Excluded Species 1091 



576. Plantago indica L. Charles M. Ek found this species in 1935 in 

 dry, cindery ballast in the yards of the Pennsylvania Railroad at Kokomo, 

 Howard County, and also in Cass County, 4 miles northwest of Galveston 

 in ballast of the Pennsylvania Railroad. I am regarding this species as a 

 railroad migrant. 



Nat. of cent, and s. Eu. ; Pa., Ohio, Ind., Mich., and Iowa. 



577. Plantago elongata Pursh. Reported four times for Indiana but 

 doubtless all reports should be referred to Plantago pusilla. 



N. Dak. to Utah, southw. to Nebr. and Okla. 



578. Plantago sparsiflora Michx. This species was reported from 

 Clark and Jefferson Counties by the earlier authors before our manuals 

 made clear the distinction between the species, Plantago elongata and 

 Plantago pusilla. These reports should be referred, no doubt, to some other 

 species. A specimen collected by J. M. Coulter in Jefferson County is in the 

 herbarium of Wabash College and proves to be Plantago Rugelii. 



Coastal Plain, N. C. to Fla. 



579. Houstdnia canadensis Willd. (Houstonia clliolata Torr. of Gray, 



Man., ed. 7 and Britton and Brown, Illus. Flora, ed. 2.) This species has 

 been reported from Indiana thirteen times, but I believe all of these reports 

 should be referred to Houstonia longifolia. I have not seen a typical speci- 

 men of this species but our manuals say that at least the basal leaves of this 

 species are ciliate and Gray, Manual, ed. 7 says: "hirsute-ciliate." I have 

 seen no specimens which have this character or which look like the plant 

 shown in the colored plate in Torrey's Flora of New York. 

 Maine to N. D., southw. to W. Va. and Ark. 



580. Houstonia lanceolata (Poir.) Britton. This species was reported 

 by Daubenmire from Parke County, but he later referred the specimen to 

 Houstonia purpurea. 



Maine to 111., southw. to Okla. and Ala. 



581. Houstonia tenuifolia Nutt. Reported from Marion County by 

 Douglass. I have seen the specimen upon which this record was made and 

 it is a glabrate form of Houstonia longifolia Gaertn. 



E. Ohio to Va., southw. to N. C. and Tenn. 



582. GALIUM Aparine var. Vaillantii (DC.) Koch. This variety was 

 reported from Marshall County by Clark, who says that he found it in a 

 marsh. Since this species rarely grows in marshes, and since the habitat 

 is that of Galium labradoricum, I believe that he has confused the two. 



Ont. to B. C, southw. to Mo., Ariz., and Calif. 



583. Galium latifolium Michx. Andrews reported this species from 

 Monroe County but he did not report Galium lanceolatum, which should be 

 found in that county. Since the range of this species is in the Appalachian 

 Mountains, I believe that Andrews confused it with Galium lanceolatum. 



Mts. of Pa. to Ga. and Tenn. 



584. Galium Mollugo L. I reported this species from Marshall County 

 where I found several large colonies in a pasture field about a half mile
