XLIV. ROSACEA. 
iosa. 
Leaflets elliptical, doubly serrate, hairy, clothed beneath with rust-coloured 
glands, from which when bruised is emitted the peculiar fragrance for which the 
plant is noted. Sepals pinnate and bristly, as well as the peduncles. Corolla 
pink. Fruit scarlet, ovoid or oblong, bristly towards the base. 
Hab.: This European shrub has become naturalised between Stanthorpe and the border of 
N. S. Wales. 
Order XLV. SAXIFRAGES. 
Calyx free or adnate to the ovary, with 4 or 5 valvate or imbricate lobes or 
segments. Petals as many as calyx-lobes, valvate or imbricate, sometimes very 
small or wanting. Stamens as many or twice as many as calyx-lobes, rarely 
fewer and very rarely indefinite, inserted with the petals on or outside a 
perigynous or epigynous disk or rarely hypogynous. Ovary more or less adnate 
to the calyx, or if free usually attached by a broad base, either 2 to 5 -celled or 
with 2 to 5 parietal placentas, very rarely contracted at the base or apocarpous ; 
ovules usually several, very rarely solitary in each cell or to each placenta ; styles 
as many as cells or placentas, distinct or rarely united. Fruit capsular or very 
rarely succulent and indehiscent. Seeds usually small, with a copious albumen 
and small or terete straight embryo, very rarely larger and without albumen. — 
Herbs shrubs or trees. Leaves alternate or opposite, simple or compound, with 
or without stipules. Flowers usually regular and hermaphrodite. 
A large Order, ranging over nearly the whole world, the shrubby or arborescent genera chiefly 
tropical, the herbaceous ones from the more temperate or colder regions of the northern 
hemisphere, with a few extratropical southern genera or species. The Order includes a great 
variety of forms, evidently connected with each other, but difficult to unite by a common character 
which shall separate them from several other Calyciflorous and some Thalamiflorous Orders 
into which they appear sometimes to pass. There is especially no one character to distinguish 
them from Rosacea which has not some exception, although the greater number of genera differ 
from that Order in their definite stamens, united carpels with free styles, and copious 
albumen. — Benth.
