Order LXXXVIL* EMPETRACEiE. The Crowberry Tribe. 
Empetre^, Nutt. Gen. 2. 233.; Don. in Edinb. New Phil. Journ. (1826) ; Hooker in Bot. 
Mag. t. 2758. (1827) ; Lindley’s Synopsis, 224. (1829) ; Bartl. Ord. Nat. p. 372. 
(1830); Arnott in Edinb. Ency cl. 129. (1832). 
Essential Character. — Mowers unisexual. Sepals hypogynous imbricated scales. 
Stamens equal in number to the inner sepals, and alternate with them ; anthers roundish, 
2-celled, the innermost of which are sometimes petaloid, the cells distinct, bursting longi- 
tudinally. Oi'ary superior, seated in a fleshy disk, 3- 6- or 9-celled; 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 ot 
the cells bony. Seeds solitary, ascending ; embryo taper, in the axis of fleshy watery albu- 
men ; radicle inferior. — Small acrid shrubs with heathlike evergreen leaves without stipules ; 
and minute ^owm in their axils. 
Affinities. According to Don this order holds a kind of intermediate 
place between Euphorbiaceae and Celastraceae, agreeing in habit with the for- 
mer, especially with Micranthea, and some species of Phyllanthus, more than 
with the latter. In this view Arnott and Bartling concur. Until lately I 
had an idea that a relation might be better established with Urticaceae and 
Myricaceae, but I now feel that I was wrong, and give it up. 
Geography. A very small group, comprising a few species from North 
America, the south of Europe, and the Straits of Magellan.
