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 Lindheimerianae,” 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.
