470 Linnaan Society. 



The names on our Foreign list are those of ^fzelius, JussieUt Per- 

 sooriy and Schrader j men to whom I cannot affect to render even the 

 seml)lance of the respect due to them. 



Adam AfzeliuSj Professor of Botany at Upsal, — was, I believe, the 

 last of the pupils of Linnaeus, and distinguished like all the pupils of 

 that great man for his exact botanical knowledge. He contributed 

 two papers to our Transactions : " On the Botanical History of Tri~ 

 Jhlium alpestre, medium and pratense," in 1790^ and " Observations 

 on the Genus Pausus" in 1798. 



He resided in Sierra Leone for several years, and published his 

 principal work, *' Genera Plantariim Guineensium," in 1804; and 

 several Dissertations on the medicinal plants of that country, and 

 some other works. 



Antoine Laurent De Jussieu, Professor of Botany, Paris, — one of 

 the original Foreign Members of this Society, author of the " Genera 

 Plantarum secundum ordines naiurales disposita,'' and many papers in 

 the Annates and Mimoires du Museum d'riistoire Naturelle, in further 

 illustration of his views of the natural system. 



The date of the publication of the " Gewe-ra Plantarum'"in 1789,with 

 the fact that the life of this illustrious man terminated at a very ad- 

 vanced age without a second edition of that great work, are proofs of 

 the great acquisitions made in botany within the last forty-five years, 

 and of the hopelessness, save from one individual, of the labours of 

 Jussieu being equalled by any single botanist. 



I do not affect to speak of the merits or reputation of this eminent 

 man, but if there were any that can be claimed for him above even 

 the superiority of his intellect and learning, they were those of his 

 modesty and his entire freedom from undervaluing the labours of 

 others; and it is delightful to turn to a letter of his to Sir J. E. Smith 

 and to those of Bernard De Jussieu to Linnaeus, to observe hovir 

 purely these distinguished men regarded their mutual efforts to ad- 

 vance their favourite science. 



Christian Henry Persoon, A.M. — The name of Persoon will live 

 as one of the highest classical authorities on the Fungi, for his Synopsis 

 Plantarum, published at Paris in 1805, and well characterized by its 

 motto " In parvo copia," though highly useful in its day, was natu- 

 rally doomed to be superseded by later works of a similar kind. 



He contributed to our Transactions in 1799 a brief notice of a va- 

 riety of the Beech found near Gottingen, which he has termed Qwer- 

 coides, from the resemblance of its bark to that of the Oak. 



He published between 1796 and 1800 some of his earlier works on 

 Fungi at Leipsic.and his " Synopsis Met hodica Fungorum" appeared at 

 Gottingen in 1801. This was followed by his ^^ Icones pictcB rariorum 

 Fungor urn, "' atV Sinn, \n ISO?), [xn^l\\t* ' Novce Species LAchenum"\x\ 181 1. 

 His collections were purchased by the King of Holland, and the 

 annuity he received for them contributed essentially to the comfort 

 of the later years of his life, 



Henry Adolph Schrader, Professor of Botany, at Gottingen, — author 

 of the " Spicilegium Flora Germanic^'" in 1 794, and " Flora Germa- 

 nica,'' vol. ist, 1806, and various essays on Exotic Plants.
