In the uninviting landscape a tufty, straggling grass, like living hay, often raised on little mounds, with bald places between, thinly strewed with bits of quartz and sandstone, replaces the tall luxuriant herbage of the maritime plain, and the arboraceous and frutescent produce of the mountains. The dryness of the climate, and the poverty of the soil, are displayed in the larger vegetation. The only tree of considerable growth is the calabash, and it is scattered over the country widely apart. A variety of frankincense overspreads the ground; the bark is a deep burnished bronze, whitened above with an incrustation, probably nitrous, that resembles hoar-frost; and the long woody twigs are bleached by the falling off of the outer integuments. The mukl or bdellium tree rises like a dwarf calabash from a low copse. The Arabs declare this produce of Ugogo (_Balsamodendron Africanum?_), to be of good quality. Rubbed upon a stone and mixed with water it is applied with a pledget of cotton to sluggish and purulent sores; and women use it for fumigation. The Africans ignore its qualities, and the Baloch, though well acquainted with the bdellium, gugal, or guggur, in their own country, did not observe it in Ugogo. The succulent plants, cactus, aloe, and euphorbia, will not burn; the air within them expands with heat, and the juices gushing out extinguish the flame. Amongst various salsolæ, or saltworts, the shrub called by the Arabs arak, the Capparis Sodata of Sindh and Arabia, with its currant-like bunches of fruit, is conspicuous for its evergreen verdure; the ragged and stunted mtungulu rains its apples upon the ground; and the mbembu, in places sheltered from the sun, bears a kind of medlar which is eagerly sought by the hungry traveller. The euphorbiæ here rise to the height of 35 or 40 feet, and the hard woody stem throws out a mass of naked arms, in the shape of a huge cap, impervious to the midday sun.
