BY FATHER MORICE VANOVERBERGH, II 
By E. D. Merrill 1 
( From the Botanical Section of the Biological Laboratory, 
Bureau of Science, Manila, P. I.) 
The first paper of this series was published in June, 1912, 2 and 
essentially the present contribution is like the first, consisting 
chiefly of the descriptions of new species of flowering plants 
that have been detected in the material submitted by Father 
Vanoverbergh for identification within the past two years. 
Seventeen species are proposed as new, in the genera Adel- 
meria, Calophyllum, Croton, Dysoxylum, Flacourtia, Illigera, 
Leea, Lorantkus, Psychotria, Pygeum, Ranunculus, Rabus, 
Saurauia, Schefflera, Sophora, and Trichosanthes. Polygala 
longifolia Poir. is for the first time credited to the Philippines.
