cell, opening by a sutural dehiscence on the inner side, and 
bearing seeds at the base, or along the suture. Ex. peony, col- 
umbine, silk-weed. 
6. Drure (stone-fruit) is one-celled, one or two seeded, inde- 
hiscent, with a hard and bony endocarp (stone), and a moist and 
pulpy epicarp and sarcocarp. Ex. plum, cherry, peach. It also 
includes those fruits which have a fibro-fleshy, or even coria- 
ceous epicarp, as the walnut, butternut, which kinds of fruit are 
called drupaceous. 
7. The Nout is a hard, dry, indehiscent shell, proceeding from 
an ovary which is two or more celled, and two or more ovuled, 
but becoming by suppression one-celled, and one-ovuled (110, @). 
It differs from the Drupe, in wanting the soft, succulent cover- 
ing. Instead of this it is seated in a kind of persistent involu- 
cre, called a cupule. Ex. chestnut, oak, beech, hazle. 
8. Caryopsis (kernel). This is a thin, dry, one-celled peri- 
carp, inseparable from the seed which it encloses. Ex. maize, 
wheat, Carex. When it is not inseparable from the seed, it is 
called a wtricle, as in the pig-weed (Chenopodium). 
9. An ACHENIUM is a small, dry, hard, one-celled pericarp, dis- 
tinct from the seed which it contains. Ex. Borago, Ranun- 
culus, Aster, and the Composite generally. 
10. Samara (winged fruit). It consists of a dry, indehiscent, 
one-seeded pericarp, with a wing-like appendage. Ex. birch, 
maple. : 
11. A pyxis (box) is a capsule which opens by a circum- 
sessile dehiscence (115; 5), so as to appear like a little cup with 
alid. Ex. plantain (Plantago), purslane (Portulaca). 
12. Pome (apple). This is a fleshy, indehiscent pericarp, 
formed of the permanent calyx, containing several cartilaginous 
carpels, or cells, which enclose the seeds. Ex. apple, pear, 
quince. , 
13. The prro (gourd) is an indehiscent, fleshy fruit, proceed- 
ing from a compound ovary, either one-celled, or entirely filled 
with pulp. Ex. cucumber, melon, pumpkin. 
14. Berry (Bacca), a succulent, pulpy pericarp, holding the 
seeds loosely within, with no other covering than its own soft
