Species Cephaelis dichroa (Standley) Standley
PlaceOfPublication Publ. Field Columbian Mus., Bot. Ser. 4: 296. 1929.
Synonym Evea dichroa Standley, Contr. U.S. Natl. Herb. 18: 124. 1916. TYPE: Panama, Pittier 3218 (US, holotype).
Description Glabrous shrubs, to 2 m tall. Leaves elliptic, 8.5-13.0 cm long, to ca. 3.2 cm wide, acuminate at the apex, cuneate at the base, the lateral veins ca. 12, stiffly papyraceous, concolorous, often drying yellowish, glabrous; petioles to 3 cm long, wiry, often flexuous; stipules connate, ca. 3.5 mm long, the body com- pressed cylindrical, each part with 2 widely spaced, erect, obtuse lobes about as long as the sheath. Inforescences terminal, the peduncle 5-8(-9) cm long, ter- minated by 3 heads of flowers, the trio subtended by 2 large obovate bracts, to 2.2 cm long, ca. 1.8 cm wide. Fruits subrotund to 0.8 cm wide. Cephaelis dichroa is known only from Panama. Standley's original description of the inflorescences and flowers may help in the understanding of this species: Peduncles terminal or rarely also axillary, 3-9 cm long; bracts 15-20 mm long, rounded ovate, acutish, slightly united at the base, green or tinged with red or yellow, subtending 3 pedunculate heads, the peduncles 3-25 mm long; each sec- ondary head subtended by 2 orbicular-rhombic bracts 12-15 mm long, these yel- low or tinged with purple, each head consisting of 3 flowers, each flower sub- tended by an oblong obovate acute bract 10-12 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, oblong, acute; corolla yellowish white, the tube 10 mm long and 2 mm in diameter, the 5 lobes 2.5-3 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; fruits not seen."
Habit shrubs
Note Another collection, Mori & Kallunki 2732 (MO), from between Fort San Lo- renzo and Fort Sherman near Pavon Road junction with Road 82 (S 2), Canal Zone, may be C. dichroa. It is 21/2 m tall with bracts magenta and fruits black, but its sea level locality argues against such determination.
