94. Order 5th. Cenobionnaires (from Tcoinohion, a community), compound fruits 
without valves or sutures, proceeding from ovaries without any adhering styles ; 
this order contains but one genus. 1st. Cenobion indudes fruit of the labiate plants 
and some others. Fig. 106 represents the pericarp of the genus 
Gomphia; it is composed of live compaoiions, a, as Mirbel calls 
each of the one-celled divisions which stand around an ovoid 
pericarp ; b represents one of these divisions cut vertically, con- 
taining one seed. 
95. Order 6th. Drupaces, simple fruits, containing a nut. 
This order has but one genus. 1st. The Drupe is composed of a 
woody or bony panintern,^ called the nut, and of a panextern* sometimes dry and 
membraneous, at others fleshy or pulpy. It may be regular or irregular, mono- 
cephalous or polycephalous, adhering to the calyx, or free. The cherry has a pulpy 
panextern, the peach fleshy, the walnut woody. 
The AMYGDALis jt>em'ca, Fig. lOT, a, is a succu- 
lent drupe, of a roundish form, and furrowed 
on the side ; the nut of this drupe is ellipsoid, 
one-celled, and one-seeded ; b represents the 
peach deprived of one half of its pulpy ex- 
terior, or panextern, and exposing the nut or 
pauintern ; c represents the nut divested of 
one of its valves, and showing the seed d. 
96. Order 7th. Baccati (from bacca, a berry), simple, succulent fruits, contain 
ing many separate seeds. 
The genera in this order are 
the following : 1st. Pyridi- 
on (from perideo, signifying 
lying around), a regular, 
pome -like fruit, crowned 
with the adhering calyx. 
The pericarp has several 
cells, each of which con- 
tains one or more seeds ; 
the embryo has two cotyl- 
edons, wliich are large and 
fleshy. This genus con- 
tains the apple and pear. 
The apple (Fig. 108) has 
a round fleshy pericarp, 
crowned with the calyx; 
the seeds are inclosed in 
five carpels, or cells, ranged 
around in the axis of the 
fruit ; the cells are com- 
posed of membranaceous 
valves. The seeds are tu- 
nicated, or coated ; a represents an entire pyridion ; 6, the same cut vertically , 
and c, the same transversely. At c is seen a Une, sliowing the junction of the calyx 
with the fruit proper.\ 2d. Pcpo (from pepo, a melon), a regular monocephaloua 
fruit, with a radiating placenta, containing many seeds ; the panextern solid and 
dry ; the panintern pulpy ; it is globular in the watermelon, oblong in the cucum 
ber. Fig. 109 represents the cucumis anguria, prickly cucumber ; a is the entire 
* The panextern includes what is sometimes called epicarp and sarcocarp ; the panintern is the same 
as the endocarp. 
+ " A singular fact is observable in the fruit of the apple : when cut in slices transversely, it exliibits 
in its substance an exact re|)resentation of the five sepals which existed in the flower; I have never, in 
any botanical work, met with a notice of this phenomenon."
