add other details of more or less importance. The following, then, is a 

 brief consideration of each species collected in White County — first the 

 Oaks, next the Hickories, a study of the Tippecanoe flora, followed by 

 the Willows and other species generally distributed over the county. 



2. The Oaks. 



The Oaks constitute the most important trees in White County in 

 point of utility and quality as well as in number of species in any one 

 genus represented, or as regards the number of individuals in the genus. 



Seventeen species of oaks have been reported for Indiana. This is 

 the number contained in both. Coulter's Flora and in Beam's 1911 Re- 

 port. The former, however, lists Quercus texana Buckley (Texan Red 

 Oak— Gibson, Posey, Knox— Dr. Schneck?) and Q. Phellos L. (Willow 

 oak — Gibson, Posey, Knox) — omitting Quercus Schneckii Britton 

 (Schneck's oak), and Q. ellipsoidalis E. J. Hill (Hill's oak). 



Quercus Schneckii Britton is a species yet in doubt (Deam). It 

 may be referable to Q. texana, but the new flora of Britton and Brown 

 says it "has been confused with Q. texana." It closely resembles Quercus 

 rubra L. and may supplant the latter to an unaware extent. Thus far 

 it has been reported from Bartholomew (Elrod) ; Gibson, Knox, Posey 

 and Vermillion (Schneck); Knox (Ridgway) ; Posey and Wells (Deam). 

 "It is believed that it is more or less frequent along the Wabash and its 

 tributaries," and so may occur in White County along the Tippecanoe 

 or southeastern part of the county. 



Quercus phellos L. references for Indiana have been changed to 

 Q. imbricaria Michx. (See Deam, 1911 Report, pp. 91-92.) 



Quercus ellipsoidalis E. .J. Hill was described (E. .J. Hill, Bot. Gaz. 

 27:204, 1899) after Coulter's Catalogue was published. 



Other oaks (Q. ilicifolia Wagn. and Q. nigra L.) have been reported 

 for our area, but for apparently sufficient reason have been referred to 

 other species, being in most cases variant forms. (1911 Report p. 91.) 



Ten out of the seventeen species reported for Indiana were found in 

 White County. Of the seven remaining species, Q. lyrata Walt., Q. 

 Michauxii Nutt., Q. falcata Michx., are quite restricted to the extreme 

 southwestern counties; Q. stellata Wang., Q. Prinus L., and Q. mary- 

 landica Muench., are southern or local; the distribution of Q. Schneckii 

 is discussed above.
