Cohesion of two or more segments of the perianth 
is frequently associated with displacements of this 
nature: thus, in a flower of Dendrobiwn nobile, a 
diagram of which is given at fig. 48, the uppermost sepal 
was coherent with one of the lateral ones, and at the 
same time diminished in size, and, as it were, dragged 
out of position. All the other organs of the flower are
