There are some vines, again, that are remarkable, not for their wine, but for their grapes, such, for instance, as the ambrosia,[1192] one of the “duracinus,”[1193] kind, a grape which requires no potting, but will keep perfectly well if left on the vine, so remarkable is the strength with which it is endowed for withstanding the effects of cold, heat, and stormy weather. The “orthampelos,”[1194] too, is a vine that requires neither tree nor stay, as it is well able to sustain its own weight. This, however, is not the case with the “dactylis,”[1195] the stem of which is no thicker than the finger. The “columbina”[1196] is one of those with the finest clusters, and still more so is the purple “bimammia;” it does not bear in clusters,[1197] but only secondary bunches. There is the tripedanea,[1198] too, a name which it owes to the length of its clusters, and the scirpula,[1199] with its shrivelled berry; the Rhætica,[1200] too, so called in the Maritime Alps, though very different from the grape of that name which is so highly esteemed, and of which we have previously spoken; for in this variety the clusters are small, the grapes lie closely packed, and it produces but a poor wine. It has, however, the thinnest skin of all the grapes, and a single stone,[1201] of very diminutive size, which is known as the “Chian;”[1202] one or two of the grapes on the cluster are remarkably large. There is also the black Aminean, to which the name of Syriaca is given: the Spanish vine, too, the very best of all those of inferior quality. The grapes that are known as escariæ,[1203] are grown on trellises. Of the duracinus[1204] kind, there are those known as the white and the black varieties; the bumastus, too, is similarly distinguished in colour. Among the vines too, that have not as yet been mentioned, there are the Ægian and the Rhodian[1205] kinds, as also the uncialis, so called, it would seem, from its grape being an ounce in weight. There is the picina[1206] too, the blackest[1207] grape known, and the stephanitis,[1208] the clusters of which Nature, in a sportive mood, has arranged in the form of a garland, the leaves being interspersed[1209] among the grapes; there are the grapes, too, known as the “forenses,”[1210] and which quickly come to maturity, recommend themselves to the buyer by their good looks, and are easily carried from place to place.
