Plants of Boone County, Kentucky. 129 
ARISTOLOCHIACEAE: 
Asarum canadense L. Common in rich woods. 
Aristolochia Serpentaria L. In wooded districts, rare. 
POLYGONACEAE: 
Rumex Britannica L. In wet places, rather scarce. 
(This probably should be R. altissimus Wood. Mr. Deam tells 
me that Britannica occurs in Ind. only in the northern counties, 
while altissimus is common along: the Ohio R.) 
Rumex crispus L. Abundant in fields and meadows. 
Rumex obtusifolius L. Very common about dwellings. 
Rumex Acetosella L. Common in poor soil. 
Polygonum aviculare L. Abundant in door-yards, ete. 
Polygonum erectum lL. With the last. 
Polygonum amphibium L. Occasional in wet places. 
(This species has been found in Ind. by Mr. Deam but twice, 
while P. Muhlenbergii (Meisn.) Wats., which in Gray’s 5th Ed. 
was not separated from amphibium, is abundant in the counties 
along the Ohio, so my report is doubtless an error, and should be 
changed to Muhlenbergii.) 
Polygonum Hydropiper L. Wet ground, common. 
Polygonum acre HBK. Abundant in waste places. 
Polygonum orientale L. An occasional escape about dwellings. 
Polygonum virginianum L. Rich thickets, common.
