(From the Botanical Section of the Biological Laboratory, Bureau of Science,

Ames, Oakes. Orchidaceae : Illustrations and Studies of the Family Orcliidaceae, 
issuing from the Ames Botanical Laboratory, North Easton, Massachusetts, 
fascicle 1 (1905) pp. 1-156; fascicle 2 (1908) pp. 1-288. 
Of fascicle one, pages 1 to 13 and plates 1 to 3 treat of Philippine orchids, 
while pages 63 to 107 are occupied by a descriptive list of orchidaceous 
plants collected in the Philippines by botanists of the United States Govern- 
ment, about 60 species being considered, many of them described for the first 
time. Fascicle 2, pages 1 to 6 and plates 17 to 19 treat of Philippine 
orchids, and on plates 21 to 24 eighteen species of Philippine Dendrochilum 
are figured. The greater part of this fascicle is taken up by a paper 
entitled “Studies in the Orchid Flora of the Philippines,” pages 17 to 257, 
with many figures, about 235 species being considered. This work is by far 
the most important one that has ever been issued on the Philippine represent- 
atives of this family.

casuarinoides Spring; Selaginella auriculata Spring, S. coinmersoniana Spring, 
S. plumosa Baker, S. barbata Spring, S. cumingiami Spring, S. philippina

willdenovii Baker, S. caulescens Spring, S. pennula Spring, S. pteryphyllos 
Spring, S. intertext a- Spring, S. myosuroides Spring; Marsilea minuta Linn., 
and by inference other species of Lycopodium and Selaginella, also Psilotum 
and Asolla. 
Bailey, J. W„ & Harvey, W. H. Algae in Rept. Wilkes U. S. Exploring Expedi- 
tion 17 (1862) 155-192. 
Six species of algae are recorded from the Philippines, one of Which is 
described as new. Following the paper on algae, the Diatomaceae and other 
microscopic forms are enumerated. For Diatomaceae see Harvey & Bailey 
below. 
Benjamin, Ludwig. Neue Gattungen und Arten der Utricularieen nebst einer 
neuen Entheilung der Gattung Utricularia. (Linnaea 20 (1847) pp. 299- 
320.) 
Three species are described from Cuming’s Philippine distribution, Utricu- 
laria brevicaulis, U. rosulata, and U. het'erosepala. The first however was 
based on Cuming 2289, which was collected in Malacca, not in the Philippines.
