Our day’s botanising on the rocks near Seksaoua was successful beyond our expectations. Many conspicuous plants peculiar to Marocco were here seen for the first time. Several of these had been gathered by M. Balansa during the four days which he passed in the adjoining district of Keira, but were known to us only by name. That active and successful botanical traveller was able to collect so few specimens that in several cases no duplicates were available for distribution, and the specimens exist only in the rich herbarium of M. Cosson. Among other novelties we here saw for the first time _Trachelium angustifolium_ of Schousboe, utterly unlike any other species of that ornamental genus; _Teucrium rupestre_ and _T. bullatum_, both described by M. Cosson from Balansa’s specimens; and a single specimen of _Elæoselinum exinvolucratum_ of Cosson, a fine umbelliferous plant, apparently very rare even in its native district. A very fine _Brassica_, standing five or six feet high, with a straight upright stem, set with candelabrum-like branches, was the most remarkable new plant found by us which had not already come in the way of M. Balansa. The morning had been cool; the thermometer at 8 A.M. did not rise above 64° F., and the sky was overclouded; but as the day went on the sun blazed out with great power, and this was one of the hottest days we experienced. The heat was, of course, especially felt on bare rocks which became so hot that the hand could not bear them; and the soldier who had gone out by way of protecting us judiciously retired to the shade of a fig-tree at the foot of the hill. After some time, we separated and returned to the camp by different routes. A portion of the slope not far above our camp was altogether covered with broken blocks of moderate size obviously derived from the steeper crags above. This ground abounded in reptiles of various kinds, which were, however, so shy that it was not easy to get a favourable view of them. By sitting perfectly still for some minutes, Ball was partly successful in getting them to approach him. The most remarkable creature much resembled a miniature Iguanodon in form, being about eighteen inches long, with a row of thick conical processes projecting upwards along the back, and gradually diminishing towards the tail from about two inches in height between the shoulders. Numerous lizards were also seen; but no snakes, except a small black viperine species, seen gliding between the stones, actually under one foot, which fortunately did not touch or injure the animal.
