MISSOURI BOTANICAL GARDEN. 



Mr. Lindheimer, it appears, began collecting and studying 

 the flora of Texas immediately upon his arrival there in 1836 

 but It was not till about 1842, after the political conditions 

 became more settled, that he collected in any quantity and 

 early m the following year Dr. George Engelmann su^^gested 

 to Gray that they cooperate with Lindheimer by namin- 

 and distributing his collections of Texas plants, so as to enable 

 him to devote his whole time to this work and thus advance 

 the cause of science in a land then almost wholly unknown 

 botanically. The outcome of this undertaking was the col- 

 lection of four fascicles of plants bearing the numbers 1 to 

 7^, and the publication of the first two parts of Plantae 

 Lindheimerianae describing a part of them. Fascicle I con- 

 tained 214 species collected in 1843; Fascicle II represented 

 the 1844 collection with nos. 215-318; Fascicle III consisted 

 of nos 319-574 of 1845-6; and Fascicle IV, comprising nos. 

 575-754, was collected in 1847-8. The specimens of the 

 collection of 1849-1851, here treated, were probably intended 

 to form Fascicle V. It appears that the first two fascicles 

 were issued in about 20 sets, only some 9 of which were at all 

 mil, while Fascicle IV contained about 40 sots* The col- 

 lection^of 1849-1851 contains about 650 numbers and there
