MACLOSKIE I REVISION OF FLORA PATAGONICA. 3 



to be in all probability 500 species, so soon as those collected by Darwin 

 during the voyage of he "Beagle" (in 1836) and more recently by 

 Hatcher, shall find men to examine and name them. Chardot also informs 

 us that 79 species of mosses are common to Magellan and New Zealand ; 

 60 common to Magellan and Tasmania; and Skottsberg finds 43 species 

 common to Magellan and the small island of Kerguelen. All these 

 figures become significant and interesting when regarded as evidence of 

 prehistoric connection of lands which are now widely separated. Our 

 knowledge of the Sedges, and also of the Hooked Sedges (Unciniae), of 

 the Southern lands, has been advanced by the valuable contribution of 

 Kiikenthal in Engler's Pflanzenreich ; and I have endeavored to utilize 

 this help.
