1857.] SPECIES DEPUNCT.E. 217 



learned correspondent Mr. Lees would send us some particulars 

 about this fine species. It has been hunted for about BlackwaU, 

 Greenwich^ and other places, where it was certainly found, and 

 there is reason to fear that it exists in these no longer. The fol- 

 lowing query is respectfully submitted to our correspondents : 

 Has Sonchus palustris been seen in or collected from a natural 

 station since 1830? j >..f4>... "^ ^^- -... ^mS''. 4.v ?.v. 



2. — Elymus geniculatus. 

 This fine Grass has for several years been a desideratum among 

 the collectors of British Grasses. Garden (cultivated) specimens 

 are now uncommon ; a genuine wild example has not been seen 

 in Britain during the last quarter of a century, since Dickson 

 first observed the plant growing on the bank of the river near 

 Gravesend. In the ' Sylloge Florae Em-opsese,^ p. 4.23, its range is 

 stated as follows: — Both, (south of Sweden), Angl. (England), 

 Batav. (Holland), Belg. (Belgium). Any information about the 

 occurrence of this species on the continent of Europe would 

 be very acceptable. English examples are scarcely expected. 

 N.B. — Curtis's account of Elymus geniculatus is the only one 

 which we have seen that is considered to be of any authority ; all 

 subsequent notices appear to be either copies of his or mistakes. 



3, 4. — Senecio paludosus and Senecio palustris 

 (Cineraria palustris). 



These appear to be a pair of our defunct plants. The Euro- 

 pean range of Senecio paludosus, as stated in the ' Sylloge ' above 

 referred to, is Austria (in part), Germany (North), HoUand, 

 Denmark, South of Sweden, England, Belgium, France (North), 

 Spain, Transylvania, Russia (South and Centre), Italy (North), 

 Hungary. 



The only British locality given for this plant is Streatham 

 Ferry, near Ely. Hudson quotes Ray as follows : — " Habitat in 

 fossis palustribus earumque aggeribus in insula Eliensi, near 

 Stretham Ferry." (Found both in the marsh ditches and on the 

 ditch banks near Stretham Ferry.) Relhan, in his ' Flora Canta- 

 bridgiensis,^ informs us that it was not to be found there in his 

 time, and he was contemporary v/ith Hudson. C. palustris {Ci- 

 neraria palustris) is another of the Stretham Ferry plants. This 

 is stated by Smith, E. Flor. vol. iii. 34, to be found in Norfolk. 

 Has this plant been seen in the latter-named county since the
