form and admit the difficulty of determination. It has been said to be 

 a variable form of Q. texana Sarg., not Buckley ?, possibly synonymous 

 with Q. Schneckii Brit. Q. borealis Michx., or Q. falcata Michx., or a 

 hybrid of these two have been mentioned, as has also Q. velutina Lam. 



My own idea coincides exactly with none of these. Q. borealis 

 Michx. does not occur in the State, so far as known. Not a single 

 reference to it is made in either Coulter's Catalogue or Beam's 1911 

 Report. Q. falcata Michx. has been reported from but three counties 

 in the State, viz., Gibson, Posey and Fountain, which last is somewhat 

 exceptional. Evidently the specimen under consideration is neither of 

 these or could possibly be a hybrid of them. Since more or less doubt 

 shrouds the texana-Schneckii determination from more than one stand- 

 point, and since these are the same or different species according to 

 different authors, I hesitate in applying either name, whether of the 

 same or different species. 



Q. velutina Lam. does not seem to be very conclusive. 



The supposed typical leaves, fruit, etc., used in various keys for 

 the same species many times, vary considerably. So in this case. The 

 leaves in this instance compare very favorably with those shown for 

 Q. rubra L., in Hough's Handbook of the Trees of the Northern States 

 and Canada. 



I have associated it most closely with Q. rubra L., being a rather 

 variable form of that species or a hybrid of it with velutina or coccinea. 

 I add this note from Hough's handbook: "Gray's Oak, Q. borealis Michx. 

 f., (also Q. ambigua Michx. f.), a large tree, occasionally found from 

 Ontario to Quebec to the mountains of North Carolina, bearing leaves 

 like Q. rubra L., and fruit like Q. coccinea. It is considered by some 

 a distinct species and by others, and probably more correctly, only an 

 aberrant form of Q. rubra L." 



3. The Hickories. 



With a Revised List for the State. 



The Hickories are very difficult of determination and authors are 

 by no means agreed. If I may venture upon a suggestion, it seems to 

 me that a more careful, thorough and extensive study in tlie field is
