Derivation. The genus Broussonetia was so named in honour of M. P. N. V. Broussonet, a French naturalist, who wrote 
numerous works on natural history. 
Generic Characters. Flowers unisexual ; those of the two sexes upon distinct plants. Male flowers in 
pendulous cylindrical catkins ; each flower in the axil of the bractea. Calyx shortly tubular, then 4- 
parted. Stamens 4, elastic. Female .flowers in peduncled, axillary, upright, globular heads. Calyx 
tubular, its tip with 3 4 teeth. Ovary within an integument that arises from the bottom of the calyx. 
Style lateral, prominent. Fruit club-shaped, proceeding from the bottom of the calyx, and extended 
much beyond its tip ; and consisting of the integument in which the ovary was enclosed, and now 
becomes very juicy ; and of a 1-seeded oval utricle, with a crustaceous integument, and enclosed 
within this juicy integument. Du Hamel, Trait e de Arbres. 
I HE genus Broussonetia was constituted by L'Heritier from the 
Morus papyri/era, and is said to comprise but one species, native 
of Japan, and the Islands of the Pacific Ocean. It consists of a 
vigorous-growing shrub or low tree, with large-lobed, hairy leaves, 
variously shaped, and differing so much from each other on the 
male and female plants, that they might be easily taken for dis- 
tinct species. 
To the same natural order belong the fustic-trees of the tropics, which are 
more nearly allied to this genus than to morus. They differ from the true mulber- 
ries by having the female catkins globular, the flowers distinct, calyx scariose, 
4-parted ; the sepals unequally obovate, obtuse, the ovary ohovate-compressed ; 
the style single, terminal, smooth, filiform, and flexuose ; and the fruit a globu- 
lar, compound berry or syncarpe ; whereas the true mori have double styles and 
stigmas, and oblong fruits. There are several kinds of fustic-trees, which 
might be formed into a peculiar group, from their baccate seeds. The true fustic 
of dyers, (Morus tinctoria,) is a large tree, sixty feet in height, bearing sweet, 
edible fruit, about the size of a nutmeg, and is a native of Central America, Yuca- 
tan, Cuba, Jamaica, &c. The whole plant abounds in a slightly glutinous milk, 
of a sulphureous colour. The wood is yellow, and is much used in dyeing, for 
which purpose it is chiefly imported into Europe and the United States, under 
the name of fustic-wood. There is a variety of this species, called Bastard Fustic, 
a tree smaller in stature, and less valuable as a dye, and is found from Yucatan 
to the southern parts of Florida and the Bahama Islands.
