into the mouth of the corolla, it is meant that they cohere 
with the corolla as far as the mouth, where they first separate 
from it ; when in the Rose they are said to be inserted into 
the calyx, it is meant that they cohere with the calyx up to a 
certain point, where they separate from it; when in Arabis 
they are said to be inserted under the pistil, it is meant that 
they cohere with neither calyx nor corolla, but stand erect 
from the point which immediately produces them ; and finally, 
when in Orchis or Heracleum they are said to be inserted into 
the pistil, such an expression is to be taken as meaning that 
they cohere with the pistil more or less perfectly. For ex- 
cellent arguments in support of this hypothesis, see DunaFs 
Considerations sur la nature et les rapports de quelques uns des 
Organes de la Fleur, I do not use them, or any such, here, 
because it seems to be so self-evident a fact, when once 
pointed out, as to require no demonstration, and can easily 
be ascertained to be true by actual inspection of a flower in 
its different stao;es of growth. 
When the filaments are combined into a single mass, the 
mass is said to be a brotherhood or an adelpliia : if there is 
one combination, as in Malva, they are monadelplious (Jig. 1 14.) ; 
if two, as in Fumaria or Pisum, diadelplwus ; if three, as in 
some Hypericums, triadelplious ; if several, as in Melaleuca, 
polgadelqdious (Jig. 112.). The tube formed by the union of 
the filaments in a monadelplious combination is called, by 
Mirbel, androphorum.
