CHAPTER IV.
THE CIRCUMNUTATING MOVEMENTS OF THE SEVERAL PARTS OF MATURE PLANTS.
Circumnutation of stems: concluding remarks on--Circumnutation of stolons:
aid thus afforded in winding amongst the stems of surrounding plants--
Circumnutation of flower-stems--Circumnutation of Dicotyledonous leaves--
Singular oscillatory movement of leaves of Dionaea--Leaves of Cannabis sink
at night--Leaves of Gymnosperms--Of Monocotyledons--Cryptogams--Concluding
remarks on the circumnutation of leaves; generally rise in the evening and
sink in the morning...201-262

CHAPTER V.
MODIFIED CIRCUMNUTATION: CLIMBING PLANTS; EPINASTIC AND HYPONASTIC
MOVEMENTS.
Circumnutation modified through innate causes or through the action of
external conditions--Innate causes--Climbing plants; similarity of their
movements with those of ordinary plants; increased amplitude; occasional
points of difference--Epinastic growth of young leaves--Hyponastic growth
of the hypocotyls and epicotyls of seedlings--Hooked tips of climbing and
other plants due to modified circumnutation--Ampelopsis tricuspidata--
Smithia Pfundii--Straightening of the tip due to hyponasty--Epinastic
growth and circumnutation of the flower-peduncles of Trifolium repens and
Oxalis carnosa.
