The style of the pistils of the disk in this plant, though 
these are fertile, appears to be elastic, and endowed with the 
faculty we have ascribed to that of the barren pistils in Arc- 
TOTIS, viz. of raising and lowering the stigma by alternate ex~- 
tension and contraction; but it does not seem in this instance 
combined with the irritability evinced in the former, by spon 
taneous motion responsive to the excitement of the touch, 
and which may in fact be confined to the style of those 
pistils, which are destined for mere auxiliaries in the func- 
tions of the stamens, but are ineffective in their proper ca~. 
pacity. |
