2. P. clypearia, Bentlu in Lond. Jonni. Bot. iii. 209. A tall tree, the 

 younger branches very acutely angular, and as well as the inflorescences sligiitly 

 pubescent. Leaves of 4 to 6 pair of pinnas. Leaflets in the lower pinnce 3 

 to 6 pair, in the terminal ones 10 to 12 pair, all obliquely ovate, nearly 

 rhomboid or trapezoid, obtuse or acute, the terminal ones about \\ in. long, 

 the others smaller. Panicle large and terminal. Peduncles short, clustered 

 one above another ; the common bract reduced to a short stalk with a large 

 gland. Elowers few together in small heads, the corolla about 2 lines long, 

 the stamens three times as long. Pod forming 2 or 3 coils of 1^ in. diameter, 

 indented between the seeds on the outer edge. — Biya dimidiata, Hook, and

OiiDEE XXXVII. ROSACEA. 



Sepals 5, rarely 4, united into a lobed calyx, either enclosing the ovary, or 

 adhering to it, or quite free. Petals as many, inserted on the calyx at the base 

 of its lobes or rarely none. Stamens usually numerous, 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, or rarely 

 more, in each carpel. As the fruit enlarges, the carpels either remain free, or 

 are variously combined with each other or with the calyx ; when ripe, they 

 either remain indehiscent or more rarely open on their inner edge. Seeds 

 without albumen. Embryo mth large cotyledons, and a short radicle. — Trees, 

 shrubs, or (in genera not included in the present Flora) herbs. Leaves alter- 

 nate, mostly toothed or divided, the stipules seldom wanting, and often leaf-like. 

 Plowers either solitary at the end of the year's shoots, or in cymes or panicles, 

 or more rarely in lateral branches or racemes. 



A nmnerous 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.
