Of these, the last of July, 1858, only the Aster acuminatus and great round-leaved orchis were conspicuously in bloom.
The most common flowers of the river and lake shores were: Thalictrum cornuti (meadow-rue); Hypericum ellipticum, mutilum, and Canadense (St. John’s-wort); horsemint; horehound, Lycopus Virginicus and Europæus, var. sinuatus (bugle-weed); Scutellaria galericulata (skullcap); Solidago lanceolata and squarrosa, East Branch, (goldenrod); Diplopappus umbellatus (double-bristled aster); Aster Radula; Cicuta maculata and bulbifera (water hemlock); meadow-sweet; Lysimachia stricta and ciliata (loosestrife); Galium trifidum (small bed-straw); Lilium Canadense (wild yellow lily); Platanthera peramœna and psycodes (great purple orchis and small purple fringed orchis); Mimulus ringens (monkey-flower); dock (water); blue flag; Hydrocotyle Americana (marsh pennywort); Sanicula Canadensis (?) (black snake-root); Clematis Virginiana (?) (common virgin’s-bower); Nasturtium palustre (marsh cress); Ranunculus recurvatus (hooked crow-foot); Asclepias incarnata (swamp milkweed); Aster Tradescanti (Tradescant’s aster); Aster miser, also longifolius; Eupatorium purpureum, apparently, lake shores, (Joe-Pye-weed); Apocynum Cannabinum, East Branch, (Indian hemp); Polygonum cilinode (bindweed); and others. Not to mention, among inferior orders, wool-grass and the sensitive fern.
In the water, Nuphar advena (yellow pond-lily), some potamogetons (pond-weed), Sagittaria variabilis (arrowhead), Sium lineare (?) (water-parsnip).
Of these, those conspicuously in flower the last of July, 1857, were: rue, Solidago lanceolata and squarrosa, Diplopappus umbellatus, Aster Radula, Lilium Canadense, great and small purple orchis, Mimulus ringens, blue flag, virgin’s-bower, etc.
The characteristic flowers in swamps were: Rubus triflorus (dwarf raspberry); Calla palustris (water-arum); and Sarracenia purpurea (pitcher-plant). On burnt grounds: Epilobium angustifolium, in full bloom, (great willow-herb); and Erechthites hieracifolia (fire-weed). On cliffs: Campanula rotundifolia (harebell); Cornus Canadensis (dwarf cornel); Arctostaphylos Uva-Ursi (bear-berry); Potentilla tridentata (mountain cinquefoil); Pteris aquilina (common brake). At old camps, carries, and logging-paths: Cirsium arvense (Canada thistle); Prunella vulgaris (common self-heal); clover; herd’s-grass; Achillea millefolium (common yarrow); Leucanthemum vulgare (whiteweed); Aster macrophyllus; Halenia deflexa, East Branch, (spurred gentian); Antennaria margaritacea (pearly everlasting); Actæa rubra and alba, wet carries, (red and white cohosh); Desmodium Canadense (tick-trefoil); sorrel.
The handsomest and most interesting flowers were the great purple orchises, rising ever and anon, with their great purple spikes perfectly erect, amid the shrubs and grasses of the shore. It seemed strange that they should be made to grow there in such profusion, seen of moose and moose-hunters only, while they are so rare in Concord. I have never seen this species flowering nearly so late with us, or with the small one.
The prevailing underwoods were: Dirca palustris (moose-wood), Acer spicatum (mountain maple), Virburnum lantanoides (hobble-bush), and frequently Taxus baccata, var. Canadensis (American yew).
The prevailing shrubs and small trees along the shore were: osier rouge and alders (before mentioned); sallows, or small willows, of two or three kinds, as Salis humilis, rostrata, and discolor (?); Sambucus Canadensis (black elder); rose; Viburnum Opulus and nudum (cranberry-tree and withe-rod); Pyrus Americana (American mountain-ash); Corylus rostrata (beaked hazelnut); Diervilla trifida (bush honeysuckle); Prunus Virginiana (choke-cherry); Myrica gale (sweet-gale); Nemopanthes Canadensis (mountain holly); Cephalanthus occidentalis (button-bush); Ribes prostratum, in some places, (fetid currant).
More particularly of shrubs and small trees in swamps: some willows, Kalmia glauca (pale laurel), Ledum latifolium and palustre (Labrador tea), Ribes lacustre (swamp gooseberry), and in one place Betula pumila (low birch). At camps and carries: raspberry, Vaccinium Canadense (Canada blueberry), Prunus Pennsylvanica (also alongshore) (wild red cherry), Amelanchier Canadensis (shad-bush), Sambucus pubens (red-berried elder). Among those peculiar to the mountains would be the Vaccinium Vitis-Idæa (cow-berry).
Of plants commonly regarded as introduced from Europe, I observed at Ansel Smith’s clearing, Chesuncook, abundant in 1857: Ranunculus acris (buttercups); Plantago major (common plantain); Chenopodium album (lamb’s-quarters); Capsella Bursa-pastoris, 1853, (shepherd’s-purse); Spergula arvensis, also north shore of Moosehead in 1853, and elsewhere, 1857, (corn-spurry); Taraxacum Dens-leonis—regarded as indigenous by Gray, but evidently introduced there—(common dandelion); Polygonum Persicaria and hydropiper, by a logging-path in woods at Smith’s, (lady’s-thumb and smart-weed); Rumex Acetosella, common at carries, (sheep sorrel); Trifolium pratense, 1853, on carries, frequent, (red clover); Leucanthemum vulgare, carries, (whiteweed); Phleum pratense, carries, 1853 and 1857, (herd’s-grass); Verbena hastata (blue vervain); Cirsium arvense, abundant at camps, 1857, (Canada thistle); Rumex crispus (?), West Branch, 1853 (?), (curled dock); Verbascum Thapsus, between Bangor and lake, 1853, (common mullein).
