178 PHANEROGAMIA. 



having very short-pedicelled and whitish flowers, with the petals 

 velvety-pubescent externally, and an involucel rather longer than the 

 calyx. Noticing these points when I long ago examined a collection 

 of Sandwich Island plants, made by the late Rev. John Diell, I com- 

 municated a specimen to the herbarium of Sir William Hooker, under 

 the name of Hibiscus Arnottianus, which is here adopted. It is a very 

 showy species, apparently of the section Cremontia; although the 

 petals are expanded in anthesis. According to Hooker and Arnott, 

 the seeds are clothed with fulvous hairs. None of the specimens in 

 the collection of the Expedition show the fruit; but the ovules, after 

 the corolla has fallen, are glabrous.
