Monoecious. 



[* A. Braun and others consider C. delicatula, Desv. as distinct from C. delicatula, 

 Ag., placing Desveaux's plant under C. aspera. They may be right, but there are no 

 authentic specimens at Kew of either ; yet from description they appear to be the same, 

 and Desveaux himself in bis Fl. de l'Anjou unites bis C. delicatula with C. frag His. 

 Tho oldest name for C. fragilis is C. globularis, Thuill. ; but as he also described it 

 under another name {C. capillacea) in the same book, it is perhaps better to retain the 

 name C. fragilis.]
