Lindl. Bot. Reg. 15: under pi. 1293. 1830. 



Scapes slender, erect, arising from a fibrous-coated, depressed corm. Leaves few, all basal, 

 linear, thin and flat. Flowers in a close or open bracteate umbel, blue or purple. Perianth-

 lateral teeth ; anthers erect, more or less versatile. Ovary on a slender stipe. Capsule beaked 

 by the persistent style ; seeds black, angled, several in each cavity. [Greek, alluding to the 

 perfect ternary arrangement of the partG of the flower.]
