Aug. 16, 1875, Dry woods. The sporangia not yet 

 open, but full, globular, and turning yellow, or 

 about ripe. (2). Miller, Ind., Aug. 14, 1876. Dry 

 and warm, sandy woods, sporangia opening and freely 

 shedding spores. (3) Old Mission, Grand Traverse 

 Bay, Mich., Aug. 8, 1878. Dry, open woods, mostly 

 sandy. Sporangia beginning to open and shed the 

 spores. (4). Manistee, Mich., Aug. 10, 1880. Sandy, 

 pine woods. Sporangia opening freely. (5). 

 Mackinaw, Mich., Aug. 15, 1881. Rocky woods. 

 Sporangia opening. (6). Bagotville, Ha! ha! Bay. 

 Quebec, Canada, Aug. 20, 1888. Open clayey field. 

 Sporangia not yet opening. The specimen answers 

 quite well to the variety rutacfolium. The sterile 

 frond being rather small. (7). White Lake, Mich., 

 Aug. 23, 1899. Capsules open and the spores about 

 all fallen out. The plants were growing in a peaty 

 soil, with some admixture of sand, and were somewhat 

 crowded by low bushes. Hence they are taller and 

 more slender than those mentioned before them, ap- 

 parently because they stretched upward to meet the 

 light. They were also more abundant than T had 

 found them in other localities. 



I have not come across B. obliquum so often in 

 fruit. The time of visiting the localities mentioned 

 above being the summer season, there was no oppor- 

 tunity to examine the autumnal flora. Hence the ex- 

 amples of this are in the Chicago region, where all 

 Botrychiums, except B. Virginianum, are very rare. 

 The first on my list in fruit is from Porter, Md., Sept. 

 17, 1908. The sporangia are opening freely and the 

 spores falling out. It was growing at the edge of a 

 peaty swamp, timbered with gray-birch, tamarack and 

 white-pine. Being at the margin of the dune region,
