tions equally suggestive. It cannot be said that every plant at least 

 is known by the company it keeps. 



Another plant gathered by Spring Creek was Potentilla friiiicosa, 

 L., which is abundant in the swamps and wet sands by our lakes, and 

 throughout Michigan. In the dryer places of the swamp occurred 

 the pretty Linnaea borealis^ Gronov., which is common across the lake 

 in Michigan, and also to be found at Pine Station, Lake Co., Ind., 

 fifteen miles east of Chicago. This is the most southerly station of 

 which I am aware for this plant, away from mountains or hills. The 

 region at the head of Lake Michigan is a meeting-place for plants 

 from many directions; and, in consequence, furnishes a remarkably 

 varied and interesting flora. 



Two more of the plants of Mumford called to mind the Lake

brachycephaliis^ Engelm., quite often met with here. Nor should the 

 stations be omitted of two ferns, in localities not far away. One of 

 these, Camptosorus rhizophyllus^\AXik^ is common on ledges of lime- 

 stone in the eastern part of Le Roy, Genesee Co., in the deep ravines 

 of a forest locally known as the "' North Woods.** The other, Botryclu 

 turn lanceolaiuvi^ Angstroem, is sparsely found in woods in the south 

 part of Attica, Wyoming Co.

38. Note on the Round-leaved Violet.— Mr. Robinson s *'FIora 



of Essex County " is in error in stating that that county is the south- 

 ern limit, in Massachusetts, of Viola rotundifoUa. This plant occurs \ 

 in the vicinity of New Bedford, some sixty or seventy miles further 

 south, in a single locality, in which, within the past few years, it ap- 

 pears to have become more arbiindant.

39. Apparent Parasitism of List^ra australis.— I send a few 



green specimens of Listera australis ^ which has been blooming since 

 the middle of the present month (February). Last winter the plants 

 flowered in January, I think, (Chapman says July). This plant seems 

 almost semi-parasitic on Osfnmida cinna^nomeay from the roof -stocks of 

 which these specimens w^ere dug.

40. Woodwardia anc|ustifolia in Michigan. — Last September 



I was shown a^ sterile frond of a fern collected at South Haven, 

 Mich., by Mrs. L. A. Millington, which she supposed to be Wood- 

 wardia aiigustifolia^ Sm. A few days later I found a patch of the 

 same, containing well-developed fertile and sterile fronds, in a dark, 

 damp and forbidding hemlock forest, fourteen miles south of South 

 Haven. It \vas W. angustifolia, the rare fern of the Atlantic sea- 

 board. The localities where it was found were on the eastern shore 

 of Lake Michigan, in densely shaded lowlands. Only a single iso- 

 lated patch was discovered, about two feet wide by twenty long.
