Phalaenopsis aphrodite Reichb. f., Dicksonia smithii Hook., Davallia 
cumingii Hook., and Polypodium meyenianum Schott. This list of but 
20 species is very small when compared with the list of over 50 known 
exclusively from Celebes and the Philippines, 5 the Celebes-Philippine 
list including two genera confined to the two groups, Wallaceodendron. 
monotypic, and It einwardtiodendro n, two species; moreover the flora of 
Formosa is infinitely better known than is that of Celebes. Three 
sjiecies, Boea swinlioii Hance, Mallotus playfairii Hemsl., and Gaultheria 
borncensis Stapf, have the peculiar distribution of from Formosa to 
Luzon and northern Borneo. 
A certain number of species extend from Japan to southern China, 
Formosa and Luzon, and another group, Himalayan types, extends from 
the Himalayan region eastward to the mountains of Formosa and Luzon, 
and sometimes to Japan, but these can not be considered as throwing 
much light on the individual relationships of the floras of Luzon and 
Formosa, as, at least the Himalayan types, might have reached the two 
islands independently, and at entirely different periods. 
The collections adds to our knowledge of the Philippine flora two 
genera, Erythraea, represented by the introduced E. spicata (L.) Pers., 
and Phoenix, represented by a new variety of P. hanceana Naud., and 
the following 12 species, previously described from extra-Philippine 
regions: Iscliaemum ciliare Retz., Setaria verticilldta (L.) Beauv., Lilium 
longifiorum Thunb., Podocarpus polyslachyus R. Br., Elatostema platy- 
phyllum Forst., Chenopodium acuminatum Willd., Pueraria thunbergiana 
(S. & Z.) Benth., Lysimachia mauritiana Lam., Ipomoea stolonifera 
(Cyrilli) Poir., Glerodendron trichotomum Thunb., and Gynura elliptica 
Yabe & Hayata, while 24 species have been described as new, 15 in the 
present paper, 9 in preceding ones. 
The material on which the present paper was based, was collected, in 
part, in June, 1907, by Major E. A. Mearns, surgeon, United States 
Army, on the Islands of Batan and Fuga, but mostly by Mr. Eugenio 
Fenix of this Bureau, who in company with Mr. B. C. McGregor, also 
of this Bureau, spent the greater part of June and July on the islands 
of Batan, Sabtan, Babuyan, and Camiguin, a very few specimens being 
collected on Y’Arni Island. For the opportunity of having these col- 
lections made, this Bureau is indebted to Major-General Leonard Wood, 
and to the Honorable Dean C. Worcester, Secretary of the Interior of 
the Philippine Government. 
The ferns enumerated below were identified by Dr. E. B. Copeland, of 
the Bureau of Education, Manila, and the palms by Dr. 0. Beccari, 
Florence, Italy ; all the other identifications, unless otherwise stated, were 
made by the author.
