1078 Excluded Species 



476. ProserpinAca palustris L. According to Fernald and Griscom 

 (Rhodora 37: 177. 1935) all reports for this species in Indiana should be 

 referred to the varieties which will be found in the regular text. The species 

 belongs to the Coastal Plain of the southeastern United States. 



477. Hydrocotyle rotundifolia Roxb. In the herbarium accessions 

 of the New York Botanical Garden published in the Journal of the New 

 York Botanical Garden 23: 184. 1922, there is the following: "1 specimen of 

 Hydrocotyle rotundifolia from Indiana (Given by A. A. Hansen)." There 

 are no other data. This is an Asiatic species and has been reported as es- 

 tablished in lawns in Evansville. 



478. Spermolepis patens (Nutt.) Robinson. This species was found 

 June 24, 1898, by L. M. Umbach along the railroad near Miller and 

 first reported for him by Coulter & Rose in Contr. U. S. Nation. Herb. 7 : 

 72. 1900. It was later reported by Pepoon who says : "B. & 0. Ry. at cross- 

 ing of the Little Calumet River, northeast of Miller; common locally. 

 (Umbach, Pepoon.)" I visited this place about July 1, 1930, and I was 

 not able to find it. This species should no doubt be regarded as a migrant 

 since it is found along a railroad out of its range and has not been able to 

 spread or probably to maintain itself. 



479. Aethusa Cynapium L. Fool's Parsley. This species was re- 

 ported by Erlanson for Grimes (Proc. Indiana Acad. Sci. 1923: 149. 1924) 

 as having been found in a ravine in Putnam County. The specimen which 

 was reported has been located in the herbarium of DePauw University and 

 it is Osmorhiza Claytoni, so the species must be excluded. Aethusa Cyna- 

 pium is a poisonous plant naturalized from Europe. 



N. S. to Pa., Minn., and Ont. 



480. Thaspium pinnatIfidum (Buckley) Gray. This species was re- 

 ported from Marshall County by Clark. This determination, no doubt, 

 should be referred to the narrow leaflet form of Thaspium barbinode. 



Ky. to N. C. and Ala. 



481. Nyssa aquatica Marsh. This species has been reported by several 

 authors and all of the reports should be referred to Nyssa sylvatica except 

 those of Ridgway and Schneck which may be correct, but there is no speci- 

 men. The cypress swamps in Knox County furnish the proper habitat for 

 the species and it may have occurred there. 



Many years ago I questioned Michael Catt, 83 years old at that time, 

 who had lived for about 75 years on the border of the cypress swamp in 

 Knox County and he told me that he was positive that the tupelo gum was 

 an occasional tree in the cypress swamp west of Decker. In my botanical 

 experience I have met several people who were positive that this species 

 existed, but upon investigation, I found all reports to be erroneous. In 1931 

 I found an old timber buyer who was positive that it occurred in Goose 

 Pond in Gibson County and when he showed me the tree, it proved to be 

 Populus heterophylla. With conflicting reports, it is best to exclude it. 



Along the Atlantic coast from Va. to Fla., west through the Gulf States 

 to Tex., and northw. in the Mississippi Valley to 111.
