Excluded Species 1035 



437. 1927) found 3-leaf forms of Maianthemum labeled Smilacina tri- 

 folia. This discovery suggests that plants reported as Smilacina trifolia 

 may have been wrongly determined. Buhl (Amer. Midland Nat. 16: 251. 

 1935) says Pepoon's reports lack confirming specimens. 

 Lab. to B. C, southw. to n. N. J., Pa., Ohio, and Mich. 



140. Convallaria majalis L. Lily-of-the-valley. This species was 

 reported as an escape in Lake County by Hill and as a doubtful escape in 

 St. Joseph County by Nieuwland. Andrew's report I am ignoring because 

 no data accompany the report. Since this species will persist for years 

 where it was planted about habitations although the buildings are removed, 

 authors must be careful to ascertain that the site was not that of a former 

 habitation. There is no proof that it has established itself anywhere by 

 propagation. 



Nat. of Eu., also from Va. to S. C. ; common in cultivation and prob- 

 ably escaped. 



141. Trillium cernuum L. Eames and Wiegand (Variations in Tril- 

 lium cernuum. Rhodora 25: 189-191. 1923) have shown that this species 

 belongs to the area east of the Allegheny Mountains and that our form of 

 the species is represented by Trillium cernuum var. macranthum which is 

 a northern form and is known so far in Indiana only from La Porte 

 and Porter Counties. 



142. Trillium erectum L. This species has been reported many times. 

 Specimens of Trillium Gleasoni with erect peduncles have, no doubt, been 

 confused with this species. The true Trillium erectum has much longer 

 filaments and a small, very dark purple ovary which should not be con- 

 fused with the larger, lighter red brown ovary of Trillium Gleasoni f. 

 Walpolei. Trillium erectum occurs south and east of our area. 



Ne. U. S., southw. in the Appalachians to Tenn. 



143. Smilax lanceolata L. Lanceleaf Greenbrier. This species was 

 reported to have been found along the railroad in Decatur County. This 

 may have been a wrong determination; if not, the plant was probably a 

 migrant because the range of the species is south of Indiana. 



Va. to Ark., southw. to Fla. and Tex. 



144. Smilax pseudo-china L. Longstalk Greenbrier. Pennell (Bull. 

 Torrey Bot. Club 43 : 410. 1916) has shown that this species should be re- 

 garded as a synonym of Smilax herbacea L. The few reports for it in 

 Indiana should be transferred to the last named species. 



145. Smilax Walteri Pursh. Coral Greenbrier. I reported this species 

 for Indiana on the authority of Schneck. Later I had an opportunity to 

 study the specimen and I found it to be Smilax rotundifolia L. It was also 

 reported from Posey County by Ridgway. Ridgway wrote me that he was 

 certain that he saw it on a sandy ridge near the Wabash River and north 

 of Coffee Bayou in Gibson County. I have searched this area for it but 

 most of the area has been cleared and if it was present at one time, it 

 has been exterminated. 



N. J. to Fla., and westw. to La.
