\o6 BOTANICAL GAZETTE. 



This condition of things is seen especially along the east shore of 

 Lake Michigan. The mild climate ol this long strip of country 

 bordering -the lake renders profitable the growing of tender fruits, 

 and has caused this "'Fruit-belt" of Michigan to become widely 

 known. The Fruit-belt is not only peculiar in its great produc- 

 tion ol peaches and berries but also to a certain extent in its bo- 

 tanical characteristics. Many species of plants seem to find the 

 extreme limit of their range north or south in this belt. The fol- 

 lowing species are among those which appear to reach their limits 

 at South Haven, Mich., fifty miles from the head of the Lake. Of 

 course the limits as given here are only approximate, for north of 

 South Haven there has been no complete work done on the lake 

 shore. The interior ot the state has been well studied however by 

 C. F. Wheeler, E. F. Smith, and others, whose work is given in 

 Wheeler & Smith's admirable catalogue of Michigan plants. For 

 the south the Gazette's Indiana catalogue is often consulted. 



Lycopodimn complanatum,li., grows rarely at South Haven in 

 old choppings. It evidently reaches its southern limits about 

 the head of the Lake in Indiana. ( hid. Cat.) 



Botrychium ternatum, Swtz., var. dissectum, Eaton, seems to 

 reach its northern limits here, but var. obliquum, Eaton, extends 

 farther north into the center of the state. These are not reported 

 north of Southern Indiana in the Indiana catalogue, and do not 

 occur in Wisconsin, according to G. D. Swezey's list. 



Woodward ia angustifolia, Sm., occurs in very restricted 

 quantity in a dense hemlock wood, along with Goodyera repens R. 

 Br., Chimaphila maculata, Ph., Chrysosplenium Americanwn, 

 Schw., and the commoner Lyeopodiums. This beautiful fern will 

 soon disappear — as soon as the forests are removed. It is probably 

 a survivor of the extensive swamps which once covered the state. 



Phegopteris Dryopteris, Fee, occurs sparingly (Mrs. Milling- 

 ton). This is undoubtedly its southern limit in the West. 



Stipa avenacea, L., and Vilfa vaginaeflora, Torr., seem to reach 

 their northern limits here, although the latter occurs sparingly as 

 far north as Lansing. 



Juncus scirpoides, Lam., approaches its northern limit while 

 J. articulatiis, L., reaches its southern. J. nodosus, L., var. mega- 

 cephaluS) Torr., steiys north along the shore, and occurs in the 

 center of the state in Montcalm County (Wheeler & Smith's 

 Cat.) Clintonia borealis, Raf., reaches its southern range at South 

 Haven. The same is nearly true of Cypripedium acaule. Ait., which 

 is rare at this point. It is reported from one locality in Northern 

 Indiana. 



Goodyera repens, R. Br., reaches about its southern limit 

 here.
