In that memorable day when leaving the Samhar, or low flat parched country which forms the sea-coast of Abyssinia, and turning westward, we came to the foot of that stupendous mountain Taranta, which we were to pass in order to enter into the high land of Abyssinia, we saw the whole side of that prodigious mountain covered from top to bottom with this beautiful tree. We were entering a country where we daily expected wonders, and therefore, perhaps, were not so much surprised as might have been supposed at so extraordinary a sight. The fruit was ripe, and being carried on the top of the branches, the trees that stood thick together appeared to be covered with a cloth or veil of the most vivid crimson colour. The first thing that presented itself was the first shoot of this extraordinary tree. It was a single stalk, about six inches measured across, in eight divisions, regularly and beautifully scolloped and rounded at the top, joining in the centre at three feet and a half high. Upon the outside of these scollops were a sort of eyes or small knots, out of every one of which came five thorns, four on the sides and one in the centre, scarce half an inch long, fragil, and of no resistance, but exceedingly sharp and pointed. Its next process is to put out a branch from the first or second scollop near the top, others succeed from all directions; and this stalk, which is soft and succulent, of the consistence of the aloe, turns by degrees hard and ligneous, and, after a few years, by multiplying its branches, assumes the form as in the second plate. It is then a tree, the lower part of which is wood, the upper part, which is succulent, has no leaves; these are supplied by the fluted, scolloped, serrated, thorny sides of its branches. Upon the upper extremity of these branches grow its flowers, which are of a golden colour, rosaceous, and formed of five round or almost oval petala; this is succeeded by a triangular fruit, first of a light green with a slight cast of red, then turning to a deep crimson, with streaks of white both at top and bottom. In the inside it is divided into three cells, with a seed in each of them; the cells are of a greenish white, the seed round, and with no degree of humidity or moisture about it, yet the green leaves contain a quantity of bluish watery milk, almost incredible.
