Lindheimer's Plants of Texas. 



In the third volume of the present Journal, p. 140, is 

 announced Mr. Lindheimer's intention of devoting some 

 time to the collecting of plants for sale, in Texas. The first 

 series has been distributed, and we can confidently say that 

 finer and better prepared, or better selected specimens, have 

 seldom come under the notice of Botanists, and Mr. Lind- 

 heimer has, as he pledged himself he would do, excluded 

 from them the common plants of the South-western States. 

 The species are all labelled and numbered, and a list of 

 names has been already published by Dr. Asa Gray, and 

 copies of this Catalogue have reached this country. 



One objeet of the present notice, is to give the oppor- 

 tunity for saying that, together with the sets ordered by 

 ourselves and friends, there have come two which are 

 undisposed of, and which can be had by applying to the 

 Editor of this Journal, at the price mentioned above, 

 (Vol. III. p. 140) with the addition of the share of freight. 

 One of the two contains 186 species, the other 181 species.
