242 14. MALVACEAE. 



Agrarian region. Inferagrarian — Midagrarian zone. 



Descends to the coast level, in the Peninsula. 



Ascends, on the coast level, to West Lowlands. 



Range of mean annual temperature 52 — 48. 



Native. Littoral. Ou rocks of the coast, but very local. 

 Has been recorded from Essex and Norfolk ; but the Lava- 

 tera Olbia was the species mistaken for it in the former, 

 and in the latter it cannot be found. In the province of 

 Tyne, it has occurred only on ballast hills, and the ruins 

 of the Castle on the Bass rock, Haddingtonshire, are too 

 suspicious for the native locality of a plant otherwise con- 

 fined to the western coasts ; but it has long existed on the 

 Bass ; being recorded by Sibbald on that and other isles of 

 the Forth.

Alien or Incognit. " A few years since a new piece of 

 road was made through Epping Forest to Woodford. At 

 a spot called Fair-mead Bottom a large quantity of earth 

 was dug from the forest aud thrown up to raise the road, 

 for the distance of about half a mile. The following sum- 

 mer the sides of this piece of road were covered with various 

 plants, such as Senecio jacobaea, thistles, &c., and among 

 them a great number of plants of Lavatera Olbia, a species 

 not known, I believe, as a native of Britain. There is not 

 the slightest doubt that the seeds had been buried for a 

 vast number of years, and vegetated when brought to the 

 surface, as it seems impossible for the plants to have got 

 there in any other way. For three or four years they 

 seemed to flourish, aud flowered abundantly ; but now the 

 banks having become covered with grass &c., they seem to
