A. Pollinium still attached to the rostellum with the pollen-mass still lying in the clinandrum on the summit of the column.
B. Pollinium in the position which it first assumes from the elasticity of the pedicel.
C. Pollinium in the position ultimately assumed from the hygrometric movement.
The pedicel when freed suddenly bends into the form represented at B, and soon afterwards owing to the hygrometric contraction curls up into the odd figure shown at C. When placed in water it resumes the form represented at B.
