The genus Philodendron contains, according to Engler’s 
monograph published in 1879, no less than 120 species, 
and if the little attention paid by collectors to these gigantic 
aroids, and the difficulty of preserving specimens of them 
be taken into account, it will be obvious that this number 
must represent but a small fraction of what exist. The 
genus abounds in the forests of tropical America and its 
islands, and like orchids, is better known from cultivated 
specimens than from descriptions made in their native 
habitats, or from herbarium specimens. Most of the known 
species have indeed been described by the late Dr. Schott, 
of the Imperial Gardens of Schoenbrunn (Vienna), who had 
imported many himself from the forests of Brazil, where 
they were a favourite study of his; and the long ranges of 
tall houses festooned from end to end with magnificent 
specimens of climbing species, on poles, trellises, and rafters, 
formed one of the most wonderful horticultural exhibitions
