAMINED: 
PanaMa: Near El Boquete, Chiriquf, alt. 1,000 to 1,300 meters, Pittier 3137. 
Costa Rica: Las Cruces de Boruca, February 19, 1898, Pittier (Inst. Fis.

This is closely related to the preceding species, but seems distinct in its long, 
narrow leaves of different outline, the densely pilose style, the long and loose 
pubescence, and the narrow, green bracts. 
NOTHOPHLEBIA, A NEW GENUS OF RUBIACEAE FROM 
COSTA RICA. 
Among the plants in the U. S. National Herbarium collected in 
Costa Rica by Mr. H. Pittier the writer has found one which at 
first glance recalls the genus Watsonamra, especially in the form 
of the leaves, these having the lineolate appearance or “ Moiréestrei- 
fung” characteristic of a group of four genera of the tribe Mus- 
saendeae. Although the specimen is only in flower, the form of the 
ovary clearly indicates that the plant is a member of this tribe, but
