membranous when dry, margin ciliate, upper face sparsely hispidu- 
lous, and rough with numerous dot-like cystoliths, hairy on the 
nerves beneath and sometimes with a scanty whitish tomentum 
between the nerves; petiole shorter than and often about half the 
length of the blade, sometimes shorter. Stipules ovate, acuminate, 
scarious, hairy on the margin. Heads of flowers sessile, two or more 
at each node ; bracts 2-6, often 4; when 2, broadly ovate to elliptic, 
abruptly acute, 14 to ultimately 24 lin. long, enclosing a female
