Order XLIY. ROSACEA. 
Calyx either enclosing the ovary, or adhering to it, or quite free, 5 rarely 4- 
lobed, with the addition in a few genera of as many external accessory lobes. 
Petals as many as true calyx-lobes, inserted on the calyx at the base of the lobes, 
or in Stylobasium (Western Australia) hypogynous. Stamens indefinite, rarely 
few, inserted with the petals, free. Ovary of 1, 2 or more carpels, usually 
distinct at the time of flowering, but sometimes combined even then into a 
single 2 to 5-celled ovary, which is then always inferior or combined with the 
calyx ; ovules 1 or 2, rarely more in each carpel ; styles or sessile stigmas 
distinct. Fruiting-carpels either free or variously combined with each other or 
with the calyx indehiscent or rarely opening along the inner edge. Seeds 
without albumen or rarely albuminous ; embryo with large cotyledons and a 
short radicle. — Trees, shrubs, or herbs. Leaves alternate, simple or compound, 
almost always with stipules. Flowers in axillary or terminal cymes or solitary, 
very rarely in simple racemes. 
A numerous Order, widely spread over the globe, but more in the temperate and cooler parts 
of the northern hemisphere than within the tropics or in the southern hemisphere. — Benth.
