science. The following list shows that many genera are very 

 well represented here, and in some cases all the species of a 

 Linna?an genus are kept in this herbarium. In many cases 

 it is sufficient to quote the name of the species according to 

 Linna?us (and Linné fil.); but in some cases it is necessary as 

 far as possible to add a new classification according to our 

 present views of certain dubious species or series abound- 

 ing in forms. Part of this work has been done by post- 

 linnsean notes on the plant-sheets, mostly by J. E. Wikström 

 and S. N. Casström. Some few have besides been treated 

 by specialists in the middle of the 19th century along with 

 the other herbarium material of oldest date; thus e. g. 

 some Urticacece have been classified by Weddell, some Sper- 

 gularice by Kindberg, some Euphorbiacece by Müller Arg. 

 (1863). some few Pteridophyta by Baker etc. But it still 

 remains to subject these plants to comparative investiga- 

 tions, especially in the cases where distinct plants have re- 

 ceived the same name from Linnseus, although they may evi- 

 dently be reckoned as separate species. Sometimes the cipher 

 given by Linnseus is certainly without importance for the 

 knowledge of the species in its genus and accordingly quite 

 misleading. A circumstance which is of valuable aid in the 

 classification is that Linna?us's own often insignificant and 

 badly damaged specimen is completed by a large and very 

 well preserved specimen from Hortus Upsaliensis (through 

 Nietzel) in Montin's herbarium. As accordingly these Lin- 

 nsean plants deserve a critical investigation which might re- 

 quire a good deal of time in order to make out if the speci- 

 men really belongs to the said species, or any confusion 

 has been made by Linnseus, for the present only the begin- 

 ning of the list i. e. as far as Tetrandria is published here, 

 and the rest will be given in a future pamphlet. 



In the list now following, which in its order answers in 

 the main to Syst. Veg. ed. 13 (1774) and Suppl. plant. (1781), 

 will be found for every species firstly its name, and as far 

 as possible the name of the species in Linnaeus, next (in 

 italics) a citation of the words or signs which Linna?us and
