THE AMERICAN BOTANIST. 115 



tell about animals and plants and they regard names merely 

 as a means of identification of the forms referred to. The 

 question once was, "who reads an American book?" If the 

 present tendency continues it will soon be "who can read an 

 American biological work?" 



Pennsylvania Wild Flowers. — About the middle of 

 May a party of five crossed the Susquehanna River at Millers- 

 burg, Penn., intent on finding as many specimens as possible 

 on which there were open flowers. Our territory covered that 

 part of Perry County between the landing and Mt. Patrick. 

 Directly after landing we discovered our old friend, common 

 blue violet, (V. cucitUata), and growing- near were the white 

 violet, {V. hlanda), and yellow violet, {V. piihcsccns). Scat- 

 tered among these was pale corydalis, (Corydalis glanca) and 

 not far away cinquefoil, (Potentilla Canadensis) celandine, 

 {Chelidoniuni ma jus) and wild cranesbill. (Geranium macu- 

 lahim). Soon one of our number spied what seemed at a 

 distance to be a white star-like flower but on coming nearer 

 we found it to be dog's tooth violet (Erythronium Dens-canis) 

 living within calling distance of its near relative yellow adder's 

 tongue (E. Aniericanuui) . As none of us had ever before 

 found the former, it was with difficulty that we left the patch 

 in which grew millions of a plant that we had considered quite 

 rare. Separated from this colony by a shallow stream, we 

 discovered smooth lungwort, {Mertensia Virginica) , wild 

 blue phlox, {Phlox divaricata) and Dutchman's breeches 

 (Dicenfra cueullaria) growing in such profusion tlint we 

 could but wish that the contributor to the American Botan- 

 ist, who lived where Dutchman's breeches would soon be a 

 rare flower, might have enjoyed with us the splendid flowers 

 and luxuriant foliage. Mingled with these we saw sweet 

 cicely, (Osiuorrhiza longislylis) , crow's-foot, {Dcntaria laci- 

 niafa) and bitter-cress, {Cardamine rhomhoidea). On the 

 margin of a near-by field, long-leaved stitch wort, {Stellaria
