couples Rye and Winchelsea with Portsmouth as stations for his sea 

 mugwort, or Artemisia marina, as he calls it (at fig. 3), referred by 

 modern authors to A. caerulescens, and no doubt correctly; carefully 

 distinguishing our common A. maritima as white sea wormwood {Ab- 

 sinthium marinum album, p. 1099, fig. 1), thus showing that both 

 plants were familiar to him. Merrett (Pinax, p. 11) citing Gerarde's 

 figure of A. caerulescens, says it grows betwixt Deal and Dover, and 

 by the asterisk prefixed to the name implies that it was seen there by 

 himself; the authority of the Pinax is not, however, always the most 

 trustworthy, as Merrett appears to have been no greater botanist than 

 zoologist, and might easily have mistaken one species for another in 

 this instance, great as is the difference between them. How (Phyto- 

 graphia, p. ] 1) merely quotes Gerarde and Lobel, and probably takes 

 the former at his word without examination. Parkinson says nothing 

 of it as a native of Britain, nor does Morrison, both giving the coasts 

 of the Adriatic as its true region. The Lincolnshire station at Boston 

 rests solely on the testimony of Tofield as cited by Hudson ; Ray and 

 Petiver omit to mention or figure it, as both would certainly have 

 done had it been found in their time. In the Dillenian edition of the 

 Synopsis, indeed, we find reference made to a sea wormwood with a 

 broader leaf (Syn. p. 188-189, Nos. 3, 4), found by Plukenet and She- 

 rard, as well as of another observed by Dale near Colchester, which 

 Ray is inclined to think may be one and the same species or variety 

 with the former, but he is evidently ignorant of both. The very ob- 

 scure and short account of these two plants does not, however, favour 

 the idea that A. caerulescens was the species intended by Dale and 

 Plukenet; yet it is singular that Ray should not once allude, either in 

 the Synopsis or in his great work the 'HistoriaPlantarum,' to the alleged 

 occurrence, by Gerarde, of the lavender-leaved mugwort on the Sussex 

 and Hampshire coasts, even in the way of doubt or contradiction. As 

 Tofield is the only modern authority for A. caerulescens in England, 

 and even his testimony rests on the bare mention of his name by 

 Hudson, the inference may be fairly drawn, either that some variety 

 of A. maritima has been in every instance mistaken for the caerules- 

 cens, as we have seen to have been the case in this island, or that 

 like Echiuophora spinosa it may have occasionally appeared on our 

 shores for a limited time, but from climatic causes have been unable 

 to maintain a permanent footing. Both these plants inhabit the same 

 botanical region, much to the southward of our own country, and both 

 are recorded as having been found on the coasts of Brittany, but now
