Anthurium polyschistum appears to be nearest to the 
poorly understood A. eminens Schott. It differs, how- 
ever, in being a crawling epiphyte, not an ‘‘arborescent”’ 
plant, in having much smaller leaves, a much shorter 
petiole, a spadix only one-fifth as long, and in the color 
of the spathe. Anthurium polyschistum is, in general, a 
much weaker and smaller plant.
