The Babuyanes group consists of about nine islands, the largest of 
which are Babuyan, Calayan, Dalupiri, Fuga, and Camiguin. Babuyan 
has an approximate area of 38 square miles, its highest altitude being 
about 960 m. Dalupiri is a low island for its greater part covered with 
grass-lands, its area being about 20 square miles. Fuga is also low, 
with an area of about 27 square miles, with few trees, and these mostly 
near the coast, the interior being covered by grass-lands. Calayan is 
slightly larger than Fuga, with a moderately high central range of hills, 
covered with heavy forest with occasional patches of cogon grass. Ca- 
miguin is the largest island of the two groups, its area being given as 
about 60 square miles, and is rather rough and densely forested, its two 
highest peaks being respectively about 827 and 735 m in altitude. Some 
of the information regarding Fuga and Calayan was taken from Mc- 
Gregor. 2 Areas of the different islands was taken from the Gazetteer 
of the Philippine Islands. The nomenclature of some of these islands 
is somewhat confusing, and care should be taken not to confound 
Camiguin Island of the Babuyanes group with Camiguin Island off the 
north coast of Mindanao, the latter being the Camiguin visited by the 
Challenger Expedition, while Batan Island of the Batanes group should 
not be confused with Batan Island off the east coast of Albay Province, 
southern Luzon, nor with Bataan Province of central Luzon. 
In the following paper about 415 species are considered, but of the 
flowering plants collected, a few species of Zingiberacece, and about 10 
species of OrcJiidacece , are not included, the material not being determined 
at this time. Considerable collections of fungi, lichens, mosses and 
scale-mosses were made, but no attempt has been made to include these. 
The collection as a whole has shown the striking affinity of the flora 
of both groups to that of Luzon and the Philippines in general, and the 
comparatively slight relationship to that of Formosa. No less than 15 
species, enumerated in the present paper, or about 28 per cent of the 
total, are at present known only from the Philippines, giving a high 
percentage of endemism, while representatives of the following list of 
42 genera, all characteristic of the Philippine and Malay flora in general, 
are found in the two groups, but not as yet in Formosa, and represent- 
atives of but 10 of these have been found in southern China: Casnarina, 
Pipturus, Leucosyke, Tinospora, Limacia, Anamirta, Talauma, Phaean- 
thus, Polyalthia, Myristica , Knema, Intsia, Wallaceodendron , Ptero- 
carpus, M eilicope, Lunasia, Micromelum, Chiso chiton, Cyclostemon, Cleis- 
tanthus , Claoxylon, Homalanthus , Semecarpus , Turpinia, Gonocaryum, 
Ellatostachys , Pometia, Thespesia , Dillenia, Adenia, Medinilla, Boer- 
lagiodcndron, Aegiceras, Maba , Fcigraea, Geniostoma, Cyrtandra , Tri- 
chosanthes , Argostemma, Sarcocephalus, V illaria, and Guettarda.
