84 EIGHTEENTH REPORT. 



frond near the middle of the stem, about equalling the fertile seg- 

 ment, or sometimes a little longer or a little shorter. No. 584^2^ 

 Sept. 5, 1S87, in moist, saud}^ places along the borders of shallow 

 streams. 



Ophioglossum vulgatum var. tseudopodum (Blake), N. Comb. 



Ophiof/lossiim ivihjatum forma Pseudopodiiui Blake, Bhodora, 15, 

 87, 1913. 



A larger plant than the species, the sterile frond more ovate, 

 y2 to 11/4 inches wide by 3 to 5 inches long, and tapering into a 

 petiole like base. No. 584, Sept. 5, 1887, in wet meadow lauds with 

 more or less sphagnum and other mosses. 



Ophioglossum vulgatum var. minus, Moore. 



This is the slenderest form of the species as found in Keweenaw 

 Co. The sterile blade is small (14 to % inch wide by % to 1% 

 inches long) ovate or elliptic, sessile near the base of the stalk 

 and far overtopped by the fertile segment, the whole jdant about 

 5 inches in height. No. 585, Sept. 5, 1887, on sterile hillsides 

 covered with a sparse growth of grasses and sedges. The whole 

 plant is yellowish while that of the other two varieties is green. 

 Undoubtedly this ])lant belongs here but it is the one that has been 

 reported in Beal's Flora of Michigan as O. Engelmanni. 



BoTRYCHiT'M LTjNARiA var. ONOXDAGENSE (Uuderwood), N. Comb. 



Botriich'mm Onondagense Underwood, Bui. Torr. Bot. CI., 30, 

 47, 1903. 



No. 1787, August, 1902, at Copper Harbor in oak and maple 

 woods. Bare. Forms are found which are intermediate between 

 B. Lunaria, and B. Onondagense indicating that the latter is only 

 an extreme form and therefore is better considered as a variety of 

 the former. 



Botrychium lanceolatum var. angustisegmentum, Pease and 

 Moore. 



The jdant listed in Beal's Flora of Michigan as Botrychium 

 lanceolatum is the one recently described as the variety angusti- 

 segmentum by Pease and Moore. It grows with B. Matricariae- 

 folium and other forms ap})ear to be intermediate and to intergrade 

 into either; further study may show that it is not specifically dis- 

 tinct from B. Matricariaefolium. No. 588, Sept. 5, 1887; usually 

 ill mould under hazel bushes, etc., but sometimes in grassy places 

 in the open. 



Botrychium Matricariaefolium, A. Br. 



It has been very conclusively shown that the Osmunda ramosa, 

 Roth, is not this species and that when Ascherson transferred Roth's
