 bricated scales, the innermost of which are sometimes petaloid. Stamens 

 equal in number to the inner sepals, and alternate with them ; anthers 

 roundish, 2-celled, the cells distinct, bursting longitudinally. Ovary superior, 

 seated in a fleshy disk, 3- 6- or 9-cel!ed ; ovules solitary, ascending. Style 1 ; 

 stigma radiating, the number of its rays corresponding with the cells of the 

 ovary. Fruit fleshy, seated in the persistent calyx, 3- 6- or 9-celled ; the 

 coating of the cells bony. Seeds solitary, ascending ; embryo taper, in the 

 axis of fleshy watery albumen; radicle inferior. Small shrubs, with heath-like 

 evergreen leaves, without stipules, and with minute flowers in their axils. 

 A very small group, comprising a few species from North America, the south 

 of Europe, and the Straits of Magellan. (Lindl. Nat. Sj/st. of Bot., p. 117.)
