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



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



This extremely rare species of Hibiscus, which Mr. Rock fouiul firowing 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, .^ince it grows under arid and rather severe conditions it may be found 

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

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

 mentals. (Photographed by J. F. Rock, Oahu, Hawaii, March, 1918; P27(X):JFS.)
