CEPHAELIS (from kephale, a head; in reference to

shrubs, rarely perennial herbs, mostly natives of tropical 
America, a few African, and two or three from Asia and 
Oceania. Heads of flowers terminal or axillary, sessile or 
pedunculate, subtended by an involucre of from two to 
eight bracts, which are disposed in a cruciately opposite 
manner; corolla funnel-shaped. Leaves ovate, acute, pe- 
tiolate ; stipules free or combined. They thrive in a com- 
post of sandy, fibry peat, leaf soil, and lumpy loam, with - 
thorough drainage. Cuttings of firm young shoots will root 
in sandy soil, under a hand glass, in moist stove heat.
