posite, one at each side of the frond. Colour faded. The 
structure of the stem is denser than is usual in the genus, 
the cellules of the axis being smaller, and those of the 
periphery more filamentously disposed than in the typical 
species.

Our specimens are very imperfect. They consist of por- 
tions of the stem, 3-4 inches long. The colour has faded.
