MIRBEL'?! CLASSIFICATION OF FRUITS. 
Order 4th. Etairionnair, (from etairoi, associates,) contains com- 
pound fruits, proceeding from ovaries, bearing the styles ; this order 
contains two genera. 
Double Follicle, as in the milk-weed, (ascle 
pias,) having two folhcles, each formed of one 
valve, folded lengthwise, and adhering at its 
edges. 
Etairon*, having many seeds ranged round 
the imaginary axis of the flower, as the ranun- 
culus and anemone. 
Here is the fruit, (Fig. 99,) of the Aconitum, 
(monk's-hood,) which belongs to this order; it 
is composed of three pods united in one com- 
pound fruit; a, shows one of the valves in a 
dehiscent state ; b, represents a seed cut longi- 
tudinally. 
The Clematis is a caudate etairon, the PcBonia 
is divergent and dehiscent. 
Order 5th. Cenobionnair, (from koinobion, a community,) com- 
pound fruits without valves or sutures, proceeding from ovaries 
without any adhering styles ; this order contains but one genus. 
Cenobion,'\ includes fruit of the labi- 
ate plants and some others. Figure 
100, represents the pericarp of the ge- 
nus Gom/phia ; it is composed of five 
companions, a, as Mirbel calls each oi 
the one -celled divisions which stand 
around an ovoid germ, destitute of any 
style; 5, represents one of these divis- 
sions cut vertically; it contains one 
seed. 
Order 6th. Drupaces, simple, succu- 
This order has but one genus. 
Drupe, this pericarp is composed of a woody or bony panintern,"| 
called the nut, and of a panextern,| sometimes dry and membra- 
nous, at others fleshy or pulpy ; this character is peculiar to this fruit 
It may be regular or irregular, monocephalous or polycephalous, 
adhering to the calyx or free. The cherry has a pulpy panextern, 
the peach fleshy, the walnut woody. The amygdalis persica, Fig. 
101, a, is a succulent drupe, of a roundish form, and furrowed on the 
side ; the nut of this drupe is an ellipsoid, one-celled and one-seeded,
