83. ROSE FAMILY. Order ROSACEZ. 
A large and most important family of plants, distinguished by having alternate leaves 
with stipules, and regular flowers; their generally 5 petals (sometimes wanting) and sta- 
mens (generally numerous, at least 
above 10) inserted on the persistent 
calyx. The seeds are few and their 
whole kernel is embryo, as is seen in 
an almond (Fig. 36), Apple-seed, or 
Cherry-seed (Fig. 38), &c. The 
family furnishes some of our most 
esteemed fruits: all the plants are 
innocent, except the strong-scented 
foliage and bark, in the Almond sub- 
family. For figures illustrating this 
family, see those of Cherry-blossom 
(Fig. 193), Hawthorn-blossom (Fig. 
194), the fruit of Apple and Quince, 
(Fig. 200 and 201), Peach (Fig. 
830. Section of a Rose-bud. 361. American Crab-Apple. 202), Rose and Strawberry (Fig. 220 
— 222), and the annexed figures. 
I. ALMOND Sunramity. Pistil only one, free from the calyx, becoming a stone-fruit. — Trees or 
shrubs with simple leaves ; the bruised bark and foliage with a peculiar aromatic scent and flavor. — 
The plants of this division are all ranked under two great genera (Amygdalus and Prunus), but under 
several subgenera, here adopted for the convenience of the commen names. 
Calyx with a rather deep cup. Petals rose or red-purple. Stone of the fruit rough. 
Flesh of the fruit becoming a dry husk. We have the dwarf Flowering-Almond in 
gardens, with double flowers. It does not form fruit here, (Amygdalus) * ALMOND. 
Flesh pulpy: surface downy (or in NECTARINE smooth), (Persies) *PEACH. 
Calyx with a short and broad'cup. Petals white. Stone of the fruit, smooth, and 
Flattened, with grooved edges: skin of the fruit downy, (Armeniaca) * Apricot. 
Flat or flattish, generally edged: fruit smooth, with a bloom, (Prunus) Pium. 
Roundish or globular: fruit smaller, smooth, without a bloom, ( Cérasus) CHERRY. 
IL ROSE Susramity. Pistils few or many (rarely only one), separate from each other and free 
from the persistent calyx, but sometimes (as in the Rose, Fig. 360) enclosed and concealed in its tube. 
Stipules generally united with the bottom of the leafstalk on each side.
