seams, which, at complete maturity, open throughout their whole length for 
the escape of the nut. The shell is thick, and of a yellowish hue; while that 
of the C. alba is white. The wood is of the same quality as that of C. alba: 
it is brought to market in Philadelphia, but only in very small quantities. 
The Gloucester hickory, Michaux considers to be a variety of this species ; 
and he also mentions another, growing in the gardens of the Petit Trianon, 
and to which he thinks the specific name of ambigua might be given; as he is 
doubtful whether it is a variety or a species. In the Horticultural Society’s 
Garden, and in the collection at Messrs. Loddiges’s, and at White Knights, 
there are plants marked Carya sulcata, or Juglans lacinidsa, which are dis- 
tinguishable from all the other species of Carya, by their very large leaf- 
lets, which, in autumn, die off sooner than those of any of the other sorts. 
Nuts of this species are, in London, Is. 6d. a quart.
