Cryptogramma Stelleri (Gmel.) Prantl 

 Slender Cliff-brake 



As far as known to the writer this beautiful little fern is seldom seen 

 in the state. The Michigan Flora reports it as found on Louse Isle and as 

 seen by the late G. H. Hicks at the Pictured Rocks on the south shore of 

 Lake Superior. In 1916 a visit was made to Grand Marais, Grand Island 

 and Munising, and an attempt was made to reach the Pictured Rocks which 

 lie between these two places. The old lumber roads and trails to the latter 

 locality were found to be impassable, but at Munising conditions were more 

 favorable and a search for the species was made at that place. The city is 

 situated in a depression or valley surrounded by high abrupt hills covered 

 with hardwoods. In the hills there are several small streams with over- 

 hanging rocky banks and precipitous falls. Under these overhanging rocks, 

 in crevices or on little benches or projections, the slender cliff-brake was 

 found in abundance, growing with Cystopteris fragilis, the brittle fern. 

 A further search in similar places, at least in the Northern Peninsula, will 

 undoubtedly bring to light other stations for this delicate species. 



Polystichum Braunii (Spenner) Fee 

 Braun's Holly-fern 



The Michigan Flora only mentions this fern as noted by O. A. Farwell 

 in Keweenaw County. This would seem to indicate that it is scarce and 

 has seldom been seen by our botanists, for, as compared with other ferns in 

 the state, it is certainly very distinct. The writer observed it first in 1916, 

 in the rich woods on Grand Island and near Peter White Camp in Alger 

 County. In June, 1917, it was found to be very plentiful on the alluvial 

 flood plain of the Salmon Trout River near the Huron Mountain Club on 

 the south shore of Lake Superior, northwest of Marquette, Marquette 

 County. 



Lycopodium tristachyum Pursh 

 Clustered Club Moss, Ground Pine 



The range of this club moss is given by Gray as "Dry sandy soil N. Me 

 to Del. and L. Superior," and by Britton and Brown as "Maine to Minne- 

 sota, etc." The Michigan Flora mentions it under the name of L. Chamaccy- 

 parissus A. Br. and says that it has been located in three places — Clare 

 County, Keweenaw County, and near Manistee. 



In 1908, while engaged in a botanical survey of the Saginaw Bay sand 

 dune district, the writer found it in abundance in Huron County but at 

 the time supposed it to be L. complanatum L. and so listed it. Since then 

 it has been noted as quite common from Mackinac to Houghton and Ke- 

 weenaw Counties inclusive.
