flower opens a curvature ensues at the base of the pedicels by 
and the inflorescence is finally held erect. Meanwhile the pedicels 
exhibit a second series of independent movements. These struc- 
tures acquire < sensitiveness to gravity by which they tend to 
curve upward independently. fter the scape has assumed a 
final erect position the pedicels which as has just been described, 
tended to assume an upright position, now take on separate and 
individual positions by which each is separated from its neighbors 
equidistantly, in which uae aed remain until fee has

Strepto leas Rhexti bears a number of striking flowers each on 
its eae uncle which is curved in such manner that the un- 
stamens and pistils mature the opened corollas held in a horizon- 
tal position until fertilization is accomplished, when the apical 
portion of the peduncle again takes up a motion by which its cur- 
vature is straightened until the capsule is held in an approximately 
erect position, The signal or stimulus for each of these motions 
deposited on the pistil, and presumably the growing tubes from 
the germination of the pollen have reached the egg cell. The
