Perianth rotate, with a short cylindrical tube and six subequal,

free ; anthers erect, linear-oblong. Ovary oblong or clavate, 3- 
celled; ovules crowded in the cells; style filiform, with three very short, 
spreading, flattened branches, stigmatose round the edges. Capsule 
rigid in texture, loculicidally 3-valved, oblong or cylindrical. Seeds 
small, globose or angled by pressure, 
Rootstock never bulbous. Herbs with the leaves in a distichous basal rosette, 
rarely undershrubs, with leaves not condensed. Leaves firm in texture, closely- 
ribbed, linear or ensiform. Inflorescence very various; flowers blue, clustered, 
appearing in succession ; clusters spicute, racemose or corymbose. Outer bracts
