Of the species left aside for the present, Dicrmiella costata (many in S. Amer.), 

 PtvchomitriuDi fevnaudeziamini (other sp. in the Andes), Macroniityiiim saxaiile (many 

 in S. Amer.), Bartrauiia fernandcziima and Breutelia Masafuerae (many austral sp.) 

 may turn out to belong to an American element. The occurrence in Masatierra 

 of 8 endemic species of Thatiniium is astonishing, for not one is quoted for South 

 America, whereas related species are found in Australia-New Zealand, Oceania and 

 Malaysia; for this reason I have referred the species in Masatierra to the Pacific 

 element. 



IV. Hepaticae. 



Xo handbook equal to Brotherl's' comparatively modern account of the mos- 

 ses exists of the Hepaticae. ScillFKNERs treatment of this group in the 1st edition of 

 Xatiirl. Pflanzenfamilien is too antiquated to be of much use. Much important infor- 

 mation is, however, found in Hkrzog's work [i2g) as well as in Domin's paper (7^), 

 and also in this case Dr. Pkrsson kindly helped me, but to search the voluminous 

 s[)ecial literature of the last thirty years was not to be thought of. The number of 

 species given is, in many cases at least, too low, but I don't think this matters 

 very much. 



The following list is based on PlVAXs' and Herzog's papers (gj, ijo) with 

 a few alterations (/-?/). Several species credited to Juan Fernandez by Stephani 

 ( i^j-,^) but not mentioned by Herzog are included here; some of them are, perhaps^ 

 identical with other species.
