In the bud both stamens and styles have an upright position,

_ out, take a horizontal position and soon begin to recurve. The 
_ anthers at the same time become first vertical, 2. é., at right angles

_ the filaments, and when these have recurved they appear some-

i In this condition they are prepared to leave pollen on the backs of

ers are pressed against the column, in which shape they 
look decidedly as if they had at first been extorse (Fig. 4 a). In 
shape they are effete, since the pollen must fall on the back
