A New and Brilliant Hawaiian Hibiscus. (Hibiscus brackenridgei A. 

 Gray. S. P. I. No. 50693.) 



This extremely rare species of Hibiscus, which Mr. Rock found growing among the stones at the base 

 of a cliff on the windward side of the island of Oahu, is a thing of rare beauty when covered with 

 its large yellow flowers. Since it grows imder arid and rather severe conditions it may be foimd 

 useful as" an ornamental plant in some parts of tropical America which, because of imfavorable 

 climate and soil, are not weU suited to the cultivation of many of the common tropical orna- 

 mentals. (Photographed by J. F. Rock, Oahu, Hawaii, March," 1918: P27003FS.)
