HAB. Hedges, fields, and moist banks. 



We have here been under the necessity of differing in opinion 

 from many esteemed authors, and uniting under one specific name 

 several plants which have been considered distinct by them. P. 

 curvisetum we conceive to be merely an accidental variety, hav- 

 ing frequently observed in the same patch of plants individuals 

 with curved and straight fruitstalks. P. Schreberianum, and P. 

 piliferum seem to us to owe their characters to the soil on which 

 they grow ; the former on a rich soil and in sheltered places ; 

 the latter in barren pastures and exposed situations, with us 

 generally near the sea, as about Yarmouth, where it is most 

 plentiful. The leaves have always a projecting hair-like point ; 

 but this is most remarkable in the var. piliferum, which has quite 

 a hoary appearance from their long white filiform extremities, 

 similar to what we see in Anictangium ciliatum, and the leaves 

 are generally short and obtuse. Mohr, whose authority is of 

 the highest importance, retains this state of P. cuspidatum as a 

 distinct species, (as do likewise Nees et Hornschuch), but
