514 GLEASON AND MCFARLAND: INTRODUCED VEGETATION 
THE INTRODUCED FLORA NEAR SUMMER RESORTS 
At Ingliside, at the northwest corner of the lake, are two. 
permanent residences and several summer cottages. A wagon 
road leads to Levering, about five miles away, and is well travelled. 
Very few farming operations are under way in the vicinity, and 
the introduced species are practically confined to dooryards and 
kitchen gardens. The whole settlement occupies not to exceed 
six acres, and the following introduced species occur: 
Poa compressa Brassica arvensis 
Poa pratensis Sedum acre 
Agrostis alba Trifolium repens 
Phleum pratense Trifolium pratense 
Setaria viridis Trifolium hybridum 
Agropyron repens . Euphorbia Cyparissias 
Bromus secalinus Malva rotundifolia 
Rumex elongatus Cynoglossum officinale 
Polygonum aviculare Lappula deflexa 
Polygonum Persicaria Solanum nigrum 
Polygonum Convolvulus Verbascum Thapsus 
Chenopodium album Nepeta Cataria 
Amaranthus retroflexus Plantago major 
Arenaria serpyllifolia Plantago lanceolata 
Cerastium vulgatum Ambrosia artemisiifolia 
Silene noctiflora Iva xanthifolia 
Lychnis alba Anthemis Cotula 
Lepidium virginicum Achillea Millefolium 
Capsella Bursa-pastoris Chrysanthemum Balsamitae 
Sisymbrium altissimum var. tanacetoides 
Sisymbrium officinale Arctium minus 
var. leiocarpum Taraxacum officinale 
Of these 42 species, three are obviously escaped from cultiva- 
tion, Euphorbia Cyparissias, Sedum acre, and Chrysanthemum 
Balsamitae var. tanacetoides. 
About half a mile east of Ingliside along the lake shore is 
another summer colony of four cottages, located in a gravelly 
pastured field. The occupants reach their cottages chiefly by 
boat from Ingliside, thus reducing the opportunity for the chance 
introduction of plants. Here the introduced flora is composed of 
the following 26 species:
