On Fossil Vegetables from the Sandstone of Ayrshire. 283 



24. Jungermannia multifida, L. On moist rocks among mosses ; 

 fructifying in several places. 



25. — nemorosa, L. In a great variety of situations. 



Var. /3. pw'purascens, in Hell Cleft. 



Var. y. recurvifolia, on rocks near streams. 



26. — pinguis, L. In bogs and near streams. 

 27. — platyphylla,lj. Rocks. 



28. — polyanthos, L. On stones in the bed of the Balder. 



29. — puhescens, Schrank. Frequent on rocks (chiefly limestone) 

 near the Tees and its tributaries. I found perigonia in abundance, 

 but no calyces, though I searched most minutely. 



30. — reptans, L. Cronkley Scarr ; very sparingly. 



31. — riparia, Tayl. MSS. Sides of streams ; not common. 



32. — scalaris, Schrad. Frequent in moist situations. 



33. — serpyllifolia, Dicks. Near the High Force, Hell Cleft and 

 other places, yet nowhere abundant. 



34. — setacea, Web. Heathy situations near Maize beck and 

 Cronkley Scarr. 



35. — spinulosa, Dicks. Near the High Force and Caldron Snout, 

 but rather rare. 



36. — Tamarisci, L. On rocks and about the roots of trees. 



37. — Taylori, Hook. Cronkley Scarr and the vv^est side of Mickle 

 Fell. 



38. — Trichomanis, Dicks. Frequent. 



39. — trichophylla, L. Abundant in moist situations. 



40. — undulata, L. Maize beck. Dr. Taylor's opinion that this 

 is only a variety of /. nemorosa (* Flora Hibernica,' part ii. p. 61) is, 

 I fear, too w^ell founded. 



41. Marchantia androgyna, L. Exceedingly abundant on rocks by 

 the Tees, Ettersgill beck, and other streams.

XXXVI. — On the Fossil Vegetables of the Sandstone of Ayrshire.

[With a Plate.] 



Having observed, in visiting the Museum of the Royal Society, 

 that, although it contained many fossils of interest, especially a 

 very beautiful and complete series from England, presented by 

 the Earl of Cathcart, those of Ayrshire appeared to be altogether 

 wanting, I was induced to take advantage of a few months' re- 

 sidence in the district of Cuninghame in that county, during the 

 summer of 1843, to make a small collection of some of the prin- 

 cipal fossils of the locality for the purpose of presentation to the 

 Society's museum. 



The fossil vegetables which constitute the collection were ob- 

 * Read before the Royal Society of Edinburgh, Jan. 2nd, 1844.
