GENERA JUGLANS, FRAXINUS &C. 245 



Marshall and Miller. I have observed 3, 5, 

 7 leaflets.* 



5. Juglans amara. This is J. cinerea of 

 Walter, but I cannot decide whether also 

 of Linnaeus. It is universally known in this 

 country by the name of Bitter-nut, Hog-hickery, 

 white Hickery. Marshall calls it J. alba minima. 

 It is easily distinguished by its compressed leaf 

 stalk and the leaflets, which are 7 — 12 and 

 smaller ; but more particularly by its rough and 

 furrowed nut, containing a bitter kernel. Juglans 

 cordiformis Wangenh. appears to be different 

 from J. amara ; but the description and figure 

 of Juglans sulcata Willd.-j- agree very well with 

 it. The wood of this species is not esteemed so 

 good fuel as that of the two former. \ 



• J. compressa : foliolis seprenis oblongo-lanceolatis acuminatis subtus 

 pubescentibus mollibus, nucibus obliquis compressis. 



f Willdenow's Eerlinische Baumzucht (description of the trees in 

 the neighbourhood of Berlin) Berlin 1796. 8. pag. 145. tab. 7. 



i J. sulcata : foliolis subseptenis lanceolatis acuminatis subtus pubescenti- 

 bus, fructibus subrotundis quadrisulcatis. 

 This appears not to be J. cinerea L. though it has sometimes ji leaflets.
