ble Piperacese, from which, however, they differ materially in other points. 
Blume rejects Nageia because of its opposite leaves and albuminous seeds, 
without, however, stating to what order that genus really belongs. Comptonia 
he thinks the same as Myrica. 
Geography. Found in the cold parts of Europe and North America, the 
tropics of South America, the Cape of Good Hope, and India. 
Properties. Aromatic shrubs, or trees of considerable size. Comptonia 
asplenifolia possesses astringent and tonic properties, and is much used in the 
domestic medicine of the United States, in cases of diarrhoea. Barton, 1. 224. 
The root of Myrica cerifera is a powerfid astringent, and wax is obtained in 
great abundance from its berries. The fruit of Myrica sapida is about as large 
as a cherry, and, according to Buchanan, is a pleasant acid and eatable in 
Nipal. Don, p. 56. It has a pleasant, refreshing, acidulous taste. Wall.

Order CXXIX. JUGLANDACE^. The Walnut Tribe, 
Juglandea:, DC. Theorie, 215. (1813) ; Kunth in Ann. des Sc. Nat. 2. 343. (1824) ; 
Blume FI. Jav. ; Bartl. Ord. Nat. 397. (1830). 
Essential Character. — Flowers unisexual, usually monoecious. in the males 
oblique, membranous, irregularly divided, attached to a single bract ; in the females supe- 
rior, with 4 divisions, which are sometimes permanent and leafy. Petals in the males 0 ; 
in the females occasionally present, and 4 in number, arising from between the calyx and the 
styles, and cohering at the base. Stamens indefinite, (3-36), hypogynous ; //amends very 
short, distinct; anthers thick, 2-celled, innate, bursting longitudinally. Disk 0. Ovary 
inferior, incompletely 2-4-celled ; ovule solitary, erect ; styles 1 or 2, and very short, or 
none ; stigmas much dilated, either 2 and lacerated, or discoid and 4- lobed. Fruit dru- 
paceous, 1 -celled, with 4 imperfect partitions. Seed 4-lobed; embryo shaped like the seed; 
albumen 0 : cotyledons fleshy, 2-lobed, wrinkled ; radicle superior. — Trees. Leaves alter- 
nate, unequally pinnated, without pellucid dots or stipules. Flowers racemose. 
Affinities. These have usually been mixed with Terebintacese, to which 
they, however, do not appear so closely allied as to Cupuhferse, with which 
they accord in their unisexual flowers, and superior calyx, and, in the case of 
the genus Synsedrys, in their lobed embryo. Among apetalous orders, their 
pinnated resinous undotted leaves particularly distinguish them. 
Geography. Chiefly found in N orth America ; a few are East Indian; 
one species, the common Walnut, is a native of the Levant and Persia; 
another, of Caucasus ; and a third, of the West India Islands. 
Properties. The seed of the Walnut is esteemed for its sweetness and 
wholesome qualities. It abounds in a kind of oil, of a very drying nature. 
The rind of the fruit, and even the skin of the kernel, are extremely astringent. 
Juglans cathartica or cinerea is esteemed anthelmintic and cathartic ; the fruit 
of several kinds of Hickory is eaten in America. The timber of all is valuable ; 
that of J. regia for its rich deep brown colour when polished, and that of Carya 
alba for its elasticity and toughness.
