they went, 
Triton his trompet shrill before them blew.

There are about 84 species, all natives of South Africa. 
They are ornamental plants from a scaly or mostly solid 
and fiber-bearing bulb, producing a simple or slightly 
branching stem and a few narrowly linear or sword-shaped 
leaves, which are often falcate. The handsome yellow, 
orange, blue, or white flowers are sessile, and scattered 
along a simple or branching peduncle, each flower soli- 
tary in a short membranous spathe. They are known In 
cultivation by the generic name Tritonia, and sometimes 
by a former generic name Moiilbntia.
