On our return we found awaiting us a small addition to our Marocco herbarium. With the kind assistance of Mr. Carstensen, we had arranged during our first visit that two natives, who had received a first lesson in the art of drying plants, should start for Agadir early in May, and should bring back whatever plants they could then find in flower. The collection, which we now shared between us, was not of much importance, including, as it did, but a single species not found by us. We doubted, at the time whether the men had, as they solemnly asserted, really reached the neighbourhood of Agadir; but we have now reason to believe that the vegetation of the coast region from Mogador southward to about the twenty-ninth parallel of latitude is very uniform. Since our return from Marocco our friend M. Cosson, with the active assistance of the late M. Beaumier, has succeeded in engaging the services of two native collectors, one of them a very intelligent Jew, the other a Shelluh mountaineer. From the former large collections from the country as far south as the borders of Oued Noun, and as far east as the oasis of Akka, have been sent to Paris; and the latter has contributed a few additions to the flora of the Great Atlas, along with many of the species collected by us. With his accustomed liberality, M. Cosson has sent us duplicates of these fresh contributions to the flora of Marocco. In the afternoon of June 4, we went to pay a farewell visit to the banks of the Oued Kseb, which had been the scene of our first botanical excursion in South Marocco. During the interval of six weeks a great change had passed over the vegetation; most of the annuals were completely dried up and had disappeared; but the excursion was not altogether unproductive, and we were able to add a few plants to our collections.
