LETTER OF TRANSMITTAL. XV11 



and many of them described by himself. Dr. Carlos Spegazzini, of La 

 Plata, by far the most industrious and apt of living authorities on the Per- 

 austral Vegetation of Argentina, Eastern Patagonia and Fuegia, furnished 

 me with his valuable publications, and sometimes with his advice. Dr. 

 F. Kurtz, of the Museum of Cordoba, Argentina, sent me a set of the 

 botanical publications of that institution. And I have the honor to ac- 

 knowledge assistance, for identifications and otherwise, received from Sir 

 W. T. Thiselton Dyer, of the Royal Botanical Garden of Kew, and from 

 Dr. O. Hoffmann and Dr. E. Gilg, of the Koniglich Botanischer Garten 

 of Berlin. Dr. Hoffmann is entitled to thanks for Plate XXX, which 

 illustrates new species of Compositae, described by himself from specimens 

 collected by Dusen ; one of them by Hatcher. Dr. Gilg describes an inter- 

 esting new species of Draba which is in the Hatcher collection. 



Whilst some of the plates represent new species, others present long 

 known forms chosen as types of the very curious vegetation of the coun- 

 try. I am under obligations to the artist, Mr. J. Nugent Fitch, a 

 nephew and worthy successor of the artist of the Flora Antarctica. He 

 has shown marvellous skill in his work ; often having had very poor ma- 

 terial to work from. Mr. F. Van Iterson prepared the sketches, under 

 my supervision ; and Mr. R. C. DeMange prepared the text-figures, which 

 have been made strictly accessory to the text itself. This part has been 

 further helped by references to Britton and Brown's Illustrated Flora, and 

 to Engler and Prantl's Pflanzenfamilien, two great works which are well 

 illustrated and very accessible. 



Finally, I beg to thank you, Dear Sir, for the assiduity with which you 

 have endeavored to further the work, and also to thank the ever-patient 

 printers ; and most of all to recognize the Kind Providence who has kept 

 me in good health during these years which have been devoted in large 

 measure to a very enjoyable, though sometimes rather tedious task. 



Yours ever truly, 



GEORGE MACLOSKIE.
