OrpER XLIX. ROSACEA, Juss. 
(By W. H. Harvey). 
Calyx free or partially adnate with the ovary, its tube short or long, 
expanded or closed ; limb mostly regular, 3-4—5 parted, occasionally 
with a second external row of segments or adnate-bracts, alternating 
with the proper segments. Petals as many as the calyx-lobes or none, 
spreading, mostly equal. Stamens inserted in the throat of the calyx, 
indefinite, rarely definite, many or few ; filaments filiform, free. Ovary 
apocarpous (except in Grielum); carpels indefinite or definite, rarely 
only one, uniovulate, biovulate, or pluriovulate ; ovules anatropous. 
Styles one to each carpel, terminal or lateral ; stigmata simple or fea- 
thery. Fruit various ; usually of dry achenia, naked or enclosed in 
the calyx-tube ; in Rubus, of succulent, aggregated drupelets ; in 
Grielum a plurilocular capsule (in Spirea and its allies, follicular; in 
Pyrus and its allies a pome; in Prunus, &c., a drupe). Seeds without 
albumen ; embryo straight, with fleshy cotyledons. 
Herbs, shrubs, or trees, most abundant in the temperate and colder parts of the 
northern hemisphere, few tropical, and few in the south temperate zone. Leaves 
alternate, pinnately or digitately compound or parted, sometimes simple and entire. 
Stipules mostly present, adnate to the base of the ee Flowers variously dis- 
posed, rarely unisexual. To this important Order belong most of the garden fruits 
of Europe, as apples, pears, peaches, nectarines, apricots, plums, cherries, strawber- 
ries, and raspberries, as well as the ‘Garden's Queen,” the rose, which is the type 
of the group. The in od Saale possesses very few, and these more of the nature of 
weeds than flowers. e genus Grielum, placed here for want of a better location, 
looks more like a Geranium externally, but has perigynous petals and stamens, &c.
