WALNUT FAMILY 



Hicoria glabra now includes Carya microcarpa and Carya 

 porcitia of Gray. In the species as now constituted the fruit 

 varies greatly in form, being oval or globular as well as pyri- 

 form. The husk is always thin, smooth, often obscurely 

 winged, and divided into four unequal valves. The kernel at 

 first is sweet to the taste, but finally bitter. 



The number of leaflets varies from five to seven. In the 

 variety C. microcarpa the leaflets are five and the leaf as a 

 whole is a small but faithful copy of that of the Shellbark. 

 But other trees are found whose leaflets are oftener seven 

 than five. 



The bark is firm, close, usually divided by small fissures ; 

 it rarely exfoliates, but when it does the plates are not more 

 than five or six inches long.
