Table illustrating the Degree of Buoyancy of the Seeds and Fruits of Inland Fijian Plants

(Unless otherwise indicated, the seeds or fruits sink at once or in a day or two)

NOTE 5 (page [14]).
The Inland Fijian Plants possessing Buoyant Seeds or Fruits

They come under the following heads:

(a) Plants of the stream-border or the pond-side or of the inland swamp, e.g., Lindenia vitiensis and Hydrocotyle asiatica. The extension of the principle by which plants with buoyant seeds or fruits are located, not only at the sea-side but at the water-side generally, is here involved, as explained in [Chapter III.]

(b) Plants following the rule deduced by Schimper for Terminalia, that when a genus comprises several species possessing buoyant fruits, only those having fruits with the greatest floating power are found at the coast, the least buoyant plants occurring inland; examples, Calophyllum and Guettarda.

(c) Plants that like Ipomœa behave irregularly in respect to seed-buoyancy, a difference in behaviour often associated with varying stations both at the coast and inland.

(d) Plants with dehiscent buoyant capsular fruits, like Sterculia, where dehiscence takes place on the tree and the seeds have no buoyancy. Although the unopened fruit may float a long time, it does not in that condition come under the influence of the currents.
