THE FERN BULLETIN 



here is especially made to those which have gone un- 

 der the names of Botrychium obliquum and B. terna- 

 tum and their varieties, which are so variously treated 

 by different authors. It is sufficient for the present 

 purpose to state that ihe collections had without forc- 

 ing but rather naturally come into two groups, one of 

 which corresponds to the B. obliquum and the other to 

 B. ternatum var. intermedium as they are described in 

 the last edition of Gray's Manual, by whatsoever 

 name or names others may choose to call them. It 

 hardly needs mention that there are a good many var- 

 iations in the shape and size of the segments of the 

 barren fronds and for this reason, if for no other, ex- 

 amples from different localities are desirable. One of 

 these was obtained near Saegertown, Pa., and note 

 made at the time reads : U B. obliquum. Upland woods, 

 among beech trees, Aug. 31. Immature." The state- 

 ment, "immature" refers to a later maturation of the 

 spores of this group than of the other, to which my at- 

 tention had of late been more particularly called. The 

 two kinds had, however, been separated on other 

 grounds, the time of maturation came as an after- 

 thought, or induction from the facts observed. It had 

 been noticed that all called ternatum intermedium had 

 been obtained in August and had a more mature look, 

 while those that were labeled B. obliquum so far as 

 they were in fruit, were collected in September and 

 October, except this at Saegertown, but so backward 

 that it did not invalidate the observation that it was 

 a late-fruiting form. 



Taking the fruiting plants of B. ternatum inter- 

 medium in the order of their collection, and noting the 

 particular habitats as given in note-books or on the 

 herbarium sheets, the first is: (1) Pavilion, N. Y.,
