Excluded Species 1081 



497. Bartonia iodandra Rob. This species is endemic in Newfound- 

 land. I reported it from Steuben County but 1 am now referring the 

 specimen to Bartonia virginica. 



498. Gentiana linearis Froel. (D '« sy Stephana linearis (Froel.) Britt. 

 of Britton and Brown, Illus. Flora, ed. 2.) This species was reported by 

 Clapp in his Catalogue of Medicinal Plants of the United States, p. 160. 

 1852. He refers to finding his specimen on the barrens. At that time the 

 distinction between this species and Gentiana pubervla was not clear, and I 

 believe he had the latter because I collected it there and because Clapp 

 did not report Gentiana puberula. It was also reported by Ball for Lake 

 County in 1884. Since Ball did not report Gentiana puberula, which occurs 

 there, I refer this report also to that species. 



499. Gentiana quinquefolia L. I am referring all reports of this 

 species to its variety occidentalis (Gray.) Hitchc. I have not seen the 

 typical form in the state. 



S. Maine to Ont. ; southw. to Fla. 



500. Apocynum androsaemifolium var. incanum A. DC. All reports 

 of this variety should be referred to the species. 



501. Apocynum cinereum Nieuwland. (Amer. Midland Nat. 3: 56-57. 

 1913.) This species was reported for Lake County. Woodson (North 

 Amer. Flora 29 : 191. 1938) refers this species to Apocynum cannabinum 

 var. pubescens (R. Br. )A. DC. 



502. Apocynum isophyllum Greene. (Greene. Leaflets of Bot. 2: 166. 

 1912.) Reported for St. Joseph County. Woodson (North Amer. Flora 29: 

 192. 1938) refers it to Apocynum cannabinum var. glaberrimum A. DC. 



503. Apocynum platyphyllum Greene. (Greene. Leaflets of Bot. 2: 167. 

 1912.) Reported for Wells County. Woodson now refers this to Apocynum 

 cannabinum L. (North Amer. Flora 29: 191. 1938.) 



504. Apocynum tomentellum Nieuwl. (Amer. Midland Nat. 3: 55-56. 

 1913. On page 166 of same publication he changes name to Apocynum 

 tomentulosum.) Woodson (North Amer. Flora 29: 191. 1938) refers this 

 species to Apocynum cannabinum var. pubescens (R. Br.) A. DC. 



505. Asclepias decumbens L. This species was reported from Knox 

 County by Thomas and from Marshall County by Clark. It is doubtfully 

 distinct from Asclepias tuberosa and I have not seen any specimens an- 

 swering the description of Asclepias decumbens. 



506. Asclepias incarnata var. pulchra (Ehrh.) Pers. There are a 

 few reports of this variety for Indiana but I am referring all of them to 

 pubescent forms of Asclepias incarnata L. The variety pulchra as now 

 known is confined to the Atlantic Coastal Plain. 



507. Asclepias speciosa Torr. Reported by Andrews from Monroe 

 County. This is a western milkweed and since Andrews did not report 

 Asclepias purpurascens, which is known to occur in Monroe County, I am 

 referring this report to that species.
