8 PATAGONIAN EXPEDITIONS I BOTANY. 



higher up the mountain slope. The Musci are comparatively numerous 

 and appear in masses here and there, particularly species of Dicramun, 

 such as D. imponens Hook. fil. et Wils., D. australe Besch., and D. 

 billardieri Schwaegr. The same applies to Campylopus flavo-nigritus sp. 

 nov., and Rhacomitrum lanugtnosum (Hedw.) Brid., to which should be 

 added, for the higher and treeless areas, Dicranum harioti Besch., Rhaco- 

 carpus humboldtii (Spreng.) Lindb. and R. patagonicus Broth, n. sp., be- 

 sides many species of the genus Andrecea. The Hepaticce, however, pre- 

 dominate here also, and the following should be singled out because of 

 their great abundance and because of their congregating into large mats : 

 Diplophyllum densifolium Hook., Lepicolea ochroleuca (Spreng.) Spruce, 

 Schisma chilensis De Not., Isotachis madida Tayl., and Adelanthns 

 uncifonnis (Hook, et Tayl.) Mitt, besides which I should not omit to 

 mention Lepidolczna magellanica Lam., Chiloscyphus horizontalis (Hook.) 

 Nees, Schistochila gay ana Gottsche and S. pachyla Tayl., each of these 

 now growing in distinct tufts, or again intermingled with other mosses 

 and conspicuous for their size or beauty, or for other reasons. 



As already mentioned, the shore-thickets are very dense, being made 

 up of some shrubs that thrive best here and scarcely occur outside of the 

 littoral proper. The following are found closely intermingled with one 

 another: Escallonia serrata Sm., Tepualia stipularis Gris., Veronica ellip- 

 tica Forst, Maytenus magellanica (Lam.) Hook, fil., Desfontainea spinosa 

 Ruiz et Pav., Fuchsia coccinea Ait., Pernettya mucronata (Linn, fil.) Gaud., 

 Pseudopanax l&tevirens Gay., and Philesia biixifolia Lam. These thick- 

 ets are also the chief resort of the lichens of this district, which here ap- 

 pear comparatively rich both in variety of species and profusion of indi- 

 viduals, not only on the twigs of the bushes, but also on the ground. 

 The following are the most important: Pseudocyphellaria hirsiita (Mant.) 

 Malme, P. fossulata (Duf.) Malme, P. orymcea (Ach.) Malme, P. orymcea, 

 subsp. flavicans (Hook, et Tayl.) Malme, P. freycinetii (Del.) Malme, 

 var. isidioloma (Nyl.) and Nephroma celhilosum Ach. Nearly always on 

 the outside of the thickets are found the phanerogamous Cotula scariosa 

 (Cass.) Franch., Apiiim graveolens L. and, sparingly, Gunnera magel- 

 lanica Lam. and G. lobata Hook. fil. Lastly, I may add that the twigs 

 of the bushes are also often taken possession of by mosses, particularly by 

 species of Ulota aud Macromitrium, such as Ulota fuhella Mitt, and 

 Macromitrium tenax C. Mull. The vegetation of the rocks by the shore
