664 OLXxii. cyperacbjB. (C. B. Clarke.) [Eriophorum. 



Stamens 3-1, on the anterior side of nut. Style slender, glabrous, deci- 

 duous, long (in Sect. Lachnophorum short) ; branches 3 (accidentally 2 or 

 4) long. Nut sessile, trigonous, smooth, dusky black, apex narrowed. — 

 Species 10, Arctic or N. Temperate, except Sect. Lachnophorum. 



The genus was well-marked, until Bentham (Gen. PI. iii. 1052) removed the 

 comose species of Scirpus (the Sylvaticts Sect.) into it, on the ground that the 

 hypogynous bristles are similar. But in each flower of Eriophorumjihe bristles are 

 20-40 (or with 20-40 segments), while in Scirpus, Sect. Sylvaticie they are 6 j and in 

 their ligulate structure (see Fl. Dan. Suppl. t. 8) they differ greatly from Scirpus. 

 Also, in Scirpus Sect. Sylvaticte, the stems have leaf-bearing nodes in their upper 

 half. — E. filamentosum, Boeck. in JErigler Jahtb. v. is X.erotes leucooephala, Br.
