ART. XV. — PLANTS LINDHEIMERIANTE ; AN ENUMERATION OP 

 THE PLANTS COLLECTED IN TEXAS, AND DISTRIBUTED TO 

 SUBSCRIBERS, BY F. LINDHEIMER, WITH REMARKS, AND DE- 

 SCRIPTIONS OP NEW SPECIES, &c. By Geohce Engelmann and 

 Asa Gray. 



Mr. Lindheimer's plan for exploring the botany of Texas, 

 and preparing specimens of dried plants for distribution, was 

 announced in Silliman's Journal for July, 1843. The collec- 

 tion of that season, owing to various misfortunes, having been 

 much smaller than was anticipated, it was thought best to 

 defer its distribution until that for the year 1844 should 

 come to hand. A part of the second collection was lost in 

 the course of transmission to St. Louis ; those which were 

 received in sufficient quantity for distribution extend the 

 number to 318. Mr. Lindheimer is now entering upon an 

 unexplored field west of the Colorado River, and we may 

 confidently expect that a rich harvest of peculiar plants will 

 reward his efforts during the present season. This collection 

 will be assorted and distributed without delay, and our ac- 

 count of them duly published in the pages of this journal. 



The collection of 1843 was made on Galveston Island, 

 around Houston, on the Brazos, &c. The series commences 

 with some species of Ranunculus^ allied to R. pim/Zws, 

 which, having been long since distinguished by Dr. Engel- 

 mann, and communicated to various botjmsts under the 

 following names, the characters as assignedf.&y him are here 

 given. ' j
