The third part is devoted to general conclusions and a summary
of the studies. This is followed by an alphabetically arranged list
of most of the spontaneous plants found on the peninsula of Carc-ranh.
About kQ species remained to be identified at the National Museum of
Natural History. A list of 26 references, mostly French, is included.
This is followed by a series of 18 tables, showing the chemical
analysis of sand specimens; ratio of association of Spinifex littoreus
and Vitex trifolia var. simplicifolia with local dominance of Pandanua
reversispiralis at the northern end of the peninsula; and other associations
in the area under study, including a conrparison between the
floristic composition of the mangrove forest of Caro-ranh with that of
Ca-Mau and Cap St. Jacques.

This paper presents the results of the preliminary ecological
study on the vegetation of Thailand, especially of the northwestern
regions, carried out by the Osaka City University, Bioological Expedition
to Southeast Asia.
The field study was made during the four months of travel through
Thailand during the dry season of 1957-58. Obser/ations were made
while traveling, chiefly by automobile, from Bangkok to the northwestern
boundary of Thailand, several brief excursions to the northwest
highlands, including the ascent of mountain Inthanon, the highest
