sedges. In contrast with this, the adjoining region, West Arctic 

 America, contains between 50 and 60 grasses and sedges. 



Out of 320 species belonging to the Greenland flora, all 

 except 29 are European ; of these 29 a few are endemic, the 

 rest Asiatic or American. Several species pi'esent in Greenland 

 are absent from East Arctic America. About 200 Scandinavian 

 forms are absent from Greenland which are present in America. 

 Several genera are absent from Greenland that are present in 

 all the other Arctic regions, e. g., Pari-ya, Astragalus, Valeriana, 

 Androsace, Aster, Myosotis, Caltha, Rosa, Ribes. 



The following are some of the genera that form the chief 

 part of the Arctic vegetation : — Ranuncidus, Saxifraga, Draba, 

 Potentilla, Hieracium, Arabis, Gentiana, Veronica, Primula, 

 Salix, Erif/eron, Androsace, Junciis, Luzula, Carex, Poa. No 

 genus is restricted to the Arctic Eegions proper, but several 

 genera are peculiar to the Arctic zone and mountain regions 

 taken together. 



That the Arctic flora, though the youngest of floras, existed 

 before the glacial period is proved by remains of plants 

 identical with existuig species found in strata near Cromer, 

 and near Zurich a stratum occurs containing remains of the 

 Arctic flora, where now the Vine and Chestnut grow. Fossil 

 remains of Tree-ferns and other southern plants have been 

 found in the far north. 



Mr. Brown exhibited an interesting series of Arctic plants. 



Evening Meeting. — November 15th, 1889. 



Mr. E. Noakes presented twenty volumes of ' Science Gossip.* 



Mr. A. J. Crosfield exhibited a living specimen of a Sala-

Mr. James B. Crosfield read the following note on a 'Lunar 

 Eainbow at Eeigate ' : — 



On the evening of October 9th a remarkably fine lunar 

 rainbow was seen at Eeigate. The moon was full at 1.26 on 

 the morning of the same day. At about 7.20 p.m. the eastern
