SPECIES OF MOSSES OF THE GENUS FISSTDENS. 559 



30. F. polyphylltts, Wils., Braithw. Brit. Moss-Fl. t.xii. A.— 

 S."W. England, Ireland, Portugal, and Spain. 



31. F. poltpodioides, Medio. Muse. Frond. Hi. p. 63, t. 27.— 

 Southern United States. Originally described from the "West 

 Indies. 



32. F. gkanbifrons, Brid. Fruit similar to that of F. adian- 

 toides. The Mexican F. strictus and F. insignis, Schimp., are by 

 Bescherelle referred here ; and F. sulgrandifrons, C. Midler, Bot. 

 Zeit. 1864, p. 339, cannot be distinguished. Fertile specimens 

 were gathered in N.W. India by Falconer. — Europe, North 

 America, N.W. India. 



33. F. majus. — F. adiantoides, Bry. Furop. and succeeding 

 authors, Braithio. Brit. Moss-Fl. t. xii. B. Areolation of cells 

 twice the size of those in F. adiantoides, and less obscure. — 

 Europe ; North America ; Tasmania. 



34. F. collinus. — Much smaller than F. majus, with its areo- 

 lation obscure as in F. adiantoides, yet with much larger cells. 

 Very variable in the height of its stems, from half to an inch and 

 a half. Fruit not different ; capsules in the short state nearly 

 erect, in the taller horizontal. — Chalk Downs, Sussex. Not iden- 

 tified off that formation, where it is common in the turf amongst 

 grass, and may be passed over as F. taxifolius. 



35. F. Langei, Be Not. Epilog, p. 479.— F. serrulatus, Schimp. 

 Syn. ed. 1, p. 107; Braithw. Brit. Moss-Fl. t. xi. C— Size, habit, 

 and appearance exactly that of F. serrulatus, Brid., found in the 

 Atlantic islands ; but with leaves everywhere having a distinct 

 coloured border, of which there is no vestige in the true F. serru- 

 latus. De Notaris says the pericha?tia are lateral. The areolation 

 of the leaves is also different.— S.W. England ; Portugal ; Italy. 



36. F. adiaxtoides, Medio. Muse. Frond, iii. t. xxvi.— F. crista- 

 tus, Wils., Mitt, in Journ. Linn. Soc.—Y. decipiens, Be Not. and 

 all recent authors ; Braithio. Brit. Moss-Fl. t. xi. D.— F. rupes- 

 tris, Wils. MS. Of this species Hedwig says, Muse. Frond, p. 61 :— 

 "Flos masculus alaris. Foemineus itidem alaris proprii individui ;" 

 and Bridel, Bry. F/niv. ii. p. 704, " Flos dioicus." In the ' Bryo- 

 logia Europea ' it was described and figured, without comment, as 

 monoicous. F. cristatus was a name given by Wilson before he 

 had distinguished his F. rupestris, which was a shorter state ;
