THE MOONWORT AND ITS ALLIES. 



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 lanceola- 

 tum in being stalked after the manner 

 of B. obliquum although the frond it- 

 self is more nearly like that of B. 

 Lunaria. 



In North America this species has 

 the same range as B. lanceolatum 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 Botrychi- 

 urns which have since been described 

 as a new species and named Botrychium 

 tenebrosum. Many botanists incline to 

 regard these specimens as forms of B.
