4 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 60 



KOKIA LANCEOLATA Lewton, new species 

 Gossypium drynarioides var. /3 Hilleb. Fl. H. I., 1888, p. 51. 



Under G. drynarioides variety /?, Hillebrand mentions two trees 

 having- lanceolate involucral bracts which are only one-half as wide 

 as long. These were found on the hills of Makaku and Koko Head, 

 at the eastern end of Oahu. Mr. J. F. Rock, after a careful search, 

 failed to discover a single tree now growing on the Island of Oahu. 



No specimen, known definitely to have been collected in Oahu, has 

 been seen by the writer, but a study of Hillebrand's narrow-bracted 

 specimen in the Gray Herbarium, referred to under K. drynarioides, 

 which was without locality, has convinced the writer that Hillebrand's 

 variety /? should be considered as a distinct species. 



This view is taken ( 1) because in the variety as described by Hille- 

 brand, and in the narrow-bracted specimen collected by him, the 

 involucral bracts are but one-half as wide as long, or less, whereas, in 

 the four specimens of K. drynarioides examined these parts are as 

 wide as long, or wider; and (2) on account of the restriction of the 

 variety to another island of the Hawaiian group, in keeping with the 

 very limited distribution on certain islands of many Hawaiian plants 

 and animals.
