BOTANICAL APPENDIX, 



BY 



JOHN RICHARDSON. 



The following list of plants is not offered, as containing any thing like a full cata- 

 logue of the Flora of the country through which we travelled. During our summer 

 journeys, only a small portion of time could be allotted to Botanical researches, and 

 the constant and more important duties of the other officers prevented them from aid- 

 ing me in collecting objects of Natural History, which they were otherwise anxious 

 to do. Under such circumstances, a large proportion of plants must have escaped our 

 notice, and the disasters attending our return across the Barren Grounds from the 

 sea-coast, caused us to leave behind the whole collection made during the summer of 

 1821, with the exception of a few plants collected during the descent of the Copper- 

 Mine River, which were intrusted to Mr. Wentzel's care when he left us. The part 

 of the collection, which is lost, contained some plants, which I deemed to be new or 

 curious. 



In drawing up the list, imperfect as it is, I have received much assistance from able 

 botanists. To Mr. Brown, I am under the greatest obligations, not only for the libe- 

 ral use of the Herbarium and Library, which, so happily for science, have been placed 

 in his possession ; but, also for the friendly manner in which he aided my researches, 

 and condescended to solve the doubts so frequently presenting themselves to one little 

 versant in these pursuits. In addition to this general assistance, he kindly super- 

 intended the botanical drawings, and has enriched my catalogue with the lists of the 

 Cyperoideae (including the Carices) the Gramineae, Junci and Filices, and, with the 

 accounts of the genera Eutoca, Heuchera, and Cryptogramma. 



The collections of Pallas and Pursh, now belonging to Mr. Lambert, rendered the 

 power of referring to his valuable Herbarium an object of the utmost importance to 

 me ; and the desire of promoting the science, which so eminently distinguishes his 

 character, induced him cheerfully to accord it. 



Professor Schwaegrichen, when in London, named the Musci, which renders that 

 part of the list of high authority ; and Professor Hooker, by undertaking the examina- 

 tion of the Lichenes and Fungi, has stamped a value upon a portion of the catalogue, 

 upon which it was peculiarly desirable to have the opinion and authority of an emi- 

 nent cryptogamic botanist.
