in a thick coat of yellow powder, to afford it from this new 
position the means of an access necessary to the otherwise 
unprovided stigmas of the surrounding ray: a task to 
which the proper organ is evidently here incompetent. By 
and by the same are seen to retreat gradually within the 
cavity of the now empty anthers. When recently emerged 
and charged with pollen, they bend and incline themselves 
with a lively motion on the slightest touch, but always in 
the direction whence the impulse came; and in so doing 
necessarily part with a portion of the pollen that covers 
them. And as the honeyed liquid which attracts the insect 
to the flower is deposited in the ray that surrounds the 
disk, the impulse will be the more certainly given by that 
mean, probably the only one, from the side towards which 
it is requisite that the pollen should be carried. The style, 
by the extension and contraction of which the stigma is 
made to advance and withdraw, seems to consist of a sub- 
stance resembling elastic gum (Caoutchouc), and may be 
repeatedly drawn out to a considerable extent like that, 
contracting to its former dimensions when left to itself 
with the same elastic force. }

dissection, seems not to have been elsewhere noticéd; at 
Jeast not in any work known to us.

a A vertical section, showing the bristly alveolated receptacle, deprived 
of its florets. & A fertile floret of the ray, with the germen crowned by a 
double paleaceous pappus, enveloping the tube of the floret, above which 
the stigmas are elevated, _c A barren floret of the disk, in which the stigma 
is shown in the elevation it acquires to aid in the distribution of the pollen 
among the florets of the ray: magnif.
