ALOE ARBORESCENS. 47 
scarious, three-cornered, three-celled, three-valved, with a loculicidal dehiscence. Seeds numerous, in two rows, 
roundish or angular. (Lsndiey.) 
Specir. Cuar.—Stem woody, simple, cylindrical, short. Leaves fleshy, amplexicaul, first spreading, then ascend- 
ing; lanceolate, glaucous green, flat above, convex below, armed with hard, distant, reddish spines, perpendicular to 
the margin, a little mottled with darker colour; the parenchyma slightly coloured brown, and very distinct from the 
tough, leathery cuticle. Scape axillary, glaucous reddish, branched. Spzke cylindrical ovate. Flowers at first erect, 
then spreading, afterwards perpendicular, yellow, not longer than the stamens. (Lzndley.) 
According to Pereira, this species is a native of the East Indies and Barbary, and is cultivated in the West 
Indies, Italy, Sicily, and Malta. It yields Barbadoes Aloes, and perhaps some of the varieties of hepatic. Beneath 
the epidermis of the leaves, in peculiar parallel vessels, is found a brownish-yellow, bitter, resinous juice. 
Barbadoss Aloes is procured in the month of March. It is of several qualities, according to the mode of prepa- 
ration. The best is prepared by boiling the juice, which has exuded from the cut leaves, in kettles, to the proper 
consistence. It is usually poured into gourds or calabashes, and hence sometimes is called Gourd Aloes. They weigh 
from 60 to 70 pounds. Inferior kinds are prepared by the expression of the juices from the bruised leaves and evapo- 
ration, or by decocting the leaves. 
It varies in colour from a dark brown or black to a reddish brown or liver colour, which diversity is apparent in 
the same gourd. Its fracture is glossy or dull. It has a very disagreeable odour, and an intensely bitter taste. 
This kind of Aloes is a warm cathartic, acting upon the lower intestines, more especially the colon and rectum. 
This, or other kinds of the drug, enters into numerous preparations.

This plant is an inhabitant of the Cape of Good Hope, and a part of the Aloes of commerce is said to be collected 
mit. The leaves abound in the peculiar bitter juice.
