June. It is also a taller, fleshier plant 
and rather the more common of the 
two. 
The fronds are from four to twelve 
inches high and the blade, which is in- 
clined to be ovate in outline, is situated 
a short distance below the fruiting 
spike. In small plants it may be only 
pinnatifid but in the larger species it is 
usually twice pinnate. In all, the final 
divisions are rather blunt. The fertile 
portion is usually taller than the sterile 
and twice or thrice pinnate. The ster- 
ile division differs from that of danceola- 
tum in being stalked after the manner 
of B. oblequum although the frond it- 
self is more nearly like that of B. 
Lunarta. 
In North America this species has 
the same range as B. /anceolatum and 
in Europe both species are found to- 
gether. Recently botanists have ques- 
tioned the identity of our species with 
the European one. If they are not 
the same, our plant would be known 
as B. neglectum. 
In 1898 Mr. A. A. Eaton discovered 
in a New Hampshire sphagnum swamp 
a large number of peculiar Botrychz- 
ums which have since been described 
as anew speciesand named Botrychium 
tenebrosum. Many botanists incline to 
regard these specimens as forms of 2.
