species ; excepting its thinner-shelled, generally smaller nut, I 

 have been entirely unable to distinguish characters which will 

 always separate it from the next. Professor Sargent has united 

 it with the Eastern Shagbark, referring to it in the Forestry Re- 

 port of the loth Census, p. 133, as "a form with small, thin 

 shelled nuts." I am very confident that its alliance is not with 

 H. ovata. The mistake may have arisen from the fact that in 

 the Herbarium of the Philadelphia Academy, a label of Nuttall's 

 has been misplaced and pasted alongside of a flowering twig of 

 H. ovata. But his original description, his authentic fruiting 

 specimens both at Philadelphia and Kew, and the figure of the 

 plant in his Sylva, prove that its affinities are not with the Shag- 

 barks, but rather as I have placed it. 



X JNut larger, thick-shelled ; leaflets 5 to g. 



(7.) H. GLABRA (Mill). {Juglans glabra, Mill., Gard. Diet, 

 No. 5, (1759); Juglans porcina,W\c\\yi. f, Hist. Arbres Amer., 

 i., 206, t, 9, (18 10); Cary a glabra, Torn; Carya porcina, Nutt.) 

 The size of the nut is given in Gray's Manual, (p. 449), at from 

 1 1^ to 2 inches long. While they do actually grow as large as 

 this in the Southern States, the more correct figures for those of 

 New York and the Middle States generally is not more than 

 half these dimensions. 



JJJNut smooth, very thin-shelled, with a very bitter seed; leaflets 7 tog, 

 ovate lanceolate, minutely glandular, pubescent beneath. 



(8.). H. MINIMA (Marsh). Juglans alba minima^ Marsh., 

 Arb. Amer., p. 68,(1785); Juglans ainara, Michx., f. Hist. 

 Arbres Amer., i., 177, t. 4, (1810); Carya amara, Nutt.) The 

 name minima applied by Marshall evidently refers to the size of 

 the leaflets, which, as a general thing, are smaller at maturity 

 than those of any other Northern species. 



JttJNut tliin-shelled, angular; seed bitter; leaflets 7 to 13, lanceolate- 

 acuminate, somewhat falcate and inequilateral, slightly pubescent below. 



(9.) H. AQUATICA, (Michx., f) {Jnglans aguatica,M\chK.,i., 

 Hist. Arbres Amer., i., 182, t. 5 ; Carya aqnatica, Nutt.) The 

 northward range of this species may now be increased to Mob 

 Jack Bay, Virginia, (Leggett.)
