 long in fruit, appendaged by 4 tufts of spreading hairs; 

 calyx-lobes acute, pubescent; utricle loose, the pericarp 

 readily separating from the large seed.

 stigmas 2, filiform, connate at the base. Utricle obovate to cuneate, winged or crested at 

 the apex, enclosed in the perianth. Seed erect; embryo horseshoe-shaped; endosperm 

 copious. [Greek, mild to the taste.]

 Stamens 1-3, rarely more, and one of them longer. Ovary ovoid, styles 2. Utricle ellipsoid, 

 mostly plano-convex, the pericarp firmly adherent to the vertical seed, its margins acute or 

 winged. Embryo annular in the somewhat fleshy endosperm, its radicle pointing downward.
