ACKNOWLEDGEMENTS. 
Extensive accounts of the alcohol and sugar possibilities of the more 
prominent species of palms have been given by Gibbs (The alcohol industry 
of the Philippine Islands, parts I, IJ, and III. Philippine Journal of ° 
Science, Vol. 6, 1911, and Vol. 7, 1912); while hats made from palm 
fibers have been discussed at length by Miller and Robinson (Miller: Phil- 
ippine Hats. Bureau of Education Bulletin No. 35, 1910. Robinson: Phil- 
ippine Hats. Philippine Journal of Science, Vol. 6, 1911). Arnold (Rat- 
tan supply of the Philippines, Special Agents Series, No. 95, Bureau of 
Foreign and Domestic Commerce, Washington) has written a long discussion 
of the rattan supply. These sources have been drawn on extensively in 
the preparation of the present paper. The systematic consideration of 
Philippine palms has been much simplified by the appearance of a recent 
paper by Beccari (Philippine Palms. Philippine Journal of Science, Vol. 
14, 1919). The keys to, or rather the conspecti of, the species of the 
various genera are taken from that paper, with only slight changes in 
nomenclature.
