COLLECTION SECOND, 1844. 



Mr. Lindheimer's Collection of 1844, was made between 

 the Brazos near San Felipe, and the Colorado River, in the 

 neighborhood of Cat Spring of Mill Creek, the settlement of 

 Industry, and thence westward towards the Colorado, and 

 along its bottom lands. The prairies are partly of a light and 

 even sterile sandy soil, and partly of a stiff' clayey soil. The 

 bottom lands consist of a stiff black soil. Near Industry, and 

 on the Colorado, rocks of a secondary sandstone (probably a 

 subcretaceous formation) appear, on which several species of 

 Cactus are found. In the prairies ant-hills are not uncom- 

 mon, and on old and deserted ones a rich harvest of peculiar 

 plants may be made. The numbers run on consecutively 

 from the end of the former year's collection. Additional 

 specimens of the following plants of that collection, gathered 

 again in 1844, are distributed to subscribers (without being 

 reckoned) under their former numbers, namely: No. 7. 

 Cocculus Carolinus, DC, in fruit. — 8. Strepianthus hya- 

 cinthoides, Hook., with linear leaves ; the flowers nodding, 

 the long siliques erect. — 18. Paronychia Drummondii ; hand- 

 some specimens, gathered in May, just coming into flower. — 

 24. Sida Lindheimeri, nob. ; specimens in finer state than 

 before. — 29. Rhynchosia minima. — 39. Dalea aurea. — 40.

 Undoubtedly indigenous, flowering in March. — 55. (Enothera
