Carya Juglandaceae 371 



that most of the reports of it from the northern part of the state should 

 be referred to Carya ovalis or some of its many forms. One or more trees 

 grow on the high sand bank of the north side of Lake Ann, about 5 miles 

 northeast of Fremont, Steuben County. E. J. Palmer has verified the 

 determination. My record from Delaware County I am now referring to 

 Carya ovalis variety. This species and the next are entirely distinct, but 

 it is impossible to name correctly herbarium specimens which are incom- 

 plete, immature, or without field data. In collecting specimens of these two 

 species, it is desirable that a note be made whether the bark of the trunk 

 and principal branches is tight or somewhat scaly and whether the surface 

 of the fruit is smooth or granular. The prevailing number of leaflets also 

 should be recorded. Fruiting specimens should not be collected until 

 mature, usually after the first of October. Flowering specimens should 

 always be accompanied by a fruiting specimen from the same tree. 



6a. Carya glabra var. megacarpa Sarg. (Sargent. Bot. Gaz. 66: 244. 

 1918.) This variety is distinguished from the type by its larger obovoid 

 fruit, 2.5-4.5 cm long and by the husk, 2.5-3 mm thick. I have a specimen 

 from Franklin County given this varietal name by Sargent. 



Infrequent to common on hills with black and white oak. It is especially 

 common in the knobstone area of the state.

7. Carya ovalis (Wang.) Sarg. (Carya microcarpa Nutt. in part, and 

 Hicoria microcarpa (Nutt.) Britt.) Sm all-fruited Hickory. Map 764. 

 All of the varieties are shown on the map with the species. Found through- 

 out the state but infrequent to rare south of the lake area except on some of 

 the sandy ridges of the southwestern part. In the lake area it is usually 

 frequent to common on clay and sandy ridges with black and white oak. 



This species is extremely variable in the character of the bark and in the 

 shape of its fruit and nuts. The bark is generally scaly on the principal 

 branches and on the trunk except near the base of the tree. It is usually 

 not thick but I know of one specimen in Lagrange County that has very 

 thick and tight bark. The nuts of this tree are almost cubical, but otherwise 

 the tree is typical Carya ovalis. The nuts vary from ellipsoidal to obovoid, 

 with the base acute or rounded, the apex acute, rounded or obcordate, little 

 or strongly compressed, the surface from nearly smooth to strongly ridged 

 or somewhat roughened.

7a. Carya ovalis var. odorata (Marsh.) Sarg. This variety is separated 

 by the resinous odor of the inner surface of the fresh husk, but I have not 

 been able to test this character. I am referring to this variety my speci- 

 mens which Sargent so named. My specimens are all from the extreme 

 northeastern part of the state, from Allen, Grant, Lagrange, Steuben, and 

 Wells Counties.
