pond in a field near the north side of an east and west 
road, and about one mile east of Pilot Knob hill. The 
pond was dry on this date, but the species is submerged 
in this pond the greater part of the year. This species 
proved to be Isoetes Braunii Durieu. Both species of 
Isoetes were determined by Prof. L. 8. Hopkins. Spectr 
mens of the species of ferns and quillworts mentioned 
in this paper have been distributed among the larger 
herbaria of the United States.

In August, 1911, a magnificent specimen of the com- 
mon brake, four feet high, was brought home and planted 
in the yard along a wire-netting fence. On account of 
its weedlike propensities I did not trust it in the fem 
bed. In 1912 it sent up eight fronds, but none half se

inches wide, into the ground to confine the ferns withm 
a given space, but some rootstocks dived beneath the 
boards and sent up fronds six inches to four feet aways 
several coming up out of a bank eighteen inches abové 
the level of the area in which I had attempted to inclosé 
them. The bracken usually begins to grow during 7 
last week in April. Practically all the fronds are fertile 
and the brown sporangia ripen from the middle of Jun 
till into September. 
From a station thirty miles away I brought ine 
plants 
in my fern garden in August, 1911. I planted one . 
them in the open ordinary soil, another at the base ® 
of the purple-stemmed cliff brake and set the?
