in the Isle of Wight in 1843, and to have since again dis- 

 appeared. (See Phytologist, iii. p. 745.) 



906. Littorella laciistris, vol. ii. p. 313. 



Perhaps ascends 200 yards higher in the East High- 

 lands, than was indicated for it in volume second. 



908. Chenopodium olidicm, vol. ii. p. 314. 



The south limit may be extended to Cornwall ; Mr. 

 Pascoe having seen a dried specimen of this species, 

 stated to have been picked in Cornwall. 



910. Chenopodiuvi urhicum, vol. ii. p. 315. 



The occurrence of tliis species in Scotland is unsatis- 

 factorily testified ; and perhaps it would be better to con- 

 sider Durham and Chester as the most northern counties 

 certainly known to produce C. urbicum. 



911. Chenopodium rubrimn, vol. ii. p. 316. 



The term ' Inundatal ' may be added to that of ' Via- 

 tical ', to express its places of growth. 



911*. Chenopodiuvi botryoides, vol. ii. p. 316. 



Of this species I have seen specimens from Norfolk 

 only. It occurs also in Suffolk, and possiblj'^ in Essex. 

 The other recorded counties are all erroneous, I fear; 

 that is, if the plant found about Yarmouth in Norfolk be 

 the true species, and which in general apj)earance resem- 

 bles C. urbicum rather than C, rubrum. But a small form 

 of the C. rubrum, that grows on the coast and on the sides 

 of muddy ponds, is occasionally mistaken for C. botryoides. 

 In restricting the known area of this latter to the counties 

 of Suffolk and Norfolk, with the possible addition of 

 Essex, considerable change would require to be made in 

 the formula of distribution. The provincial and comital 

 estimates will be taken at 2 and 3. The range of latitude 

 wiU be contracted to 53 (or 51) — 53 ; and that of tempera- 

 ture to 50—49.
