Xlvi GARDEN BOTANY. 



Pistils many (becoming bony achenia in fruit), enclosed in the hollow 

 tube or cup of the calyx, which is fleshy, and becomes thick 



and pulpy in fruit. Prickly shrubs 9. ROSA. 



Pistils 2 to 5 combined into one by their ovaries to make a compound 

 ovary, which is coherent with the thick tube of the calyx ; this 

 becomes fleshy or pulpy in fruit : all shrubs or trees. 

 Only one ovule and one seed in each cell, the latter stony in fruit. 

 One thick stone in the fruit, having 2 to 5 cells. Man. p. 123. CRAT^OUS. 



Three to five small and 1-sceded stones iu the fruit. . . 10. COTONEASTKR. 



Two or few ovules and seeds in each cell. 11. PYRUS. 



Many ovules or seeds in each cell 12. CYDONIA. 



1. Amyg'dalu.8 nana, DWARF ALMOND. The DOUBLE-FLOWERING va- 

 riety is common in gardens (but not the single), its numerous rose-colored 

 flowers appearing early in the spring, before the narrow and lanceolate leaves. 



A. Persica, the PEACH, with rose-pink-colored flowers, broadly lance- 

 olate leaves, and downy-coated fruit. 



Var. laevis, the NECTARINE, has the fruit smooth, like a Plum, but came 

 originally from the Peach. 



2. Primus, PLUM, CHERRY. Besides Nos. 1, 7, and other species in the 

 Man. p. Ill, 113, the following are common in cultivation : 



P. Armeniaca, the APRICOT, with almost sessile white flowers appear- 

 ing much before the leaves, which are ovate and somewhat cordate, the yel- 

 lowish fruit with a velvety surface. In this respect it is like the preceding 

 genus ; but the flowers, the smooth stone, &c. are as in the Plum. 



P. Domestica, the GARDEN PLUM, of many varieties, has thornless 

 branches and lanceolate-ovate leaves ; it is thought to be a long-cultivated 

 production of P. instititia, the Bullace Plum, and this a variety of the SLOE, 

 Man. p. 112. 



P. Cerasus, the GARDEN CHERRY, with ovate-lanceolate or oblong- 

 ovate smooth and veiny leaves, and flowers in sessile umbels, opening at the 

 same time as the leaves ; this is the original stock as well of the OXHEART 

 or DUKE CHERRY as of the SOUR CHERRY, MORELLO, &c. 



3. Poterium Sanguisqrba, GARDEN BURNET. A common low peren- 

 nial in country gardens, with small and ovate deeply-toothed leaflets, and a 

 head of greenish or purplish flowers, the lower ones staiuiuate, the upper ones 

 pistillate. 



4. Kerria Japonica, is called CORCHORUS in the gardens, where it is a 

 common shrub, with ovate and pointed coarsely toothed leaves, and full 

 double yellow flowers. The state with single or natural flowers has lately 

 been introduced from Japan. 



5. Spiraea. Man. p. 113. Several of our wild species and the following 

 exotics are cultivated for ornament. 



* Shrubs or undershrubs. 



S. trilobata. Low shrub, with recurved branches ; leaves smooth, glau- 

 cous, rounded, and cut-lobed ; flowers very many in umbel-like corymbs, 

 white, showy. 



S. hypericifolia, ITALIAN MAY, or ST. PETER'S WREATH. Shrub, 

 with long recurved branches ; leaves small, cuncate-oblong, a little eremite or 

 lobed at the end ; flowers small, white, in small umbels. 



S. Douglasii, of Oregon, is coming into the gardens : it resembles S. 

 tomentosa (Man. p. 114), but has longer, narrower, and blunter leaves, and 

 deeper rose-purple flowers.
