fusca, various species of Scirpus, and Eleocharis) and marsh-loving 
grasses predominating. The sandy ridges were covered with oaks, 
which with poplars and the species of plants which usually grow with 
them were to be expected from the character of the soil. 
My interest was chiefly centered in the plants of the sandy loam 
tracts on which there were found growing in greatest profusion the 
following species, which here are found much to the north and in most 
cases east of their recorded range in the state, which is quoted from 
Beal and Wheeler’s Michigan Flora (1892). 
Crategus Crus-galliL. Found on the border of a tract of sandy 
loam near the bay. Recorded from Lansing and southward. 
Lythrum alatum Pursh, reported from near Detroit and from Kalama- 
zoo, is here very abundant in damp places all over the district. 
Ludwigia polycarpa Short & Peter, from near Flint and in St. Clair 
county, is here common in marshy places. 
Silphium terebinthaceum Jacq. lonia, Macomb county and southward, 
this plant was exceedingly abundant in places covering large tracts of the 
poorer soil and grows as far north as Sebewaing, Huron county. 
Lacinaria spicata (L.) Kuntze grew with the Silphium and rightly 
earned its name of blazing star by making the country side brilliant in 
the middle of August. This plant has been found before as far north 
as Ionia county and from various other parts of the state to the south- 
ward and westward. 
Cacalia tuberosa Nutt., reported from the southwestern part of the 
state, Kalamazoo, etc., was also common here. 
Steironema quadriflorum (Sims) A. S. Hitch. was conspicuous and 
common. This plant has a southern range and seems not to be reported 
from so far north in the state. 
The Asclepiadaceze were generously represented by the following 
species : : 
Asclepias purpurascens L., reported from Ionia and Clinton counties 
and south. 
Asclepias Sullivantii Engim. Not reported in the “ Michigan Flora,” 
but found by C. K. Dodge on an island in the St. Clair river, and hav- 
ing a range from Ohio to Kansas and Minnesota. This plant was very 
abundant on the prairie soil in Akron township, Tuscola county, and 
probably extends northward into adjacent townships in Huron county. 
Acerates floridana (Lam.) A. S. Hitchc. Recorded from but one 
other station in Michigan, namely South Haven on the Lake Michigan
