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

 tie (Souchus asper), Field Bindweed (Gonvolvulue arvensis), 

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

 monium), Wild Tobacco (Nicoliana rustica), 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 (Bromia 

 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 officinalis), Peppermint 

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

 (Syoscyamus 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'), 

 Soapwort or Bouncing Bet (Saponaria officinalis), Cowherb 

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

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

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

 helenium), Mayweed (Maruta cotula), Taflsy (Tanacelum vul- 

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

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

 often a bold intruder into cultivated fields, Vervain ( Verbena 

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

 tle (Galeopsis tetrahit and O. Ladanum), Motherwort (Leonurua 

 cardiaca), Comfrey (Symphytum officinale), Gromwell (Lithos- 

 permum arvense and L. officinale), Stickseed (Echinospermum 

 Lappula), Hound Tongue (Cynoglossum officinale), Apple oX. 

 Peru (Nicandra physaloides), Jerusalum Oak and Mexican Tea 

 (Ghenopodium botrys and G. ambrosioides), Smartweed (Polygo- 

 num hydropiper), Dock (Rumex critpus and R. oblusifolius), 

 and Stinging Nettle ( Urtica dioica). But few trees and shruba 

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

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