The seeds of Hydrangea are described by many authors, as by the accurate Maxi- 

 moTHCz, as alate. The seed in its inner coat is a perfectly smooth ellipsoid; the. 

 outer coat is a loose long cylindric sack, in the middle of which the nucleus lies ; as the 

 seed ripens the empty ends of the sack wither and contract whence results a seed 

 * tailed at each end.'
