The bean, again, first appears in leaf, and then throws out a stalk, which has no articulations[112] upon it. The other leguminous plants have a tough, ligneous stalk, and some of them throw out branches, the chick-pea, the fitch, and the lentil, for instance. In some of the leguminous plants, the pea, for example, the stem creeps along the ground, if care is not taken to support it by sticks: if this precaution is omitted, the quality is deteriorated. The bean and the lupine are the only ones among the leguminous plants that have a single stem: in all the others the stem throws out branches, being of a ligneous nature, very thin, and in all cases hollow. Some of these plants throw out the leaves from the root, others at the top.[113] Wheat, barley, and the vetch, all the plants, in fact, which produce straw, have a single leaf only at the summit: in barley, however, this leaf is rough, while in the others it is smooth. * * * In the bean, again, the chick-pea, and the pea, the leaves are numerous and divided. In corn the leaf is similar to that of the reed, while in the bean it is round, as also in a great proportion of the leguminous plants. In the ervilia[114] and the pea the leaf is long,[115] in the kidney-bean veined, and in sesame[116] and irio the colour of blood. The lupine and the poppy are the only ones among these plants that lose[117] their leaves. The leguminous plants remain a longer time in flower, the fitch and the chick-pea more particularly; but the bean is in blossom the longest of them all, for the flower remains on it forty days; not, indeed, that each stalk retains its blossom for all that length of time, but, as the flower goes off in one, it comes on in another. In the bean, too, the crop is not ripe all at once, as is the case with corn; for the pods make their appearance at different times, at the lowest parts first, the blossom mounting upwards by degrees. When the blossom is off in corn, the stalk gradually thickens, and it ripens within forty days at the most. The same is the case, too, with the bean, but the chick-pea takes a much shorter time to ripen; indeed, it is fit for gathering within forty days from the time that it is sown. Millet, panic, sesame, and all the summer grains are ripe within forty days after blossoming, with considerable variations, of course, in reference to soil and weather. Thus, in Egypt, we find barley cut at the end of six months, and wheat at the end of seven, from the time of sowing. In Hellas, again, barley is cut in the seventh month, and in Peloponnesus in the eighth; the wheat being got in at a still later period.
