Iscuarum Pyrami? Schott, Prodr. Syst. Aroid. p. 66. 
Schott is the great authority for the genera of Aroideous 
plants, for no one has studied them with more care, nor figured 
and described them more accurately ; but it must be confessea 
that both the species and genera seem to us to be needlessly mul- 
tiplied. The genus of which Schott quotes Blume as the author, 
is in reality only a section of Biarum with Blume, and all the 
characters the latter attributes to this section are “Orzenfalia SivE 
Iscuara.” ‘Ten species are described by Schott, mostly of Syrian 
JULY Ist, 1862.
