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. 

 (Honor of J. Hooker, an English botanist.)

fixed; capsule subsessile.

staminodia deeply cleft, projecting beyond the anthers; seeds usually i in each 



cell. W. C. H. pulcheUa (OOKOW) 



CC. Scape 3-6 dm. high, somewhat scabrous; umbel never elongated; staminodia 



entire, obtuse, about equaling the anthers; seeds several in each cell. U.

 bracted racemes or umbel-like clusters, usually large ; pedicels not jointed, 

 with foliaceous bracts. Perianth funnelform. Stamens 6, hypogynous, 

 included; anthers versatile, extrorse. Stigma 3-lobed. Capsule sessile,
