Contributions to our Knowledge of the 

 Flora of Borneo.

In a previous paper on the Bornean flora* I briefly indicated 

 the striking differences between the relationships of the Philippine- 

 Moluccan floras on the one hand, and the Philippine-Bornean floras 

 on the other hand, describing forty-eight new species of Bornean 

 plants and one new genus, and crediting a number of other species 

 previously described by other authors to Borneo. The present 

 paper is in the nature of a continuation of the first one published; 

 and in it I have described thirty-nine new species and credited 

 about twenty-five additional ones to Borneo for the first time. The 

 types of the new species proposed are preserved in the herbarium of 

 the Bureau of Science, Manila, P. I. 



In the present paper new species are described in the following 

 families: Gramineae, Cyperaceae, Bosaceae, Leguminosae, Butaceae, 

 Meliaceae, Euphorbiaceae, Vitaceae-, Elaeocarpaceae, Tiliaceae. 

 Thymelaeaceae, Ericaceae, Symplocaceae, Verbenaceae, and Bubi- 

 aceae. Perhaps the one addition to the Bornean flora of greatest 

 interest is the discovery of a representative of the genus Faraday a 

 in British North Borneo, this characteristic genus having been 

 known previously only from New Guinea, north-eastern Aus- 

 tralia, and Polynesia. To the rather small list of species known 

 only from Borneo and the Philippines are added Artocarpus odora- 

 tissima Blanco, Knema glomerata Merr., Ellipanthus mindanaensis 

 Merr., Greivia stylocarpa Warb. (a variety in Borneo), and Sym- 

 plocos phanerophlebia Merr. Genera new to Borneo are Scleropy- 

 rum, Elaeodendron, Columbia, and Faradaya. The new generic 

 name Iloseanthus is proposed for the form that Eidley described 

 as Hosea, on account of the previous use of the name Tlosea by 

 Dennstaedt for a different group of plants.
