24 PATAGONIAN EXPEDITIONS: BOTANY. 



Hook., besides the epiphyllic Cololejeunea asperrima Steph. and Eule- 

 jeunea patagonica Steph. 



Among the epiphytic Musci some are conspicuous by their not uncom- 

 mon occurrence in large masses, such being Pilotrichella cuniingii and the 

 magnificent Cyathophorum splendidisshmtm (Mont.) Hpe. et Lor. These 

 and a few others of the mosses of the Aysen valley belong to genera 

 which have their proper home in the Tropics. Of some importance also 

 are Hookeria ancistroides Mont., Neckera chilensis Schpr., Ptychomnium 

 ptychocarpmn (Schwaegr.) Mitt., Cryphcea consimilis Mont., Rigodium 

 nano-fasciculatum C. Mull., Dicranum capillifolium Broth, sp. nov., Ec- 

 tropothecium spirifolmm sp. nov., Daltonia krauseana C. Miill. and D. 

 affinis sp. nov., Barbula crispatula C. Miill. and B. flagellaris Schpr., 

 Eriopus odontoloma sp. nov., Orthotrichwn nigritellum sp. nov., Cla- 

 domnium gracile (Hpe.) Mitt., Ulota fulvella Mitt, and U. niacro- 

 donta sp. nov., Amphidium cyathicarpum (Mont.) Jaeg., Pentastichella 

 pentasticha (Mont.) C. Miill. , Lepyrodon implexus (Kze.) Par. and L. 

 lagurus (Hook.) Mitt., Eriodon conostomus Mont, and Rhaphidostegimn 

 polytrichadelphus sp. nov., the last named living on Pogonatum den- 

 droides. 



On decaying trunks Musci are poorly represented, while Hepatica are 

 here comparatively rich in species. Of the former Rhaphidostegitini cal- 

 lidum (Mont.) Jaeg. and Acrocladium auriculatum Mitt, are the foremost, 

 being the only ones which occur en masse, at least within the forest 

 proper. On stones by the river and particularly on trunks fallen or 

 stranded on its banks, provided they are placed below high-water mark, 

 Dendrocryphcea gorveana (Mont.) Par. et Schpr. also occurs in very large 

 numbers. Scouleria patagonica (Mitt.) Jaeg., likewise abundant, lives in 

 the same way, although it prefers the stones ; this species, by the way, 

 being replaced on the stones higher up the river by large masses of Scia- 

 romium confluens (C. Miill.) Par. 



Of Hepaticce living on decaying logs I may name Anetira autoica 

 Steph. and A. pulvinata Steph., Lophozea ditsenii Steph., Lophocolea 

 attenuata Steph., L. lacerata Steph., L. leptantha Tayl., L. microstipula 

 Steph. and L. otiphylla, Cephalozia trisetosa Steph., Schistochila reicheana 

 and S. stratosa Mont., Lepidozia Iczvifolia Tayl. and L. chordulifera De 

 Not. and Jungermannia pigafettoana Mass., of which only the last occurs 

 in considerable masses.
