oftim occurring in a thin efflorescence on their surface. During winter and spring, 

 while the rainy weather lasts, tlie sulphate flats, owing to their level surface and imper- 

 fect drainage, are very wet, but by or before the first of July, when the dry summer has 

 well begun, they have become the dryest of all dry places, for the clay prevented the 

 water from soaking in, and the soil is so thin that an adequate store of moisture could 

 not be laid up. What in early spring was the home of moisture-loving species, has in 

 summer a coat of such species as Iva angugtifoUa, and Ambrosia psilostachya ; but even 

 these are matured earlier and are smaller on the sulphate flats than elsewhere, owing 

 probably to their dryness. Even Opimtia Rdfinesquii grows on the flats, but it, too, has 

 an unhealthy dwarfish appearance, though for a different reason, as I take it ; it must 

 have been for it such a great effort to endure the protracted drenching in winter and 

 spring. These sulphate flats are the \\rime oi Isoetcs Butleri. It disappears between the 

 middle of June and the first of July. It grows with Plantago pusilla, P. Patagonicn, var. 

 aristata, Polygala verticillata, Arenaria Pitcheri, &c. There are occasional basins in the 

 flats which contain more or less water, and here /. melanopoda grows. It also occurs in 

 nearly all pools, ditches and wet weather streams. It is much more common than the 

 other, or at least appears so, as it is so much easier to find, owing to its greater size, 

 and paucity of companions. It disappears in August. Neither species will do well if 

 shaded. — Geo. D. Butler, Almont, Iowa.
