=Betula lénta= Linnæus. Black Birch. This species has been reported for Indiana as occurring in Fulton, Gibson, Miami, Noble, Posey, St. Joseph and Steuben Counties. Sargent[84] says: "This species has until recently been badly misunderstood. The range of the species is southern Maine to northwestern Vermont, eastern Kentucky, and south to Delaware and along the Appalachian Mountains to northern Georgia and Alabama." No doubt all of the Indiana records should be transferred to _Betula lutea_, except the Gibson and Posey County record which may be _Betula nigra_. =Castanea púmila= (Linnæus) Miller. Chinquapin. This species was given a place in our flora in Coulter's catalogue upon the authority of Sargent, Ridgway and Schneck. Ridgway, in giving an additional list of the trees of the Lower Wabash Valley[85] says: "There is some doubt as to No. 16 _Castanea pumila_, which is given on Prof. Sargent's authority; but there is a possibility of an error having been made from the circumstances that the name 'chinquapin' is in that region almost universally applied to the fruit of _Quercus Muhlenbergii_." The Posey County record was based on a specimen in Dr. Schneck's herbarium, which proves to have been taken from a cultivated tree near Poseyville. =Quercus ilicifòlia= Wangenheim. Bear Oak. This species is credited to our flora by Will Scott in his ecological study of "The Leesburg Swamp" in Kosciusko County, published in the Indiana Academy of Science, 1905, page 225. In a reply to an inquiry addressed to him he says no herbarium material was preserved. This ecological work was done during the summer months while working at the biological station at Winona Lake. In a footnote in this paper we are informed that for the identification of the trees listed, Apgar's Trees of the Northern United States was used. In this key to the trees, _Quercus velutina_ (Black Oak) is given only as a variety of _Quercus coccinea_ (Scarlet Oak), and the distinction between _Quercus velutina_ with its many formed leaves, and _Quercus ilicifolia_ is not made apparent. In view of the fact that the natural habitat of _Quercus ilicifolia_ is sandy barrens and rocky hillsides and its western range is eastern Ohio, it is believed what Mr. Scott had in hand was a variable form of _Quercus velutina_, which is frequent in that vicinity. The evidence is not encouraging enough to include it.
