wherever it appeared to him necessary or useful to add an explanatory 

 note. A few labels with MS. notes are pasted in, but I am not certain 

 of their author. The Equiseta are comprised in a fasciculus of nine 

 folios: the fasciculus is endorsed thus, — " 1169, Equisetum," in the 

 handwriting of Linneus. 



In the same apartment are preserved the author's own copies of the 

 first and second editions of the ' Species Plantarura.' In the first all 

 the species possessed by the author are distinguished by a particular 

 mark ; and the second is enriched with his own unpublished notes. I 

 will now endeavour to combine the information obtained from these 

 several sources, only quoting the published characters when requisite, 

 and adding remarks of ray own on every specimen. 



Folio 1. 

 Linneus. — 1. sylvaticum. 



E. N. — A single young specimen of Eq. sylvaticum of Smith, with 

 a very perfect catkin. 



Folio 2, pinned by Linneus to the preceding. 

 E. N. — Two mature specimens of Eq. sylvaticum of Smith, without 

 fructification. 



Folio 3. 



Linneus. — 2. arvense.

E. N.~Two specimens: right hand, a fertile specimen of Eq. ar- 

 vense of Smith, with perfect catkin ; left hand a mature specimen of 

 Eq. sylvaticum of Smith, without fructification. 



Folio 4, pinned by Linneus to the preceding. 



Linneus. — Hispania, 713. Loeft. 



E. N. — Three specimens without fructification, all of them appa- 

 rently starved or distorted : they probably belong to the Eq. arvense 

 of Smith. The Linnean MS. is on the back of the folio.
