DANIELS ON FLORA OF STURGIS, MICHIGAN. 147 



northern and northwestern sandy and wooded, its western and southwestern low 

 and filled with rushes, flags, and other amphibious plants. It is a paradise of wil- 

 lows with hybrids enough to perplex a botanist for a lifetime. Some rare plants 

 inhabit its shores. Cassia nictitans, L. (found so far as known only here in the 

 state). Phlox subulata, L., Synthyris Houghtoniana, Benth., Stachys hyssopifolla, 

 Michx., and Bouteloua racemosa, Lag. 



Of xerophytic formations there are but few traces. The dry sandy .shores of 

 Lake Minnewaukon and other lakes furnish a few characteristic species. Dry 

 knolls in oak woods, light sandy tracts, etc., have a few xerophytic plants; also 

 barren places along railroads, where the best soil has been taken off, yield a small 

 number. But any distinct flora, such as that of the dunes of the great lakes or the 

 pine barrens of northern Michigan, is totally absent. 



The following arrangement of plants conforms sufficiently close, perhaps, to the 

 character of the region: 



I. — Xerophytes. 



A. Sterile banks and lake borders. 



B. Barrens and light sand. 



II. — Mesophytes. 



A. Remnants of prairie vegetation. 



B. Oak openings. 



C. Alluvial bottoms. 



III. — Hydrophytes. 



A. Swales in woods, and swamps. 



B. Prairie bogs. 



C. Borders of streams, ponds, and lakes. 



D. Aquatics. 



* 

 IV. — Parasites and saprophytes. 



(Excluding those with green foliage.) 



V. — Anthropophytes. 



A. Weeds. 



B. Forage plants. 



C. Escapes.

 Catalpa speciosa. Warder. 



The following species, reported previously only from the Upper Peninsula, is 

 found at Sturgis: 



Potamogeton Hillii, Morong. 



The known range of the species named below is perhaps extended somewhat: 



Brasenia peltata, Pursh.
