Such is the nature of the tree that is so called in Africa; the same name being also given to a certain[944] herb, and to a stalk[945] that grows in Egypt belonging to the marsh plants. This last plant springs up when the waters of the Nile have retired after its overflow: its stalk is similar to that of the bean, and its leaves are numerous and grow in thick clusters, but are shorter and more slender than those of the bean. The fruit grows on the head of the plant, and is similar in appearance to a poppy in its indentations[946] and all its other characteristics; within there are small grains, similar to those of millet.[947] The inhabitants lay these heads in large heaps, and there let them rot, after which they separate the grain from the residue by washing, and then dry it; when this is done they pound it, and then use it as flour for making a kind of bread. What is stated in addition to these particulars, is a very singular[948] fact; it is said that when the sun sets, these poppy-heads shut and cover themselves in the leaves, and at sun-rise they open again; an alternation which continues until the fruit is perfectly ripe, and the flower, which is white, falls off. (18.) Even more than this, of the lotus of the Euphrates,[949] it is said that the head and flower of the plant, at nightfall, sink into the water, and there remain till midnight, so deep in the water, that on thrusting in one’s arm, the head cannot be reached: after midnight it commences to return upwards, and gradually becomes more and more erect till sunrise, when it emerges entirely from the water and opens its flower; after which it still continues to rise, until at last it is to be seen raised quite aloft, high above the level of the water. This lotus has a root about the size of a quince, enveloped in a black skin, similar to that with which the chesnut is covered. The substance that lies within this skin is white, and forms very pleasant food, but is better cooked, either in water or upon hot ashes, then in a raw state. Swine fatten upon nothing better than the peelings of this root. CHAP. 33. (19.)—THE TREES OF CYRENAICA. THE PALIURUS. The region of Cyrenaica places before the lotus its paliurus,[950] which is more like a shrub in character, and bears a fruit of a redder colour. This fruit contains a nut, the kernel of which is eaten by itself, and is of a very agreeable flavour. The taste of it is improved by wine, and, in fact, the juices are thought to be an improvement to wine. The interior of Africa, as far as the Garamantes and the deserts, is covered with palms, remarkable for their extraordinary size and the lusciousness of their fruit. The most celebrated are those in the vicinity of the Temple of Jupiter Hammon. CHAP. 34.—NINE VARIETIES OF THE PUNIC APPLE. BALAUSTIUM.
