By E. D. Merrill. 



(From the Botamcal Section of the Biological Lahoratory, Bureau of Science, 



Manila, P. I.) 



The following- paper is largely composed of the descriptions of about 

 100 new species of Philippine plants, that have been worked out from 

 time to time during tlie past year. In the paper will also be found the 

 descriptions of four proposed new genera, Astrocalyx and Cephalomedi- 

 niUa of the Mdastoinataceae, Gurraniodendron of the Saxifragaceae, and 

 Pygmacoprcmna of the Verhenarcae. A number of species previously de- 

 scribed by various authors are here recorded from the Philippines for 

 tlie first time, wliile sevei'al previously considered Philippine forms are 

 admitted for the purpose of discussion, additional data being available. 

 Following the rules of priority in nomenclature, a few new combinations 

 have been made. 



GRAMINE^. 



ANDROPOGON Linn. 



Andropogon citratus DC. Cat. Hort. Monsp. (1813) 78. 



Cf/mbopogon citratus Stapf in Kew Bull. (1906) 322, 357, cum lamina. 



Andropogon schoenanthus Blanco Fl. Filip. (1837) 39, ed. 2 (1845) 27, ed. 3, 

 1 (1877) 50; Merr. in Philip. Journ. Sci. 1 (1906) Suppl. 339, non Linn. 



This species is commonly cultivated in the Philippines, although not on a 

 commercial scale. I have never seen it in flower, but chemical analysis of the 

 oil extracted from it shows tho species to be Andropogon citratus DC, and not 

 A. schoenanthus Linn.
