Perianth-inbe obsolete ; outer segments obovate-cuneate, with a 

 reflexing limb ; inner similar, smaller, or in subgenus Vieusseuxia 

 small, tricuspidate. Stamens with anthers like those of Iris, but

 in Iris. — RootstocJc a globose corm, except in subgenus Dietes. 

 Leaves few, linear or ensiform. Flowers two or more in a cluster, 

 various in colour, usually fugitive. The line of demarcation 

 between Iris and JSIormi has been drawn in diflferent places by

 Iris belong entirely to the North Temperate zone, and Moraa to the 

 Cape and Tropical Africa, with one species Australian.
