Mniace^.j 231 [Orthopyxis. 



This plant is rarely found with fruit, and when this does occur as in 

 Norway and Lapland, it is only found in small quantity. It might be 

 confounded with the Var. imhricata of last species, but may be known by 

 the larger size, absence of tomentum, and broader very obtuse leaves. 



2. ORTHOPYXIS P. Beam. 



Prodr. p. 31 (1805). 



Growing on sandy banks or rotten trunks of trees. With or 

 without pseudopodia. Leaves entirely unistratose, with cells all of the 

 same form, round, incrassate with a large central papilla on each side. 

 Capsule regular, suberect. Male infl. gemmiform with filiform 

 paraphyses. — Der. opdoi straight ttv^is a capsule. 



Our species is the only one found in Europe, a second 0. heterostkha 

 (Hedw.) p. Beauv. occurs in N. America. The old authors mistook the 

 gemmae for male organs and this gave rise to the incorrect specific name.
