﻿PLANTAE LINDHEIMERIANAE. 



PART III. 



BY J. W. BLANKINSHIP. 



On the death of Dr. George Engelmann his entire herbarium 

 was presented to the Missouri Botanical Garden by his son, 

 Dr. George J. Engelmann, and became the nucleus of the 

 herbarium of that institution. Among the duplicates that 

 came with the Engelmann herbarium was a considerable num- 

 ber of Lindheimer's Texas plants, which were at first supposed 

 to be the undistributed portion of the exsiccatae described 

 in "Plantae Lindhcimerianae," but later it was found that 

 they were an undistributed collection made subsequent to the 

 specimens described in that publication and represented the 

 work of Mr. Lindheimer during the years 1849, 1850 and 1851. 

 At the suggestion of the Director of the Garden, these collec- 

 tions have been carefully studied during the present year, 

 and this paper prepared to complete the work of the first two 

 parts of Plantae Lindheimerianae and render the data there 

 contained more accessible to those concerned with the flora 

 of Texas and regions adjacent, while the plants themselves 

 have been labeled and laid out into sets for distribution 

 to correspondents of the Botanical Garden. This final col- 

 lection of Mr. Lindheimer proves to be of considerable im- 

 portance, not only from its historical interest, but also from 

 the fact that it contains a large number of the type collections, 

 since described in various publications and many more from 

 the type locality, made by the original discoverer of the species, 

 while the great majority of the species are relatively rare in 

 many of our herbaria, the older distributions having gone 

 largely to Europe. The plants themselves are in a fairly 

 good state of preservation, considering the lapse of more than 

 half a century since their collection, the ravages of the usual 

 herbarium pests and the accidents of transportation and 

 storage during this time.
