[Translation.^ 



To the most distiuguishecl 

 Dr. Dayid van Eoyen, 



The distinguished Professor of Botany [Leyden], 

 Carl a'^on Linnio sends hearty greeting. 



I have to-day received the seeds most kindly forwarded by you, 

 among which are several which are uot in my garden. 



There was also sent, to my surprise, a leaf from Mexico, which 

 is, unless I am greatly mistaken, the nut-bearing tree with maiden- 

 hair-like leaves, Kaempf. amoen. p. 811 & 812, of a genus which 

 even now is wholly unknown ; I should be glad if you could give 

 to the Botanical world a full description of this plant. 



For both these gifts I send you my very best thanks. 



I have heard that the wife of the distinguished Professor Dr. 

 Adrian van Eoyen has recently died, which much distresses me ; 

 how does my kindest benefactor bear this sorrow ? I have also 

 heard that he himself is suffering from sickness, which has 

 alarmed me not a little. Do, if yoa are at any time writing, 

 send me news as to your uncle's condition : — I am in his debt, 

 and shall be so as long as I live. 



Have you ever seen Loasa, Jacq. obs. 3. f. 38, which as Ortiga 

 cJiilensis urens, Peuill. f. 43, two years ago was in the Botanic 

 Gardens at Vienna, Paris, etc., whence I quite recently obtained a 

 specimen. I have asked all Botanists for some of the seeds, but 

 there are no more specimens existing in any places known to me. 

 I should much regret it if Botanists should allow a plant so beauti- 

 ful and so rare in Europe to be lost, especially as it has never 

 befoi'e been seen in Europe. If you have any of the seeds, please 

 give some of them to me. 



Farewell — may you live happy in promoting the progress 

 and dignity of botany. 



Given at Upsala, IS April, 1769.
