pipe line, elevation 4,000 feet, flowering Oct. i, 1916, A. S. Hitchcock no. 
14913, in U. S. National Herbarium. 
Hawaii: Hilo, Hillebrand, not in herb. Berlin. 
A distinct variety and almost of specific value. Comes, however, close 
to the species save in the subulate calycine lobes. The whole plant is very 
delicate and membranous. It grows in dense shade along streams on West 
Maui in company with Gunnera petaloidea, Kadua, Schiedea diffusa, etc. 
The specimen collected by A. S. Hitchcock near Olinda has small ovate leaves 
but agrees other vvise with the type.
