According to Ilillebrand and Wawra a truly superb and royal plant. The 

 writer has not met with this specie.s ; the lower .slopes of Xiu and Wailupe, the 

 region where this plant once flourished, is now grazing land, and otherwise more 

 or less barren The writer fears that this magnificent plant has. like other Ha- 

 waiian LohdioicJrae of the lower elevations, suceuml)ed to the ravages of cattle. 



Ci/iiiud rifiiiui differs from Cfiiuua siipirlm in ac>\te or acuminate leaves, the 

 much shorter [leihuicles. which are somewhat louLicr than the iietiole, and the 

 shorter linear-s])athulate bracts.
