not only the rich Philippine collections of 'the Bureau of Science, 
but also the extensive series of specimens from tropical Asia, 
Malaya, and Polynesia, belonging to that institution, including 
a nearly complete set of Volken’s Caroline Islands plants. The 
Palmae have been examined by Beccari, the Pandanaceae by 
Martelli, some of the Cyperaceae by Kukenthal, the Musci by 
Brotherus, the Hepaticae by Stephani, the Piper aceae by DeCan- 
dolle, and the Orchidaceae by Ames. In a few other cases I 
have received aid in the identification of certain specimens, this 
assistance being acknowledged in the text under the individual 
species. The enumeration of the Fungi is the work of Mr. Paul 
W. Graff of the Bureau of Science. Dr. E. B. Copeland has 
named some of the ferns. 
The first and most complete set of the botanical material from 
Guam is deposited in the herbarium of the Bureau of Science, 
and a nearly complete set has been deposited in the office of the 
Guam Experiment Station. The remaining duplicates have been 
distributed to various specialists and to institutions with which 
the Bureau of Science is in exchange relations. In the following 
enumeration the material secured through the native collector 
employed by the Guam Experiment Station is indicated as G. E. 
S., followed by the number of the collection. The recent collec- 
tions have yielded a total of about forty-five new species, and one 
new genus. 
While engaged in reading the proof on this paper I received, 
through the kind offices of Mr. W. R. Maxon of the U. S. National 
Museum, and of Mr. W. E. Safford, 162 additional specimens of 
Guam plants for study. This material was collected in Guam by 
Mr. Safford, by Mr. Alvin Seale, and by Mr. H. L. W. Costenoble. 
This collection adds a few genera and species to the list I had 
prepared for publication, and these additions have been included 
in the present paper. 
ENUMERATION OF THE SPECIES 
THALLOPHYTES 
FUNGI 
(By P. W. Graff) 
The few fungi known from Guam have been gathered only 
incidentally by collectors of other plants. The chief collection, 
and perhaps the only one, previously reported, was that made 
by Gaudichaud in 1819. Safford gives the list as follows : Auri- 
cularia auricula- judae (L.) Schrot., Fomes scabrosus (Pers.) 
Fr., Polypous kamphoeveneri Fr. ( Polyporus mariannus Pers.).
