1862.] PLANTS CULTIVATED BY COLLINSON. 25 



humilis septenirionalium {R. arcticus), in Swedish^ 'Aker Bar/ 

 May, 1747. Dr. Beck, of Sweden, sent me the Rubus humilis, 

 or ChanKsmorus norvegicus. It makes a pretty show with its red 

 flower, and produces ripe fruit.^' 



Rubus Cham^.morus, Chamce Rubus, from Sweden, thrives 

 finely. "Mem. P^accinia nubls (Cloudberry), Chammnorus. 

 In August, in the highway from Settle to Appletreewick, a little 

 parish on the river Wharfe, as I went down a rugged rocky 

 hill, I observed this plant growing in the clefts of the rocks on 

 the right-hand side; it was then in berry. I took up some roots 

 and planted in my garden, where it grew ; but my gardener 

 pidled it up for a common briar," p. 47. 



Salix babylonica, Weeping Willow. — " Mem. Mr. Vernon, 

 Turkey merchant at Aleppo, transplanted the Weeping Willow 

 from the river Euphrates, and brought it to England, and 

 planted it at his seat in Twickenliara Park, where I saw it grow- 

 ing anno 1748. This is the original of all the Weeping Willows 

 in our gardens. 



"In July, 1765, I measured a Weeping Willow at Mr. Smcl- 

 ling's, at Godalmin, Surrey, of but fifteen years' standing. It 

 measured six feet in girth, or tAvo feet in diameter, and the 

 height in proportion." 



Loudon states in his ' Encyclopedia of Plants ' that this Wil- 

 low was introduced in 1692; but this early date is somewhat 

 discredited by Mr. Collinson's account. It is very improbable 

 that he should not have seen a tree so popular till more than 

 half a century after its introduction. Loudon also states that 

 the famous Weeping Willow in Pope's garden at Twickenham 

 was an accidental growth from some rods used ^ in a package 

 brought from Spain. The poet perceived some signs of vitality 

 in these twigs, and planted them, with the remark that the}/ 

 might possibly produce something which was not in England. 

 This is not impossible, but Mr. Peter Collinson's -^mera.," written 

 at the time, is higher authority than the poetical remark. 



Spirvea FiLiPENDULA. — ''Mem. Mr. Brewer, from Bradfield, 

 Yorkshire, sent me two roots of double FiUpendula, lately dis- 

 covered." And from another memorandum it appears to have 

 been found growing wild near Pontefract, and " considered to be 

 a great rarity."
