[ganong] peat bogs of NEW BRUNSWICK 135- 



On the surface of the bogs another g-roup of cryptogamous phuits is 

 well represented — the Lichens. I made a careful collection of the species 

 on the Lepreau bog, and these have been studied and determined for me 

 by Miss Clara E. Cummings, of Wellesley College, one of our best author- 

 ities on American Lichens, and to whom I wish to express my best thank» 

 for this assistance, lu the list following, the notes in italics are by her ^ 

 the others are by myself, made at the time of collection. 



1. Clndoma rangi/erhia, (L.), Hoftni. 



c. alpesfris, L. Common in hollows on higher p:irts of tlie ho^. 



2. 1). sylvatica, L. Very well developed. Mixed with 1. 



3. form inajor, Floerk. Very large. From low places. 



4. Cladoniauncialis, (L.), Fv. In dense clumps. Not rare. 



3. Cladonia Boryi, Tuck. Above the average size. Not uncommon on high, 

 parts of the bog. 



6. Cetraria Islaadica, (L.), Ach. Not uncommon. 



7. form pldlyna, Fr. Very large. 



H. form between type and platyna, Ev. Very large. Not common. 



On the stunted trees on the bog grow : 



1. Alectoria jubata (L.). 



a. bicolor. Xot very distinct. Might almost as well be h. chalybei- 

 f or mis, Ach. 



2. Parmelia saxatilis (L.), Fr. Common. 



3. Parmelia jihysodes (L.), Ach. 



4. Usnea, barbata (L.), Fr. 



c. dasypoga, Fr. Young specimen ; may be form hirta. 



5. Cetraria lacunosa, Ach. 



Li re)K)vting upon these Lichens Miss Cummings remarks u|)on the 

 unusually luxuriant growth of some of them, a point of much interest in 

 comparison with the very stunted growth of other plants in the same 

 situations. In general, she says, those growing on the surface of the bog 

 are larger than usual, and those on the trees are smaller than usual. The 

 exact part taken by these Lichens in the bog formation will be discussed- 

 later. 



Of other cryptogamous vegetation there is little. Fungi occur on 

 the other plants, of course, but there is no trace of moulds, bacteria, etc. 

 On the walls of ditches at the Spruce Lake bog a toadstool, probably a 

 Hygrophorus sp., grows on the walls of ditches, and in a ditch at the 

 Lepreau bog, in cold, clear, running water, grows a bright green filamen- 

 tous Alga, probably a Ster/eoclinum. 



In enumerating the tlowering plant- they will be li.sted for biological 

 reasons as trees, shrubs and herbs. Two sets were collected, one from 

 Spruce Lake in 18."5, and the other from Lepreau in 1896. The deter- 

 minations of the species have been made for me by Mr. Walter Deane, of 

 Cambridge, which is sufficient guarantee of their correctness, and whom 

 1 wish here to thank for his kind assistance. The notes are mine, made 

 on the spot.
