MATERIALS FOR A FLORA OF FORMOSA. ig 
northern hemisphere. Another case of novelty is the addition of 
two families to the present flora. They are Hernandiacee and 
Myristicee. 
The materials upon which this work is based are, in oreater 
part, the collections made by the Governmental Botanical Survey, 
supervised by Mr. 'T. Kawaxamt, during 1906-1909. I have also 
referred to a small set of specimens of Loo-chooan plants, collected 
by Mr. G. Naxawara, a few dubious specimens from the Loo- 
choo and Bonin islands, preserved in the Herbarium at Tokyo, 
and small collections of Formosan plants sent by Mr. 8S. Nagasawa 
and the late N. Kontsut. 
The present work was, in great part, carried out by myself 
in the Herbarium at Kew. A few families were examined by 
the staff of the same laboratory. Of the staff, 1 may mention 
Dr. O. Starr for doubtful families, Mr. E. N. Brown for Ascle- 
piadex and Aroidexw, Mr. R. A. Rotre for Umbellifere and 
some Orchids. 
In conclusion, I must tender my hearty thanks to Prof. 
J. Marsumura for his encouragement during the present work. I 
also wish to express my sincere gratitude to Mr. K. Osurma, 
Ex-Chief of Civil Government of Formosa, by whose graciousness 
extended towards myself, I was able to visit the principal herbaria of 
the West. To Lieut. Col. D. Prary, Director of the Royal Botanic 
Gardens, Kew; to Monsieur le Prof. Dr. H. Lecomre, Directeur 
de la Galerie de Botanique du Muséum a Paris; to Herrn Prof. 
Dr. A. Enater, Direktor des Kgl. Botanischen Gartens und Mu- 
seums zu Dahlem, and to Monsieur le Prof. Dr. A. A. FIscHER 
yon WaLpuEem, Directeur du Jardin Impérial de Botanique 4 St. 
Pétersbourg, I am also greatly indebted for permission to work 
in their herbaria. My very cordial thanks are also due to Dr.
