This singular plant is the second and only other species 
of the genus, the type of which, A. vulgare, was figured at 
Plate 6023 of this work. From this latter A. proboscideum 
differs so remarkably in the creeping rootstock (in contrast 
to the tuberous one of the type) and in the prodigious 
proboscidiform elongation of the spathe (which is truncate 
nA. vulgare), that it is remarkable that Schott, in his 
multiplication of the genera of the Order, did not separate 
the two generically. Schott is, however, one of the few 
of the notorious multipliers of genera who invariably 
founded these on definite, though too trivial characters, and 
his works on Aroidew will always maintain their high 
character for their accuracy, and for the singularly sagacious 
views they display of the affinities of the genera of this 
Order, which is one of the most difficult to analyze from 
dried specimens, and difficult to classify when analyzed, of 
JULY Ist, 1882.
