470 THE JOURNAL OF BOTANY 
narrow-trapezoid or almost spindle-shaped; distinctly excentric, 
with the wall usually of equal thickness all round, or rarely some- 
hat thickened on the inner surface of the leaf; enclosed on the 
outer surface by the strongly convex hyaline cells, or free as on the 
inner surface ; hyaline cells never papillose. 
Stem-leaves large, lingulate-spatulate, 1°5-3:1 (mean 2:1) mm. 
long, rarely twice as long as wide, generally the width about two- 
thirds the length. Rarely non-fibrillose or with a few delicate 
fibrils, generally with numerous strong fibrils throughout the entire 
leaf, and with a few to very numerous pores. Hyaline cells generally 
non-septate, but not rarely, and especially in the lower half, here 
and there divided. Border widest at the rounded apex, vanishing 
more or less towards the base. 
Dioicous; the male plant less robust, the antheridium-bearing 
branches short and thick, olive-green. Inner perichetial leaves 
the upper half resembling in structure the stem-leaves. Spores 
with di y aracter to be chiefly relied upon for dis 
tinguishing the species in the Cymbifolium section is the position 
m of the chlorophyllose cells as a section from 
the middle part of the branch-leaves. Purple or brown forms of 
S. cymbifolium would appear to be rare in this country. 
The varieties are based upon the colour of the tufts :— 
1) Var. carneum Warnst. in Verh. Bot. Ver. d. Prov. Brandenb.

whitish below.
