POPULAR FLORA. 



1. Maryland Senna. Root perennial; stems 3° or 4° high ; leaflets 6 to 9 pairs, lance-oblong, 1' or 



more long, used for medicine instead of the imported senna. Rich soil. C. Marikimlica. 



2. Partkidge-Pea S. Annual, low, spreading; leaflets 10 to 15 pairs, linear-oblong, V long; flower.= 

 large and showy ; anthers 10, six of them purple. Sandy fields. C. Vlmmifi-nsln. 



3. Sensitive S. Flowers small, short-stalked; anthers only 6 : otherwise like the last. C. nicliiaus. 



33. ROSE FAMILY. Order ROSACEJE. 

 A large and most important family of plants, distinguished liy having alternate leayef 

 with stipules, and regular flowers ; their generally 5 petals (sometimes wanting) and sta- 

 mens (generally numerous, at least 

 above 10) inserted on the persistent 

 cal}-x 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 furnislus 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. 19.'i), Hawthorn-blossom (Fig. 

 194), the fruit of Apple and Quince, 

 (Fig. 200 and 201), IVach (Fig. 

 202), Rose and Strawbeny (Fig. 220 

 - 222), and the annexed figures. 



I. ALMOND Subfamily. 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 (Amijinliilus and Prunus), 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, (Aiiiijr/ilnlus) *Almond. 



Flesh pulpy: surface downy (or in Nectarine smooth), (/'(•/■siV.<) *Peacii. 



Cal3'x with a short and broad cup. Petals white. Stone of the fruit smooth, and 



Flattened, with grooved edges: skin of the fruit downy, {Armen'iacn) *Aprich>t. 



Flat or flatfish, generally edged: fruit smooth, with a bloom, {Prunus) Plum. 



Roundish or globular: fruit smaller, smooth, without a bloom, {Cf'ras/is] Cherry. 



II. ROSE Subfamily. 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) enclusud and concealed in its tube 

 Stipules generally united with the bottom of the leafstalk on each side.
