The Babuyanes group consists of about nine islands, the largest of 

 which are Babuyan, Calajan, 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 30 square miles. Fuga is also low, 

 with an area of about -S? 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.^ 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 ]\Iindanao, 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 Zingiheracecc, and about 10 

 species of OrcliidacecE, are not included, the material not being determined 

 at this time. Consideral)Ie 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 al)Out 28 per cent of the 

 total, are at present known only from the Philippines, giving a high 

 percentage of endemism, while re])resentatives of the following list of 

 42 genera, all characteristic of the P]iili])pine 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: Casuarina, 

 Pipturus, Leucosylxc, Tinospora. Liinacia. Ananiirla. Talauma. Phacan- 

 iJiu.s, Polyalthia, Myristica, Ktunna, fnlsin. W'cJhurudcndron. Ptero- 

 carpus, Mdicope, Lunasia, Micromchim, Chisochitoii. Cydostcmon. Clcis- 

 tanthus, Claoxylon, Homalanlhuft, Semecavpns. Turpinia. Gonoraryum, 

 Ellatostacliys, Ponieiia, Tlicspe.'tia. DUlcnia, Adenia. McdiniUa. Boer-
