PTERYGOPHYLLACEA] 194 \_Pterygo P hyllum. 



Schwaegrichen published it in his Suppl. I, P. H, t. 100 (1816) and Bridel in 

 the Mantissa p. 103 (1819); Hooker afterwards named this moss Taylortaspach- 

 noides Muse. exot. t. 173 (1820). At p. 149 Bndel established Pterygophyllum, 

 citing Smith's H. lucens as a synonym, though he could hardly have then seen the 

 Trans. Linn. Soc., for in Bry. univ. ii, 341 (1827), he laments that it cannot be 

 maintained, as it was already occupied for the Tayloria.

Autoicous ; in depressed soft shining pale tufts, becoming whiter 

 when old ; stem and leaves complanate, with short and few branches. 

 Leaves narrow at base, rounded, upper larger, broadly ovate-oblong, 

 plane, lateral erecto-patent, broad ovate, all obtuse ; cells very lax 

 rhomboid-hexagonal, one or two rows at margin narrow rectangular. 

 Perich. bracts very small, oblong-lanceolate ; seta stout, smooth, reddish ; 

 calyptra conico-campanulate ; capsule elliptic, horizontal, small, castaneous, 

 becoming black by age ; lid convex-conic, rostrate ; teeth reddish-brown. 



HAB. Moist shady banks ; not rare. Fr. n 12. 



Paris records 289 species of this genus, and the type H. lucens is the only 

 species found in Europe. It is most frequent in the north of England, especially 

 in Yorkshire and the Lake District ; and damp hollows in clay banks are seldom 

 unoccupied by it.
