Botanical Intelligence. — The first part of A Flora of J\*orth 

 America., containing abridged descriptions of all the known indi- 

 genous and naturalized plants growing north of Mexico, arranged 

 according to the Natural System, by Dr. Torrey and Asa Gray, 

 has just been published. We have not yet had the pleasure of 

 seeing a specimen of this work, but when we have examined it 

 we shall notice it at length. 



We have received from Dr. Torrey the prospectus, stating 

 the plan and objects of this comprehensive work, which we give 

 below. When it is understood that Mr. Nuttall will contribute 

 the valuable information, which he acquired in his late visit to Co- 

 lumbia river, towards the completion of the work, and that both 

 Dr. Torrey and Dr. Gray have been three years in collecting 

 materials, in order to comprise every genus and species in its 

 pages, there can be no doubt but that it will form the most 

 valuable Flora yet published in this country: — 



" This work wiJl be published in three closely printed octavo 

 volumes, of about five hundred and fifty pages each. As con- 

 siderable time will necessarily be occupied in the publication of 

 the work, it is concluded, for the greater convenience of botan- 

 ists, to issue the volumes in separate parts, as soon as printed. 

 The first volume, therefore, which will comprise the Exogenous 

 Polypetalous plants, will appear in three parts, of one hundred 

 and eighty-four pages each; of whicii the first part is just publish- 

 ed. The second is now in press; and the third will follow as 

 soon as is consistent with its faithful execution. 



"The value of this Flora will be greatly enhanced by the exten- 

 sive contributions of Mr. Nuttall; who has communicated, for 

 publication in this work, his notes and descriptions of the plants 

 collected in his recent journey to Oregon and California, by way 

 of the southern ranges of the Rocky Mountains. Mr. Nuttall's 

 collections are very interesting, and comprise a large number of 

 new genera and species; a considerable portion of which were 

 obtained in a region never before visited by botanists.
