turn and G. arvense), Burdock (Lappa major), Spiny Sow This- 

 tle fSouchus asper), Field Bindweed (Convolvulue arvensis), 

 Nighshade ( Solanum nigrum), Jamestown weed (Datura stra- 

 monium), Wild Tobacco (Nicoliana i^ustica), Lady's Thumb and 

 Black Bindweed (Polygonum Persicaria and P. convolvulus). 

 Hemp (Cannabis sativa), Brown Bent Grass (Agrostis canina), 

 Floating Foxtail (Alopecurus geniculatus) , Wire grass (Eleu- 

 sine Indica), Eragrostis (Eragrostis poceoides), Chess (Bromus 

 secalinus), and Barnyard grass (Panicum crusgalli) A few of 

 our naturalized plants seem to have escaped from a state of 

 cultivation, such as Red Clover (Trifolium pratense), Parsnep 

 (Pastinaca sativa), Hyssop (Hyssopus cfficinalis), Peppermint 

 (Mentha piperita), Horehound (Marrubium vulgare), Henbane 

 (Hyoscyamus niger), Buckwheat (Fagopyrum esculenlum) and 

 Timothy Grass (Phleum pratense). Several species seem to be 

 confined almost entirely to roadsides and waste places. Of 

 such we may name Hedge Mustard (Sisymbrium officinale), 

 Soap wort or Bouncing Bet (Saponaria officinalis), Cowherb 

 (Vaccaria vulgaris), which is not common, Indian Mallow (Abu- 

 tilow Avicennce), equally rare, Spotted Hemlock (Conium macu- 

 latum), Wild Teasel (Dipsacus sylvestris), Elecampane (Inula 

 helenium), Mayweed (Manila coiula), Tansy (Tanaceium vul- 

 gare), Great Mullein ( Verbascum Thapsus), an abundant pest in 

 old fields, Toad Flax or Butter and Eggs (Linaria vulgaris), 

 often a bold intruder into cultivated fields, Vervain ( Verbena 

 hastata and V. urlicifolia), Catnep (Nepeta Cataria), Hemp Net- 

 tle (Galeopsis tetrahit and G. Ladanum), Motherwort (Leonurus 

 cardiaca), Comfrey (Symphytum officinale), Groin well (Lithos- 

 permum arvense and L. officinale^), Stickseed (Echinospermum 

 Loppida), Hound Tongue (Cynoglossum officinale), Apple of 

 Peru (Nicandra physa/oides), Jerusaium Oak and Mexican Tea 

 (Ohenopodium bolrys and C. ambrosioidps), Smartweed (Polygo- 

 num hydrcpipev), Dock (Rumex crispus and B. obtusifolius) , 

 and Stinging Nettle ( Urtica dvnea). But few trees and shrubs 

 have been truly naturalized in the peninsula. Of such I have 

 recognized the Sweet Brier (Rosa rubiginosa), very common on.
