1022 Excluded Species 



is north of Indiana, I am referring all of our records to Lycopodium 

 flab elli forme (Fern.) Blanchard. 



Newf. to Alaska, southw. to n. Ont, n. Mich., n. Wis., and n. Wash. 



17. Lycopodium lucidulum var. occidentale (Clute) Wilson. (Rhodora 

 34: 170. 1932.) (Lycopodium porophilum Lloyd & Underwood (Bull. Tor- 

 rey Bot. Club 27: 150. 1900) in part but not as to type specimen and Lyco- 

 podium lucidulum var. porophilum (Lloyd & Underwood) Clute in part.) 

 Buhl refers Peattie's report from the Indiana Dunes to the species. It 

 grows in moist pockets in sandstone cliffs and on ledges. 



Mich., Minn, and Wis. 



18. Lycopodium tristachyum Pursh. This clubmoss was reported 

 from the Indiana Dunes by Peattie. Since there are no confirming speci- 

 mens, and the range of the species is to the north of Indiana, I am exclud- 

 ing it. 



Newf. to Lake Superior, southw. to Del. and in the mts. to Ga. ; also 

 in Eu. 



19. Isoetes Braunii Durieu. In Crawford County, in a small pond in 

 the corner of a field on the Nathan Bowman farm, about 5 miles south of 

 Marengo, and a half mile east of the Pilot Knob School, I collected a 

 quillwort that was placed in this species by a specialist. Later my speci- 

 mens were named Isoetes Engelmanni A. Br. by Norma Pfeiffer in her 

 monograph. I reported this specimen as /. Braunii (Proc. Indiana Acad. 

 Sci. 1916: 315. 1917) but now refer it to /. Engelmanni. 



North America. 



19a. Isoetes foveolata A. A. Eaton. A specimen from an old stream 

 bed in a low woods in Harrison County, 1 mile east and 4 miles south of Pal- 

 myra, was named Isoetes foveolata by an authority. Later the same spec- 

 imen was referred by Norma Pfeiffer to Isoetes Engelmanni A. Br. In the 

 meantime I had reported it as I. foveolata (Proc. Indiana Acad. Sci. 1916: 

 315. 1917). I am now referring these specimens to I. Engelmanni. 



N. H. 



20. Pinus echinata Mill. Shortleaf Pine. It is doubtful whether this 

 species occurs in Indiana and until it is definitely established that it is 

 native, all references to it should be referred to Pinus virginiana. It was 

 planted about 1917 on the old Schlamm farm in the Clark County State 

 Forest among Pinus virginiana. This statement is made to prevent its 

 being reported in the future as a native plant. An old timber buyer told 

 me that in the vicinity of Borden, Clark County, there were two kinds 

 of "scrub" pines but in a search for them he failed to find the two species 

 for me. 



Long Island, N. Y., W. Va., sw. 111., s. Mo., se. Okla., southw. to Fla. 

 and Tex. 



21. Pinus resinosa Ait. Norway Pine. This pine has been reported as 

 an escape in Wabash County, but there is no verifying evidence. 



Mass., Mich, to Minn, and northw.
