The earliest specific name of this species, /¢piden- 
drum variegatum Hook., is not tenable on account of the 
earlier use of the combination by Swartz in 1788 and by 
Koenig in 1791. The next name chronologically is 2. 
coriaceum Parker apud Hooker, but this again is ante- 
dated by the combination /.cortaceum Poiret made in 
1810. The third name applied to this species was 47. cras- 
silabium Poepp. & Endl. and this name, being the valid 
one, should replace Hooker’s H.variegatum.
