CYANOTIS (from kyanos, blue, and ous, an ear; 
alluding to the petals). Syn. Tonningia. ORD. Comme- 
limacem. A genus containing about thirty species of 
pretty stove or greenhouse plants, allied to Tradescantia. 
Flowers nearly regular; perianth segments six; exterior 
ones nearly equal, navicular, connate at base; inner three 
long, petaloid, connate by the claws. Leaves various, 
small or middle-sized, sheathing at the base. Cyanotis 
require a rich loamy soil, and good drainage. They are 
propagated chiefly by young cuttings, inserted in sandy 
soil, in brisk heat. Several species are enumerated.

upright filaments, densely clothed with deep blue hairs. August.
