Compared witli a Japanese sjiecimen in tlie Tokyo lierbarium. Our plaut 

 accords tolerably well with the original description of Miquel. Leaves of tlie 

 species have no blade, but petiole broadened like a i)hyIIode. It is, to some 

 extent, comparable witli Saffittaria sagittifolia and may T)e regarderl as a variety 

 of the latter. lu my opinion, however, it is more reasonable to regard our plant 

 as specifically distinct from S. sagittifolia, as this form wanting leaf-blades is 

 pretty constant and is always fonnd to have sessile female flowcrs.
