240 Mr. Lhwyd to Mr. Ray, 



from the PiStra Imbofchata of Imperatus. Indeed I 

 have hitherto feen imperfeft Pieces of it > but! where- 

 as the Pittra Imbofchata (of which Kind of Figures 

 we have alfo fome Variety in England and Wales) re- 

 prefents only rude Branches imitating rather fome Co- 

 ralline or Sea-mofs than Trees ; the Gole-Jlat exhibits! 

 whole Branches with Leaves and Diftinftion of the 

 Veins and Texture of them. I have a fmall Piece^ 

 which feems to refemble a Branch of the Filix Teem. 

 very much > but the Specimen is very imperfect. * 



Mr. Bobari tells me the Gymnocrithon is the very, 

 fame with the London Tritictm Spica hordei. The 

 Alftne myof. Ian. Alpina grandiflora I do not queftion at 

 prefent to be a diftind: Plant from theAur. muris pul- 

 chro fl. albo, J. B. which is very common in thefe 

 Parts, but no where in North Wales (fuppofing this 

 no Miftake) that ever I could find. The Plant I 

 mean I never faw but at the higheft Part of all Snow- 

 ion : It's very woolly, but more efpecially before it 

 comes to flower, which is extraordinary membrana- 

 ceous, or thin > the Calix very long, crooked and 

 tranfparent, and divided at the Top with many 

 Notches $ the whole Plant every way bigger than 

 the Auricula muris. Since I fent you the Colledfcion 

 of Stones, I have difcovered feveral new ones, where- , 

 of you may hereafter expedt fome farther Account 

 from, &c.
