these sulphates often occurring in a thin efflorescence' on their surface. During winter 
and spring, while the rainy weather lasts, the sulphate flats, owing to their level surface 
and imperfect drainage, are very wet, hut toy or before the first of July, when the dry 
summer has well begun, they have become the driest of all dry places, for the clay pre¬ 
vented the water from soaking in, and the soil is so thin that an adequate store of 
moisture could not toe laid up. Wliat, in early spring was the home of moisture-loving 
species, has in summer a coat of such species as Iva angustifolia, and Ambrosiw psitb- 
stadiya; but even these are matured earlier and are smaller on the sulphate flats than 
elsewhere, owing probably to their dryness. Even Opuntia Bafinesquii 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 home of Isoetes Butler i: It disap¬ 
pears between the middle of June and the first of July. It grows with Plantagopu 
silla, P. Patagouica , v.ar. aristdta , Polygala vertic/illata. Arena,ria Pitcheri, &c‘. There 
are occasional basins in the flats which contain more or less water, and here /. meldnd- 
poda 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.— (Steo. D. Butler, Almont , Iowa.
