Capsules 1-celled; some 2-valved, including a fine powdery 

 substance, others 3-valved, containing a few large grains or 

 seeds. Named from \VKOS, a wolf, and TTOVS, TTO^OS, a foot, 

 which the branches of some species are supposed to re- 

 semble.

Boggy places by the sides of mountains in various parts of the coun- 

 try, and sandy low grounds at Portmarnock. Two to three inches 

 high. Stems much branched, spreading, weak and slender below ; the 

 branches erect, leafy, cylindrical, obtuse ; those which bear the fructi- 

 fication longer and stouter than the others. The smallest of our 

 species.

 minal, solitary, sessile, short, cylindrical ; stem prostrate ; 

 branches dichotomous and fascicled ; leaves in four rows, 

 oblong, convex, acute, appressed. Br. FL ed. 3. p. 457. E.

 low colour." Hook. 



4. L. Selago, Linn. Fir Club-moss. Capsules in the axils 

 of the common leaves (not spiked) ; stem dichotomously 

 branched, erect, fastigiate ; leaves in about eight rows, linear-

Heathy and stony soils, most abundant all over the country. It is 

 known in Kerry as the (Virgin Mary's Furze.) " Used in the High- 

 lands, instead of alum, to fix colours in dyeing, and as an emetic and 

 cathartic, but it operates violently. The Swedes use it to destroy lice 

 on swine and other animals." Hook.
