Plants delicate to robust, and in denser or looser, very soft 
tufts ; light brown or yellowish green; small forms uate! re- 
sembling S. molluscum, with ohaal it sometimes grows intermixed. 
Stem-cortex of 2-3 layers; cells of one-half the posi ae 
much wider than in the other, all thick-walled, but clearly differen- 
tiated all round from the pale or yevomes wood-cylinder. 
Stem-leaves small, up to 90 mm. long, and in the middle 57 mm 
almost equal width throughout; margin more or less inrolled. 
Hyaline cells rarely divided by an oblique cross wall; towards the 
lateral margin becoming regularly narrower and a icilor above 
shorter and wider, rhomboid and almost Avnet with stout fibrils ; 
on the inner surface with numerous large non-bordered pores, 
which are as wide as the hyaline cells, and a placed between the 
fibrils ; on the outer surface, on the contrary, with small, frequently 
incompletely bordered pores in the cell-angles in the upper half 
of the leaf only. 
Fascicles of 8-4 branches, which are either all similar, or only 
two are stronger and he ng, the other weaker branch being 
closely appressed 2 the stem. Leaves of the spreading branches

vermicular, non-fibrillose, or also with numerous fibrils; towards 
the apex on both sides sometimes with small membrane-gaps, 
Chlorophyllose cells in section isosceles-triangular ; the base of 
the triangle situated on the outer surface of the leaf; completely 
enclosed on the inner surface by the strongly convex hyaline cells,
