DUSEN: THE VEGETATION OF WESTERN PATAGONIA. 13 



lifera, Mastigobryum novce-zelandice Mitt., Lophocolea hmnilis and L. 

 trachyopa Tayl. Among the Musci the foremost place is occupied by 

 species of the genus Dicranum, of which D. billardieri, D. australe and, 

 generally, D. imponens, sometimes also D. nigricaule Aongstr. appear in 

 great numbers. Hypopterygium didictyon and H. thoninii, Htfpnodendron 

 krausei (C. Miill.) Jacq., Thamnium arbusculans C. Miill., Pterygophyllum 

 obscurum Mont., Ptychomnium cygnisetum, Rhizogonium mnioides, Bren- 

 telia dumosa Mitt., and Pogonatum dendroides Brid. are likewise worthy 

 of notice. 



On decaying trunks the Hepaticce are represented by Lophocolea, Lepi- 

 dozia, Jamesoniella, Aneitra, Schistochila, Isotachis, and other genera, 

 their commonest species being Lophocolea anomada (Mont), L. attenuata 

 Steph., L. trachyopa and L. textilis Tayl., Jamesoniella colorata, Aneura 

 conimitra Steph., Schistochila reicheana, Isotachis quadriloba Steph., 

 Lepidozia cucullifolia Steph. and L. phmitilosa. Among the Musci the 

 genus Dicramim again takes the leading place, with the same species as 

 are predominant on the ground. As they are quite common, Rhaphido- 

 stegium callidum (Mont.) and Stereodon lechleri Mitt., which grow in large 

 tufts, should not be omitted. 



The moss-flora of the standing trunks is quite rich, comprising, of the 

 Hepaticce, species of Lophocolea and Plagiochila, such as Lophocolea 

 Iinmilis, L. ftilvella (Tayl.), L. cucullistipula Steph., L. otiphylla and L. 

 homomalla Steph., Plagiochila bispinosa Ldbg., P. flexicatdis Mont., and P. 

 dura De Not.; further Madotheca subsquamosa N. et M., Radula intempes- 

 tiva Gottsche, Frullania stipatiloba Steph., and F. lobtdata Hook., Tricho- 

 colea verticillata Steph., and others. Worthy of mention among the Musci 

 are, Hypopterygiiun flexisetum Hampe, Pilotrichella krausei Lor. and P. 

 cumingii (C. Miill.) Lor. 



In lichens also these forests are poor. Strictly speaking, there are only 

 two species that one is sure to meet with, Sphcerophoron tener Laur., and 

 S. compressus Ach. One or two species of Sticta and Pseudocyphellaria 

 do occur, but they are rare. 



The thickets by the sea-shore are well developed and quite dense, which, 

 I think, may be set down to the favorable light, which prevails outside the 

 forest. They are chiefly made up of the following species : Tepualia 

 stipularis, Pseudopanax Icetevirens, Desfontainea spinosa, Pernettya mu- 

 cronata, Fuchsia magellanica Lam., Philesia buxifolia and Myrtus ugni
