420 CLVI. CYPERACEH (CLARKE). | Fimbristylis. 
As throughout the Order Cyperaceae, the apparently transverse wrinkles or 
wavy lines on the nut of F. evilis, ure due to the longitudinally oblong superficial 
cells, the ends of which (by a thickening at their junction) give the appearance of 
transverse wrinkles. #, Hensii shows none such ; because the superficial cells are 
nearly quadrate.
