bitter skin, makes them worthless except for squirrels and other 
wild creatures.” CaTESBY’s figure of a single nut is not a very good 
one, and at one time led me to suppose that he had figured a nut of 
some form of C. ovalis, but there can be no doubt that his descrip- 
tion is that of C. cordiformis. In 1770 MUENCHHAUSEN (Hausv. 
5:181) called Juglans alba of Mitter the pignut among other 
names. MARSHALL in 1785 described C. cordiformis as Juglans 
alba minima and called it the pignut; but in 1787 WANGENHEIM 
called the Juglans glabra of MILLER the pignut and Juglans cor- 
diformis the bitternut, and these names appear to have been 
adopted by all later writers on these trees.

4. CARYA AQuaTica Nutt.—The water hickory has usually been 
considered an inhabitant of deep, long inundated river swamps, but 
toward the southern limits of its range in Florida and Texas it 
sometimes grows on the high sandy banks of rivers which are only 
occasionally overflowed, and in dry sandy soil at a considerable dis- 
tance from streams. The bark of trees in such situations is close, 
pale, and does not separate into the long, loosely attached scales 
which are characteristic of this tree when it grows in swamps, 
although the bark of very old trees growing on dry ground some- 
times shows a tendency to flakiness. The trees growing on dry 
ground have narrower leaflets and usually nuts of a different shape, 
without the longitudinal wrinkles peculiar to the nut of the water 
hickory, although some narrower-leaved trees bear nuts of the 
ordinary size and shape. These southern narrow-leaved trees are 
so distinct that they may be distinguished as 
CARYA AQUATICA var. australis, n. var.—Differing from the type 
in its narrower leaflets, in its smaller ellipsoidal fruit, pale red- 
brown nuts without longitudinal wrinkles, and in its close pale 
bark. Leaflets 9-11, lanceolate, acuminate, slightly falcate,
