I, MORZA, Linn, 
Perianth funnel-shaped, without any proper tube; segments un- 
equal, more or less distinctly unguiculate, 3 outer obovate-oblong, 
3 inner always smaller, usually oblanceolate, Stamens opposite 
the style-branches ; filaments nearly always more or less connate ; 
anthers linear. Ovary 3 celled, obtuse or rostrate; ovules crowded, 
superposed ; style-branches large and petaloid, as in Jris, with the 
stigma at the base of the petaloid crests. Capsule ovoid or ellipsoid, 
dehiscing loculicidally. Seeds ovoid or subglobose, often angled by 
pressure, 
Rootstock, usually a tunicated corm, rarely a rhizome, Produced leaves usually 
few, linear sometimes forming a distichous rosette ; upper rudimentary sheathing. 
Spathes cylindrical; outer valves green, more or less rigid. Flowers smaller and 
more tive than in Iris, usually lilac or yellow, 
_Disrris. Species about 60, many Tropical African; the rest inhabiting 
Madagascar and Australia. The line of limit between Iris and Morea bus been 
differently drawn by different authors, but the two genera are extremely close, 
Subgenus I. Eumorn#a. Rootstocka corm. Inner segments of the perianth 
oblanceolate-unguiculate. Orary not produced into a beak. 
ACAULES. Spathes sessile in the centre of the rosette of leaves.
