1058 Excluded Species 



300. Gillenia trifoliata (L.) Moench. {Porter anthus trifoliatiis (L.) 

 Britt. of Britton and Brown, Illus. Flora, ed. 2.) Bowmansroot. Reported 

 from Clark County by Baird & Taylor and from the Lower Wabash Valley 

 by Schneck. The fact that both authors also reported Gillenia stipulata 

 supports their reports. Schaffner in his latest list of the plants of Ohio 

 carries the species but says: "No specimens." The record from Michigan 

 is based upon a report by N. W. Winchell who says this specimen was 

 deposited in the herbarium of the University of Michigan. J. H. Ehlers, 

 curator, writes me that Winchell's specimen is not there. In the absence of 

 specimens, the species is excluded. 



N. Y. to Mich., southw. to Ga. and Mo. 



301. Pyrus communis L. Common Pear. Nieuwland and Wilson re- 

 ported this species as escaping. I have seen a few small trees in woodland 

 and along fence rows but I do not believe those of the woodland in Indiana 

 are able to maintain themselves. The pear has had ample time to escape 

 in the state and if it has done so and is maintaining itself someone would 

 make mention of the fact. 



Nat. of Eu. and w. Asia ; often escaped and naturalized. 



302. Malus angustifolia (Ait.) Michx. Southern Crab. Reported 

 from Indiana but since this is a southern species our records must belong 

 to some other species. 



Va. to Fla. and Miss. 



303. Malus pumila L. Common Apple. This species has been reported 

 from several counties but I am excluding it because no author says that it 

 is maintaining itself. I have seen fruiting specimens along fences and in 

 woodland but search failed to show any offspring. In St. Joseph County 

 about 6 miles southwest of South Bend I saw possibly 25 trees in moist, 

 sandy soil in the Rupel woods where it joined a marl, treeless swamp. 

 Since the trees were approximately the same size the indications were that 

 they had not reproduced and that they might have all been planted there. 

 In Elkhart County on the north side of Simonton Lake there is a small 

 colony of trees but there is no evidence that any of them were self sown. 

 Since during the past years millions of apple cores have been cast aside 

 along roadsides and fences and in public grounds and woodland, it is sur- 

 prising that we do not find many more "wild apples" than we do. Sufficient 

 time has elapsed for someone to have found it where it is maintaining itself 

 but I find no such record. I believe it is best to treat as occasional 

 escapes species of this kind where millions of seed are scattered through- 

 out the state on all kinds of soils and no reproduction follows. 



Nat. of Eu. and w. Asia; cultivated since ancient times. 



304. S6RBUS Americana Marsh. The first specimen of this genus which 

 I found was collected in La Porte County and I named it this species. 

 Nieuwland, upon my authority, reported it in a list of "Local plants." 1 

 now refer the specimen to Sorbus Aucuparia L. 



Newf. to Man., southw. to N. C. and Mich.
