124 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
along the veins with slender, loose, rather long, dirty white hairs, the lateral veins 
conspicuous, 27 to 32 on each side, parallel, anastomosing near the margin, finer 
secondary veins present between the primary ones and parallel with them, connected 
with the primary veins by fine transverse veinlets at regular intervals; peduncles 
terminal, 6 to 13 cm. long, very densely covered with long, fine, spreading, dirty white 
hairs; bracts orbicular-rhombic, 1 cm. long, apiculate, sericeous, green, each pair 
including 3 short-pedunculate heads 10 to 15 mm. in diameter, the inner peduncles 
2 to 13 mm. long; bractlets green, oval-obovate, 10 mm. long, obtuse, apiculate, seri- 
ceous on both surfaces; calyx twice as long as the ovary, the two together 3 mm. long, 
densely sericeous, the lobes ovate, acute; corolla white, the slender tube about 7 mm, 
long, the lobes 2.5 mm. long, oblong, pubescent outside; fruit not seen. 
Type in the U.S. National Herbarium, no. 530768, collected in sunny places in the 
forest near Cérdoba, Dagua Valley, Pacific Coastal Zone, State of Cauca, Colombia, 
altitude 30 to 100 meters, December, 1905, by H. Pittier (no. 581). ; 
Apparently not closely related to any other species; well distinguished by the 
form of the inflorescence and the abundant pubescence. The venation of the leaves 
is very similar to that found in ferns of the genus Campyloneurum. 
Evea dichroa Standley, sp. nov. 
Glabrous branched shrub 1.5 to 2 meters high; branches slender, nearly terete; 
stipules united at the base, green, persistent, 3 to 4 mm. long, deeply bilobate, the 
lobes oblong, obtuse; petioles slender, 1.5 to 2.5 cm. long; leaf blades elliptic or 
oblong-elliptic, 5.5 to 10.5 cm. long, 1.5 to 3.5 cm. wide, acuminate at the apex, acute 
or acuminate at the base, firmly herbaceous, bright green on the upper surface, slightly 
paler beneath, prominently veined, the lateral veins 9 to 12 on each side, parallel; 
peduncles terminal or rarely also axillary, 3 to 9 cm. long; bracts 15 to 20 mm. long, 
rounded-ovate, acutish, slightly united at the base, green or tinged with red or yellow, 
subtending 3 pedunculate heads, the peduncles 3 to 25 mm. long; each secondary head 
subtended by 2 orbicular-rhombic bracts 12 to 15 mm. long, these yellow or tinged 
with purple, each head consisting of 3 flowers, each flower subtended by an oblong- 
obovate acute bract 10 to 12 mm. long and an oblong-linear bracteole somewhat 
shorter; flowers sessile; calyx 3 mm. long, twice as long as the ovary, somewhat oblique, 
yellow, deeply 5-lobed, the lobes ovate to oblong, acute; corolla yellowish white, the 
tube 10 mm. long and 2 mm. in diameter, the 5 lobes 2.5 to3 mm. long, oblong, obtuse; 
stamens included, inserted in the middle of the tube, the filaments about as long as 
the anthers, these linear, 2.5 mm. long; fruit not seen. 
Type in the U. 8. National Herbarium, no. 677615, collected in the humid forest of 
Cuesta de las Palmas, southern slope of Cerro de la Horqueta, Chiriquf, Panama, at an 
altitude of 1,700 to 2,100 meters, March 17 to 19, 1911, by H. Pittier (no. 3218). 
Known also from specimens collected in humid forest of Alto de las Palmas, southern 
slope of Cerro de la Horqueta, Chiriquf, altitude, 2,100 meters, Pittier 3266. 
In.the type collection the bracts are purple or greenish purple, more or less tinged 
with yellow, while in the second collection they are pale yellow or greenish yellow. 
The species seems very distinct in the form of the inflorescence, although some of the 
Brazilian species likewise have 3-parted heads. 
DUGGENA AN OLDER NAME THAN GONZALAGUNIA. 
There is a small genus of tropical American Rubiaceae which was 
long known under the name Gonzalea Pers. In recent years the 
name Gonzalagunia Ruiz & Pavon has generally been adopted for it, ' 
this name (1794) clearly having precedence over that of Persoon 
(1805). There seems no valid reason why the oldest generic name,
