234 Plante Lindheimeriane. 
The following brief account of the region in which the present collection of plants 
was made, drawn up by Dr. Engelmann as a preface to this article, having been 
received too late to take its proper place, is here subjoined. 
“In November, 1844, Mr. Lindheimer left the neighbor- 
hood of the Brazos River, where he had made his collections 
in 1843 and 1844, and reached in January, 1845, the shores 
of the Matagorda Bay. In this and the following month he 
collected on the lower Guadaloupe. From thence he went up 
this river about one hundred miles. Here, where the Comale 
Creek empties into the Guadaloupe, the Association of Ger- 
man emigrants, with whom he had for the present joined his 
fortunes, selected a place for settlement, and laid the founda- 
tion of New Braunfels, now a flourishing town, and the county 
seat of Comale county. 
“The year 1845 was spent in exploring the country and 
making excursions in the mountainous region to the west and 
northwest, at that time very insecure, being the haunts of 
wild Indian tribes. 
‘“‘In the following year, 1846, Mr. Lindheimer made large 
collections in the interesting country about New Braunfels, at 
the same time giving much of his time and attention to the 
affairs of the colony. 
‘The explorations of the year 1847 were extended north- 
west to the country watered by the Pierdenales River, where 
another German settlement, Friedrichsburg (or Frederiks- 
burg), had been founded. Collections were made partly here 
and partly near New Braunfels. Late in the fall an excursion 
in a northern direction into the granitic region of the Liano 
river furnished some interesting plants not observed before. 
«The year 1848 was spent principally on the Liano, where 
several new German settlements had been formed. But the 
country appeared to be less rich in botanical treasures than 
had been expected; the burning sun of the summer months 
had almost destroyed the vegetation on the granitic soil, not 
refreshed for months by any rains. The Comanches, Weckos,
