518 GLEASON AND MCFARLAND: INTRODUCED VEGETATION 
during the logging operations. Each of these shelters from four 
to twelve introduced species, as follows: 
Poa pratensis Trifolium repens 
Phleum pratense Trifolium hybridum 
Agrostis alba Lappula deflexa 
Rumex Acetosella Cynoglossum officinale 
Polygonum Convolvulus Verbascum Thapsus 
Chenopodium album Cirsium lanceolatum 
Lepidium virginicum Cirsium arvense 
Capsella Bursa-pastoris Taraxacum officinale 
The chief logging road leading from this tract is nearly over- 
grown with thickets, but is still marked by numerous introduced 
species. These include every one of the preceding list and the 
following in addition: 
Poa compressa Wai rifolium pratense 
Rumex elongatus Chrysanthemum Leucanthemum 
Lychnis alba var. pinnatifidum 
Mention has already been made of the fact that nineteen 
introduced species occur along a road in another part of the 
hardwood region. Among these are four not mentioned above, 
Cerastium vulgatum, Silene noctiflora, Nepeta Cataria, and Plantago 
major. 
West of Bryant’s hotel there formerly stood a grove of hard- 
wood, lumbered in the winter of 1912-13. Observations of the 
flora made in 1911 showed one introduced species, Cirsium lanceo- 
latum, while in 1912 no introduced species was seen. At the 
present time 29 such species occur along the principal road through 
it, leading from Pellston to Bryant’s hotel. These are: 
Poa compressa Polygonum Convolvulus 
Poa pratensis Chenopodium album 
Phleum pratense Cerastium vulgatum 
Agropyron repens Silene noctiflora 
Secale cereale Lepidium virginicum 
Agrostis alba Sisymbrium altissimum 
Rumex elongatus Trifolium repens 
Rumex Acetosella Trifolium pratense 
Polygonum aviculare Trifolium hybridum 
Polygonum Persicaria Lappula deflexa
