470 Mr Philip Sewell on the Flora of [sess. liii. 



In Vclxtligheten pa Sibiriens Nordkust will be found full 

 references to the literature of previous expeditions. 



None of our countrymen except Wiggins (who, however, 

 engaged in no scientific work) have, since the time of the 

 early Merchant Adventurers, explored these Arctic regions 

 Ipng to the south and east of Novaya Zemlya. It has been 

 left to the enterprise of the Swedes, and especially are we 

 indebted to the voyages of the " Vega " and of the 

 " Dijmphna " for information as to the botany of these 

 regions. 



There had, however, been overland journeys to the 

 northern shores of Asia, and thence to Novaya Zemlya, 

 the results of which have been incorporated in Sir Joseph 

 Hooker's Outlines of the Distribution of Arctic Plants (see 

 Trans. Linn. Soc, vol. xxiii.), and in the works above cited. 



The following abbreviations have been made use of : — 



X — observed during the voyage of the "Labrador." 

 D =: obsei-\' ed during the voyage of the " Dijmphna " 



from shores of the Yugor Straits. 

 V = observed during the voyage of the " Vfega," or 



recorded in Dr Kjelhnan's summary of 



plants known from the northern coast of 



Asia as far as to Cape Tcheluschin. 

 T = other records from the Taimyr peninsula given 



in Dr Warming's Summary. 

 Z = recorded from Novaya Zemlya. 

 L = observed on the Island of Vardo by Pastor 



Landmark. 

 — = known from West Siberia, but more to the 



south. 



Plants marked with tlie asterisk (*) are British species; 

 those in brackets were not oljscrved Ijy me. Those marked 

 as " indigenous " were collected at the Yugor Straits, and are 

 also native to Lapland, though not observed there by me.
