1054 Excluded Species 



Putnam County, June 4, 1911. I have a specimen which E. L. Greene col- 

 lected in 1917 in ballast along the railroad in Plymouth, Marshall County. 

 These are the only records, and the species is obviously a railroad migrant 

 which does not maintain itself. 



Ont., Man., B. C, and Alaska, southw. to Kans., Colo., and Nev. ; adven- 

 tive farther east. 



275. LobulAria maritima (L.) Desv. (Koniga maritima (L.) R. Br. 

 of Britton and Brown, Illus. Flora, ed. 2.) Sweet Alyssum. Reported as 

 an escape in a few counties but it does not persist. 



Nat. of Eu. ; Vt. to Pa. and on the Pacific coast. 



276. Cleome serrulata Pursh. Pink Cleome. Schneck found this 

 species in the Lower Wabash Bottoms but he left no data. I found a single 

 specimen on the fill of the bridge across the wet prairie about 4 miles 

 southwest of Bluffton, Wells County. It was far removed from a habitation 

 but I believe it was introduced in dumpings along the fill. 



111., Minn, to Sask., southw. to Mo., N. Mex., and Ariz. 



277. Cleome spinosa L. Spiderflower. This species has been reported 

 three times as a garden escape but not since 1904. In 1933 I found three 

 specimens about a hundred feet apart in a wet pasture field on the east 

 side of the C. E. & I. Railroad about 4 miles north of Decker, Knox 

 County. This area was formerly a part of a great cypress swamp which 

 has been drained and is now farmed and is more than a quarter of a mile 

 from the nearest habitation. Since there is no conclusive evidence that it 

 has become established, it is best to continue to regard it as an escape. 



Nat. of tropical America ; in waste places from s. N. Y. to Fla., westw. 

 to Ind., Ark., and La. 



278. Podostemum ceratophyllum Michx. Riverweed. This plant has 

 been reported by Peattie as rare in the Grand Calumet and Little Calumet 

 Rivers. I have asked two careful collectors to search for it in these streams 

 but they did not find it. I have looked for it in the Tippecanoe and Eel 

 Rivers but I did not find it. If Peattie collected specimens I do not know 

 where they are located. There is no specimen in the Field Museum, and it 

 seems best to exclude the species. 



N. B. to Ont. and Minn., southw. to Ga. and Ala. 



279. Sedum Nevii Gray. In discussing the distribution of this species, 

 Howe (Torreya 5: 115. 1905) says: "Collected originally in southwest- 

 ern Virginia, but since found to extend to Indiana." This is the only 

 reference I have found which ascribes it to Indiana. Neither of our man- 

 uals include Indiana in its range, so it may be safely omitted from our 

 flora. 



Va. to 111. and Mo., southw. to Ala. 



280. Sedum pulchellum Michx. Texas Stonecrop. Ball reported this 

 species from Lake County in 1884. Since this is far north of the natural 

 range of the species, it must have been a garden escape. I have had it in 

 cultivation for many years and it abundantly reseeds itself each year and
