.sea-green fesque grass ; carex arenaria, sea sedge, and occa- 

 sionally eryngium maritimum, sea eryngo, and j uncus maritimus, 

 sea-rush ; but to them may be added the following auxiliaries 

 which are by no means exclusively the productions of the sea- 

 shore : triticum repens, couch-grass ; galium verum, ladies' 

 bed-straw ■ ononis repens, rest harrow ; rosa spinosissima, 

 burnet leaved, or Scotch rose, with some composite, and a few 

 other plants. The sea buck-thorn, hippophae rhamnoides, is 

 unknown here; nor are dactylis stricta, upright cocks-foot grass, 

 panicum dactylon, creeping panic grass, orjuncus acutus, great 

 sharp sea-rush, all abounding on the shores of the mediterranean, 

 to be met with ; and the rare northern sedge, carex incurva, is 

 also a stranger. 



Though observations on organic remains may appear out of 

 place among minutes intended to illustrate the geography of 

 plants ; yet it may not be amiss to remark that not one of the 

 vegetables which have left impressions on our coal, &c. are 

 known to exist at the present day. The casts which frequently 

 occur in this coal field are those of the trunks of large trees 

 imbedded in sand-stone, and mineralized by silex ; but to what 

 species they belonged, it is impossible even to conjecture, as no 

 impressions of leaves remain : short thick stems resembling 

 those of the genus euphorbia, mineralized by sandstone with 

 iron pyrites, and coal-mtirks of ferns, like osmunda regalis, 

 filex mas, blechnum boreale, gigantic reeds, rushes, cones, and 

 a moss approaching to fontinalis antipyritica in shale ; fire- 

 clay, sandstone, and especially in ironstone nodules. When 

 erect, the euphorbias, reeds, &c. retain their proper shapes, but 

 are always compressed when found in a horizontal position.
