 given by Charles Martins. 



[The species marked with an asterisk (*) are found also in Lapland, those in italics 

 occur also ou the summit of the Faulhoru.] 



The Jardin is about 9,043 feet above tbe level of the sea ; its length, 

 is 2,625 feet ; its breadth about 985 feet ; its distance from the nearest 

 rocks on which some plants grow is at least 2,625 feet. The Jardin is

There are thus 87 flowering plants on the Jar-din. To these we 

 have to add 16 Mosses, 2 Hepaticas, and 23 Lichens, making a total of 

 128 plants which are found growing on this islet of vegetation sur- 

 rounded by perpetual snow. Of the 87 flowering plants 50 are marked 

 in italics, as beiug foimd also on the Fauihorn, an isolated Alpine 

 summit. These florulas may represent well Alpine vegetation at its 

 highest limit. Of the 87 species, 5 form a part of the Spitzbergen 

 Flora, viz. : — Ranunculus glacialis, Cardamine bellidifolia, Cerastium 

 alpinum, Arenaria biflorti and Erigeron uniflorus ; while 24 are found 

 in Lapland. The subnival flora of the Alps corresponds to that of
