Excluded Species 1087 



exterminate as ground-ivy. It is established in the grounds of the 

 University of Notre Dame, St. Joseph County. 



545. Lycopus asper Greene. This species was reported from St. Joseph 

 County by McDonald for Nieuwland. I have seen this specimen and it 

 should be referred to Lycopus americanus Muhl. 



Mich., Man., and B. C, southw. to Kans., Ariz., and Calif. 



546. Mentha aquatica L. There are two specimens of this European 

 species in the herbarium of Indiana University. They were collected by 

 A. H. Young in July, 1881, but they were never reported. Since these are 

 our only specimens and no data were given, it seems best to exclude 

 the species. 



Nat. of Eu. ; N. S. to Pa. and Ga. 



547. Mentha CardIaca Gerarde. I found this species in 1922 in a 

 pasture field in Spencer County. It was reported from Porter County by 

 Peattie on the authority of Churchill. Since there are no data concerning 

 the ability of this species to maintain itself it is best to regard it as a 

 migrant. 



Nat. of Eu. 



548. Mentha longifolia var. undulata (Willd.) Fiori & Paoletti. In 

 1923 I found this mint as a common plant in sandy soil along the roadside 

 on the site of a former habitation about 2 miles northwest of Monticello, 

 White County. A few years later I again noted it at the same place. Since 

 there are no other records, I regard this as only a chance introduction. 



Nat. of Eu. 



549. Hyptis radiata Willd. This species was reported from Jefferson 

 County by Young (Rept. Indiana Geol. Surv. 2: 273. 1871). If the identi- 

 fication was correct, no doubt it was a migrant. 



N. C. toward the coast to Tex. 



550. Hyoscyamus niger L. Black Henbane. This medicinal plant 

 was found by F. J. Hermann, June 20, 1935. It was an escape along the 

 road about 2 miles west of Angola, Steuben County. 



Nat. of Eu.; N. S. to Ont, southw to N. Y. and Mich. 



551. Physalis ANGULATA L. This species has been reported from the 

 dune area by Peattie and by Pepoon. Since it is a western species and it 

 was found in ballast, I regard these plants as migrants. 



Va. to Iowa, southw. to Fla. and Tex. 



552. Physalis ixocarpa Brotero. Tomatillo. E. D. Hull reported 

 this species in American Botanist 41 : 27. 1935. A few plants were adven- 

 tive in Gary, Lake County where they had escaped from cultivation. 



Introd. from the southwest. 



553. Physalis lanceolata Michx. There are several reports for this 

 species. The plant very much resembles Physalis virginiana and may have
