36 Dr. Hancock on 
THE JURIBALI. 
REMARKS ON THE JURIBALI, OR Eur1BaLt, (so called by the 
Natives,) a Febrifuge Bark Tree of Pomeroon. By 
Joun Hancock, m.D., Fellow of this Society, Honorary 
Member of the Society of Arts of Scotland, &c. 
Tuis tree is found in the forests not far distant from the coast. 
It is small, seldom exceeding thirty feet in height, and eight or 
ten inches in diameter at the base. It belongs to the eighth 
class and first order of the sexual system of Linnzus, and to 
the natural family of Meliacez of Jussieu. The calyx is very 
small, of one leaf, entire. ‘The corolla consists of four pe- 
tals, lance-ovate, white, spreading. The nectarium is a mo- 
nophyllous, bell-shaped tube, eight-toothed, bloated or 
inflate, bearing the stamina in its clefts or notches: this part 
is described by several authors as the filaments united. ‘The 
stamina are without filaments. The anthers are eight in 
number, ovate, erect, seated upon the mouth of the necta- 
rium. The germ is obtusely conic and pubescent. The 
style is very short, bearing capitate, or rather coronate, 
stigmata. The pericarpium is a capsule, ovate, one-celled, 
trivalved, the valves bearing rudiments of septa at their 
extremities: it contains a single seed, which is roundish, 
black, crowned with a trifid wing, arillate on one side only; 
it is veined, and resembles the nutmeg in shape, but is only 
half its size, with a fleshy albumen and foliaceous cotyle- 
dons. ‘The fiowers are numerous, on long, lax, divaricate 
panicles. 
Nature has distinguished this tree in a very remarkable 
manner ; for it may be truly said to bear two distinct kinds of 
leaves, the stipules being, at certain seasons, so developed as 
to be not unfrequently confounded with the common leaves 
of the tree, but are distinguished by their shape and position. 
They are placed in pairs, and scattered along the branches; 
ear shaped or rounded and varied, obtuse and petiolate. 
The common, or proper leaves, are alternate, oblong, 
pointed; they are scattered, without much order, on the 
branches; the petioles are short, compressed, and channelled. 
The bark is rough and gray externally, and, on peeling it 
from the tree, the epidermis scales off, and leaves the true 
bark of a smooth red surface. Its odour is peculiar, some- 
what like that of tea-leaves. The wood of the trunk is dense 
and whitish; that of the branches somewhat coloured, and
