foiirteon of tlie Philii)i)iiie species considered by Gray, were not to be 

 found in tbe United States iSTational Herbai'inin, and but four of this 

 number were found elsewhere, one, Uoniytjrosa prrrollrli! ?)!., bein-i' 

 represented in the Gray Herbarimn, and three, Derris nlii/iRosa Bentli., 

 Sophora tonirtitom Linn., and Ruhiis rugosus 8111.. in the ('olunil)ia 

 University Herbarimn. Many of the species nientioned by Pickering, 

 such as Galinia, Cniciis, etc.. were not found, l)ut more careful search 

 may reveal them in some one of the above institutions, although it seems 

 evident that a considerable number of the Wilkes Expedition plants are 

 no longer extant. Only ninety-six species of Wilkes Expedition Phili})- 

 pine flowering plants were found in the United States National Museum 

 that wei-e not considered by Gray, and most of these represent common 

 ami widely distributed species. 



All lMiilipi)ine plants collected by the Wilkes Expedition that are 

 mentioned by Gray in his one published volume on the botany of the 

 Wilkes Expedition are enumerated in the list given below. Where no 

 doubt exists as to the correctness of his identification no connnent is 

 made. No attempt has been made to discuss the ferns in the present 

 paper, and it has not been thought worth while to enumerate the species 

 represented in the United States National Herbarium that Avere not 

 considered l)y (iray. The present paper will serve to clear up a number 

 of points in regard to the synonomy of Philippine species, and an 

 examination of the authentic specimens in the light of our present 

 knowledge of Philippine botany has enabled me to correct several errors 

 in identification on the part of Dr. Gray. 



The photographs of the four types here reproduced were supplied me 

 bv Dr. J. X. Pose, associate curator of the United States National Her- 

 l)arium, and arc here ])ublished with the consent of the Secretary of the 

 Smithsonian Inst itul ion.
