Contributions to the Flora of Indiana, No. IV. By Stanley Coulter. 



The preceding papers in this series are those entitled Saxifragacea' of Indiana 

 (Proc. Ind. Acad. fSci., 1894, pp. 103-107): A Preliminary List of Plants Growing 

 in the Vicinity of Washington, Daviess County (Proc. Ind. Acad. Sci., 1895, pp. 

 169-182); Noteworthy Indiana Phanerogams {Froc. Ind. Acad. Sci., 1895, pp. 183- 

 1981. The notes are incidental to the preparation of the catalogue of the flora of 

 the State, and are in a measure supplemental to that work. 



Many plants which were originally included in this contribution have been 

 omitted, because of their inclusion in much fuller detail than I could possibly 

 have given in the papers of Messrs. \V. S. Blatchley and Robert Hessler, M. !>., 

 published in these proceedings. With the exception, therefore, of a few forms 

 to which I desire to call attention, the body of this paper concerns the compositai 

 of the State, with special reference to their distribution. 



Coptis Irifolia Salisb. Mr. Van Gorder reports this plant as very abundant 

 in certain localities in both Noble and DeKalb counties. So far as has come to 

 my knowledge, this is the only record of the plant in the State authenticated by 

 herbarium specimens. Its range and habits of growth would indicate its pres- 

 ence in the swamp regions of our northern counties. 



Ailanthus glandulosus Desf. This tree, not as yet included in the lists of the 

 forest trees of the State, seems to have become thoroughly naturalized, and is 

 entitled to a place in our flora. In Jefferson county it has escaped from cultiva- 

 tion and covers entire hillsides, notably in the vicinity of Madison and Hanover 

 college. The growth is so dense and rapid as to make it a somewhat doubtful 

 acquisition. A thicket of Ailanthus in full foliage gives a very fair idea of the 

 appearance of semi-tropical undergrowth. The tree should be included in the 

 flora of the State. 



Sullivantia Ohionis Torr. and Gray. This form, the distribution of which I 

 limited (Saxifragace(p of Indiana, Proc. Ind. Acad. Sci., 1894, p. 104) to a single 

 station at Cliffy Falls, Jefferson county, must have an added station in Clark 

 county. The determination of Dr. C. R. Barnes, questioned in that communica- 

 tion, has been verified by abundant specimens found among the duplicates in 

 Purdue university. The Clark county station is of the same general, character 

 as that at Clifty Falls, the plant clinging to the vertical sides of moist limestone 

 cliffs, by no chance seeming to leave this apparently barren position for the 

 deeper and richer soils surrounding. The plant in our region may be considered 

 as the most characteristic of the limestone cliffs.
