and the White Thorn ; a white-flowered Bramble (Uubus 

 odoratus] forms the underwood. The plants which are men- 

 tioned in company with the forest -trees, are, first, that 

 elegant little plant which was discovered by the daughter 

 of Linnseus, and is named after her, Linnaa borealis, with 

 pinkish-white blossoms ; it grows also in the Fir-woods of 

 Scotland. There is Chickweed Wintergreen too (Trientalis), 

 a kind of Currant, and a tall Azalea. 



In these forests we find, growing wild, a kind of Arum 

 (Catta), and a Latkma, which belongs to the Orobanche 

 family ; with dingy-looking blossoms growing all the way up 

 the stalk. It is a parasitical plant ; one species of it, L. squa- 

 maria, is often found in England growing upon the roots of 

 trees : there is likewise a kind of Willow. But the most 

 characteristic plant seems to be a very remarkable climber 

 called Panax horrida ; the epithet is well deserved, from the 

 spiteful-looking prickles scattered over the surface of the 

 very large leaves : " it renders the forest so dense that it is 

 difficult to penetrate it." This plant belongs to the Ivy 

 tribe (Araliacea) ; and the clusters of blossoms are very 

 similar in appearance to those of the Ivy. There is also a 

 species of an Orchidaceous plant called Cymbidiiim, a yellow 

 flower with dark brown spots.
