210 MISS L. S. GIBBS: A CONTRIBUTION TO 
At Tavua large patches of Acrostichum aureum with Mangroves preceded 
the Mangrove swamp, which shelved in shallow water nearly to the reef, 
necessitating a long row out by boat to piek up the coasting steamer. This 
formation seemed to be increasing its area. 
These notes being limited to one collection, and that including only the 
species in flower at a certain season in one particular locality, are necessarily 
very scanty, forming the barest outline of prevailing conditions. 
In a eountry whose flora is only known from sporadic collections, it is difficult 
to estimate the correct terms. Trees, for example, like the Vuga and Vure, 
may flower when only one foot high, and as the clearings are the best collecting- 
grounds, it is difficult to decide what remains a shrub or grows into a tree. 
In some cases help is derived from other collections, but in others, with plants 
like Acronychia petiolaris, Hedycarya dorstenioides, Cyrtandra glabrata and 
С. involucrata, Casearia Richii, Psychotria platycocca, and Claoxylon echino- 
spermum, which were always found as shrubs in clearings fringing the deeper 
parts of the high forests, it would be impossible to say whether they were 
part of the forest flora or belonged to a different association. As I have 
indicated before, it would require a long series of observations and a good 
local knowledge of floral conditions to decide which species will be eventually 
crowded out and which persist as forest-trees.
