33. ROSE FAMILY. Order I10SACE.E. 

 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 

 cah'x. The seeds are few and their 

 ■whole kernel is embrvo, 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 

 folia"-e and bark, in the Almond sub- 

 familv. For fiijures illustratinfr 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. 

 202), Rose and Strawberry (Fig. 220 

 - 222), and the annexed figures. 



I. AL]\IOND Subfamily. Pistil only one, free from the calyx, becoming a stone-fruit. — Trees or 

 fihrubs Avith 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 {Amijfjdabis and Frunus), but under 

 several subgenera, here adopted for the convenience of the common 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, {Amyfjdalus) ^Almont>. 



Flesh pulpy: surface downy (or in Nectarine smooth), {Persiat) *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, (Armen)acn) * Apricot. 



Flat or flattish, generally edged: fruit smooth, with a bloom, {Pnmus) PLUi-M. 



Roundish or globular: fruit smaller, smooth, without a bloom. ( Cerasiis) Cherry. 



II. ROSE Subfamily. Pistils few or many (rarely only one), separate from each other and freo 

 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.
