which has the margins incurved; fibrillose to the base ; 
inner surface with numerous round pores, especially near the lacared 
margins; on the outer surface with semi-elliptical pores in rows 
on the ne a which pass over near the apex into large 
ne -ga 
eading aks elongated, acuminate at the apex, with the 
vcontieal cells very fibrose and porose. Branch-leaves very large, 
longly ovate, and with the upper sod distinctly squarrose (? always) ; 
pore-formation as in the stem-leav 
Chlorophyllose cells in eer broly trapezoid (up to 12 » wide) 
(rarely broadly-triangular), with the longer parallel side exposed 
on the inner surface of the tool generally free on both surfaces.

This species comes very near S, cymbifolium, but must, especi- 
ally on account of the ered trapezoid chlorophyllose cells, be held 
to be distinct. From S. degenerans, too, with which it agrees in the 
— = its chlorophyllose cells, it differs in the strongly fibrose 
d branch cortical cells, the wider and shorter hyaline cells 
of “the | shee leaves, and the quite different habit.
