2 BOTANICAL GAZETTE, 



Flowers and Ferns of the Dells of the Wisconsin. — The collections of 

 Parry, who accompanied David Dale Owen in his geological recounoisance of the Up- 

 per Mississippi and its tributaries, indicated that there were in Central Wisconsin, be- 

 sides the local flora, plants of the Atlantic Coast — since extended botanically to the 

 beaches of the Great Lakes — of the Southern States and of the far Northwest. The in- 

 defatigable labors of the lamented T. J. Hale and Dr. I, A. Lapham have confirmed 

 the supposition in a general way, so far as it relates to the larger rivers ot Wisconsin 

 flowing westward. During the summer just passed we spent two weeks on and near the 

 Dells of the Wisconsin, and while the principal object of our visit was not botanical, we 

 believe our notes have sufficent interest to collectors elsewhere to repay the trouble of 

 editing them. We have aimed at completeness only with the ferns, attempting further 

 to give only a good idea of the characteristic vegetation. The time of our visit was 

 August. 



Flowers. — 1. Gorydalis glnucn, Pursh. Common enough on the more exposed 

 rock, but never found by us on the limestone in Southern Wisconsin, where we have 

 collected for several years, 



2. Arabis petrcea, Lam.. Very common, growing with SulUmntia on most shaded 

 rocks. 



3. Iludsonia tomeniosa, Nutt. Near the railroad bridge at Kilbourn City. Nearly 

 smooth and few-flowered stems. 



4. Mollugo vcrticillata, L. So thoroughly established everywhere that it is difficult 

 to believe it an immigrant. 



5. Talinum teretifoUum, Pursh. A large patch on the sand back of Allen's H(nise. 

 Our specimens nearly destroyed by growth in the portable press. With it, in abundance, 

 was the fungus Oenster hygrometricus, Pers. 



6. Potentillnfruticosa, L. Grows everywhere on the rock at the Dells, sometimes 

 fifty feet above the water. 



7. i?«6i/« species, ^/-{/icrws, Richardson ; sti'igosus, Michx. ; occidentalism L\'villosus, 

 Ait.; Canadensis, L. All common. Blackberries were worth only $1.25 per bushel. 



8. Sullivanlia Ohionis, Torr. and Gray. Quite common, especially in the side 

 glens. 



9. Heuchera hispida, Pursh., is also very common on the moist rocks, and was in 

 blossom, while the smoother plants of the prairies south had been in fruit ibr several 

 weeks. 



10. Hamamelis Virginica, L. Common. 



11. Aralia hispida, Michx. A large patch in fruit on the rock over the Cave of the 

 Dark Waters. 



12. Linncea horealis, Gronov. Only seen in the woods at Gates' Ravine. 



13. Campanula rotundifoUa, L. Common. 



14. Gaylmsacia resinosa^Toxv. anA Qv&y. Very common. Berries worth only $1.50 

 per bushel. 



15. Vaccinium Pennsylvanicum, Lam. Very common. Berries worth only $1.00 

 per bushel. 



16. Epigan repois, L. Very common. 



17. Gaullhen((procumbens,L. Very common. This and the three preceding are 

 also found in Southern Wisconsin wherever there is any considerable outcrop of sand- 

 stone, such places being known in all the regions around as Wintergreen Hills, etc. 



18. Chimaphiln umhellata, Nutt. Very common. Plants here indicate a very close 

 approximation of "cold, damp" and "dry" woods. 



19. Verbena strieta, Vent. Common on the sand plains near the river. T". brac- 

 teosa, Michx., grows everywhere with it. 



20. Motiardaptmciaia, L. Very common on the sand. 



21. FmlicMa Floridana, Moquin. Very abundant on the sand above Sugar 

 Bowl.
