 ON THE BUOYANCY OF THE SEEDS OF EUPHORBIA AMYGDALOIDES AND 



E. SEGETALIS 



The seeds of both species have no proper buoyancy, and display no 

 structure in their testas suggesting it ; though, through the shrinking of the 

 nucleus, a temporary floating power may be acquired with less mature or 

 imperfect seeds. They support the general principle indicated for the 

 British species on page 29. 



NOTE 91 

 MR. E. KAY ROBINSON ON THE DISPERSAL OF ASTER TRIPOLIUM 



According to this naturalist, the seeds of this plant are eaten in winter 

 by snow-buntings on the English east coast. In reply to my query he tells 

 me that the " draggled fluff still containing seeds " might easily adhere to 

 birds (The Country-Side, Sept. 30, 1905).
