CANTHUS (from thyrsos, a thyrse, and

Thyrse Flower. Syn. Odontonema. ORD. Acanthacee. 
A genus comprising about a score species of stove, erect 
herbs or shrubs, natives of tropical America. Flowers 
red, fascicled in the axils of the bracts, pedicellate ; 
calyx short, somewhat five-parted ; corolla tube elongated ; 
limb sub-bilabiate, four-cleft; stamens two, affixed above 
the middle of the tube; fascicles or cymes disposed in 
a thyrse. Leaves opposite, entire, often large. The 
species known to cultivation are described below. They 
thrive in a compost of about equal parts of loam and 
leaf soil. Propagated by cuttings, inserted, preferably 
in single pots, in spring, and placed in a close, warm 
frame. Young plants should be pinched, to encourage 
a bushy growth. Some of them may be cultivated in 
frames during the summer, but require a stove tempera- 
ture in winter. at
