Dispersal of Herbaceous Angiosperms . 
If the Hawaian flora is really an ancient one, a conclusion to which all 
the facts at our command seem to point, and if it is truly representative of 
the flora of the tropics and sub-tropics of late Tertiary time, then we must 
admit that these ancient floras were composed overwhelmingly of woody 
plants. 
C. The Fiji Islands. 
The flora of Fiji is also predominantly woody, and an analysis of 
it (based on Seeman’s ‘ Flora which is doubtless far from complete but 
probably representative of the whole) is presented in the following table :

The ancient element of the flora here is almost entirely woody and 
nearly all the herbs are apparently of recent introduction, since so few 
of them are endemic. 
D. Tahiti . 
Data for a general analysis of the flora of Tahiti were not available, 
but its herbaceous percentage is doubtless much like that of the rest 
of Polynesia. There are four endemic dicotyledonous genera (Fitchia, 
Lepinia , Apetahia , and Sclerotheca), none of which possess herbaceous 
species. Fitchia approaches the Hawaian arborescent Compositae more 
closely than does any other Polynesian plant ; and Apetahia and Sclero- 
theca may be taken to represent the Hawaian tree-Lobelias. The most 
ancient element in the flora is entirely woody. 
E. Other Polynesian Islands. 
Detailed figures for other Polynesian islands are not at hand, save for 
an analysis of the flora of French Polynesia (Castillo). In this group, out 
of 308 native Dicotyledons, 79, or 23 per cent., are herbaceous. The 
indigenous flora of the other islands doubtless contains an approximately 
equal percentage of herbs. 
There are a large number of species which, although not endemic 
in any one island or group of islands, are nevertheless limited or nearly 
limited to Polynesia. Including such plants with those which are endemic 
to particular groups, there are thus endemic to Polynesia (exclusive of 
Hawaii) 32 genera and 452 species, jo of these species are herbs, or 2-2 
per cent., but none of these belong to the endemic genera. It is thus 
apparent that the element in its flora which Polynesia shares with the rest
