aa -cortex generally apparently absent, not or scarcely differen- 
tiated from the wood-cylinder 
with obtuse somewhat fimbriate apex; border widened below. 
Hyaline cells non- tee 3 generally non-fibrillose, more rarely 
with fibrils towards the 
ranch-leaves small, but ‘Tittle over 1 mm. long and ‘34-4 mm. 
broad, narrowly lanceolate, border narrow, margin inrolled onl 
tinctly undulate. Leaves of the peeadiag Bakes on the inner 
surface with numerous, round, non-ringed pores in the cell-angles 
from the apex to the base; on the outer surface towards the apex 
with small strongly ringed or in part incompletely en re Seley in 
the cell-angles or on the commissures, in the basal ha r the 
lateral margins with large pores in the upper cell-angles. " eateb 
of the pendent branches on the outer surface in the apical half 
wit dsall pores in the lateral and lower cell-angles, and with large 
membrane-gaps in the upper cell-angles which frequently are im- 
mediately above the pores on the inner surface, so that complete 
perforation of the leaf results. Perigonial bracts differentiated, 
ovate-lanceolate to oblong-lanceolate, from a narrower base widene 
to the middle, and then produced into a short, truncate, and toothed 
apex; in the abil half light brown, and here generally non-fibril- 
ose. Always smaller than the other branch-leaves 
Chlor Oithoes cells Fs section triangular, with the base of the 
triangle free on the outer surface of the leaf; on the inner surface 
completely enclosed by the more concave h yaline cells, which are, 
aa et not united together for an epittetable distance 
Widely distributed in Europe and North America.
