at Kew. 6. The small but valuable collection of Edward Rud^e 

 (Hb. Kens.), at the Natural History Museum of the British 

 Museum, at South Kensington, London. 7. The northern 

 species described by Robert Brown (Hb. Kens.), at South Kensing- 

 ton. At South Kensington are also the herbaria of Thomas Wal- 

 ter, Ehrhart, Shuttleworth, and others. 8- The collection of 

 Scandinavian plants made by VVahlenberg, at Upsala (Hb. Wahl.). 

 At Upsala is also the herbarium of Thunberg. 9. A portion of 

 Wahlenberg's North American species, deposited in the Natur- 

 historiska Riksmuseum at Stockholm, (Hb. Holm.). Some of 

 Wahlenberg's types are not in existence, so far as known, but 

 they are such as are pretty clearly defined by collateral evidence. 

 The collection of Swartz, also at Stockholm, contains three of 

 Wahlenberg's types. ((7. polystachya, C. cladostachya and C. 

 scabrella.). 10. The very complete and invaluable collection of 

 arctic carices at Copenhagen (Hb. Havn.), comprising the types 

 of Drejer, Lange, and others. 11. The types of the Mexican 

 and Central American species founded by Liebmann, also at 

 Copenhagen, in the herbaria of Liebmann (Hb. Liebm.) and 

 CErsted (Hb. CErst). 12. Willdenow's collections (Hb. Willd.) 

 at Berlin. This herbarium contains most of the types of Muhlen- 

 berg and Schkuhn The specimens were probably furnished en- 

 tirely by Muhlenberg to Willdenow, and by Willdcnow lent to 

 Schkuhr. It appears .from comparisons of Willdenow's speci- 

 mens with Schkuhr's plates, that most if not all of the specimens 

 from which the drawings were made, were returned to Willdc- 

 now. Duplicates were retained by Schkuhr. 13. The large 

 general collections at the Imperial Botanic Museum at Berlin (Hb. 

 Berol.), containing the types of Bceckeler, and some of those of 

 Kunth, and other authors. 14. The collection of Schkuhr (Hb. 

 Schk.) at Halle. 15. The specimens representing Presl's types 

 of Reliquiae Haenkeanae, at Prague (Fib. Presl). 16. The old her- 

 barium of AlHoni (Hb. All.) at Turin, Italy. Some of Allioni's 

 types are not in existence, so far as known, and it appears that 

 some of his species are founded solely upon Haller's descriptions. 

 17. The plants of Lamarck (Hb. Lam.) at the Jardin des Plantes, 

 Paris. This invaluable collection has but recently been added to 

 the large collections at Paris, by purchase from the estate of the
