HOOKERA (Fool's Onion) 



Perennial ; corms with fibrous membranes, coated ; stem scapose. Leaves 

 narrow. Flowers blue or purple or white or yellow, solitary or, in a bracted 

 umbel, on jointed pedicels. Stamens either 6, of which i is opposite each 

 perianth segment and more or less united with it; or only 3, the 3 outer 

 replaced by staminodia. Style persistent, about equaling the anthers; 

 stigmas 3, short, divergent. Capsule ovate-oblong. Seeds angled. —
