Excluded Species 1043 



in Europe and North America. Rhodora 29: 77-87. 1927.) In the absence 

 of a verifying specimen the typical form of this species is excluded. All 

 reports from Indiana are referred to Polygonum Hydropiper var. projec- 

 tum Stanford. 



Nat. of Eu. ; introduced in Newf., N. S., Mass. ; also in Oreg., Wash., and 

 Idaho. 



201. Polygonum hydropiperoides var. persicarioides (HBK.) Stan- 

 ford. (Persicaria persicarioides (HBK.) Small of Britton and Brown, Illus. 

 Flora, ed. 2.) (Rhodora 28: 27. 1926.) This plant has been reported from 

 Marshall and St. Joseph Counties. I have seen no specimen. Since the 

 range of the variety as now understood is far to the west of our area, I am 

 excluding it. 



Plains of Nebr. to Tex. and N. Mex. ; also in Mex. 



202. Polygonum ramosissimum Michx. This species has been reported 

 from Jefferson, Lake, Porter, and Vigo Counties. It is believed that these 

 reports were confused with P. exsertum, so, lacking a specimen, it is ex- 

 cluded. Rydberg, in his "Flora of the Prairies and Plains," gives the range 

 as Man. to B. C, southw. to 111., N. Mex., and Nev. It may be found 

 occasionally, however, as a waif eastward. 



203. Polygonum setaceum Baldwin. Reported from Jefferson County 

 by Young in 1871 before the present concept of the species. This report 

 should be referred, no doubt, to some other species. 



S. C. to Mo., southw. to Fla. and Tex. ; also in Asia. 



204. Polygonum tomentosum Schrank. This species was reported by 

 Nieuwland from St. Joseph County under the name of Persicaria tomentosa 

 (Schrank) Bicknell. A small, sterile specimen was found along the 1. 1. & I. 

 Railroad near South Bend, bearing the data 2733, June 1. I believe the 

 specimen is correctly identified but since it was found along the railroad 

 I am regarding it as a waif. 



Newf. to N. Y., Colo., and B. C. ; also in Eu. 



205. Chenopodium Bonus-Henricus L. Reported for Monroe County 

 by Andrews. Since there is no confirming specimen, it is excluded. 



Nat. of Europe. 



206. Amaranthus lIvidus L. Reported from Jefferson County by 

 Young. This is the only non-spiny amaranth he reported and John M. 

 Coulter in his catalogue of the plants of Jefferson County reports only 

 Amaranthus retroflexus. Since Coulter had access to Young's plants and 

 does not mention the species Young reported, I assume that Coulter dis- 

 covered the mistake and made the correction without comment. This is a 

 tropical species and has been found as an escape a few times about our 

 eastern seaports. 



Tropical S. A., e. Asia, and n. Africa. 



207. Froelichia floridana (Nutt.) Moq. A native of the southern 

 states. I reported this species before it was separated from Froelichia
