found described in Note 22. Those tested were Cassytba (iliformis, 

 Cerbera Odollam, Ipomea pes caprae, Morinda citrifolia, Premna tahitensis, 

 Scsevola Kcenigii, and Tacca pinnatifida. In all but Cerbera Odollam, 

 where I contented myself with establishing that the fruits floated bu< 

 antly in sea-water, the experiments were prolonged for many weeks and 

 often for several months ; and in some cases, as with Ipomea pes caprse, three 

 or four experiments were made on seeds from different inland locali'.' 

 The result was to establish in all cases that the floating power- wer< 

 great with the inland as with the coast plants of the same spedfefi : nor 

 could any structural difference of importance be noticed. It should D 

 observed that there is every reason to believe that the "talasinga " plains 

 of Fiji have been occupied by the intruding beach-plants for many ag

 in Chapter XII., three non-adaptive and five adaptive, we get a propori:

On the Modes of Dispersal of the Genus Brackenridgj \. 



Seed-vessels of this genus found afloat in the New Guinea drift an 

 scribed by Mr. Hemsley as having two curved cavities crossing each other, 

 one containing a seed, the other empty. " This empty cavity," it is stated, 

 "gives the fruit its buoyancy" (Bot. Chall. Exped., iii., 289 : plate 54)-
