664 CLXXII. CYPERACEJI. (C. B. Clarke.) {Eriophvrum* 



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

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

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

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



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

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

 hypogynous bristles are similar. But in each flower of Eriophorum^ihe bristles are 

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

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

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

 half. E. filamentosum, Boeck. in Engler Jafirb. v. is Xerotes leucocephala, Br. 



Sect. I. ERIOPHORTJM proper. Leaves moderately long. Style long.
