ert of the spreading branches small, of medium size, to 
y large, ovate, ovate-lanceolate, Moet or almost linear ; 
ahoes generally narr ay more rarely broadly truncate and toothed 
or sometimes sharply acuminate. Border sometimes broader, some- 
rei narrower, at adea't baby broad. Margin generally toothed in 
the upper part, sometimes erg tt tae inrolled at the apex 
only or further down. Leaves when dry not rarely strongly undu- 
late or with weak or more seu metallic ee Chlorophyllose 
cells in section triangular, triangular-oval, trapezoid to rectangular, 
generally inserted between the hyaline cells on the outer surface 
and always free here; on Foe inner surface either completely 
enclosed by the more convex h e cells or free here also, at times 
median. Hyaline cells fibrillese or not. Pore-formation very 
various. Cortical cells of the stem generally with thick walls and 
rr umina, Me frequently not differentiated from the wood- 
cylinder ; non-porose and non-fibrillose. Stem-leaves varying much 
in form and sibehins: spatulate, lingulate to triangular-lingulate 
iangular to almost lanceolate, with or without pores and fibrils, 
generally with a wide border, much widened below. Colour of the 
ufts of various shades of green, yellow, brown, or brown-red, never
