at the apex of each branch a very small capitulum with obtuse 
branches. Cortex of the branches with numerous fibrils and pores 
Spreading branches very thin, about 1-1 ong, tapering 
wards the apex, and either recurved or almost horizontal 
Leaves s more or less loosely placed, on 
he upper ones closely imbricate and with squarrose apex; from 
a narrower ba c dened to the middle and then narrowed to 
a shorter or longer, wide, obtuse, cucullate apex, as in S. cymbi- 
folium f. squarrosula ; in the upper part frequently with 2-5 rows of 
shorter and narrower chlorophyllose cells on the lateral margins, 
the apex also peng Sores formed of such cells alone. Hyaline 
cells remarkably narrow and long; the chlorophyllose cells, on the 
contrary, seen Pees the inner side, very wide, showing, as is the 
cells. Pores on the inner surface scattered; in the upper cell- 
ang 2%; towards the lateral MBG Nes generally more numerous and 
the middle of the cell-wall; on the entire outer surface with 
niches round pores in almost mor cell-angle. 
Chlorophyllose cells in section broadly isosceles-trapezoid, free on 
both surfaces, the wall generally strongly convex on the inner sur- 
face, slightly convex on the outer surface; lumen very wide, full of 
wider than high, approaching the ie aline cells in form me size, 
and, like these, are oe = a Robs surfaces.
