Double Follicle^ as in the milk-weed, {ascle 
pias,) having two follicles, each formed of one 
valve, folded lengthwise, and adhering at it? 
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-

is divergent and dehiscent. 
Order 5th. Cenobionnair, (from koi7iohion^ 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

nus Gomphia ; it is composed of five 
com,pa7iions, a, as Mirbel calls each .of
