Dorignum quod alii cacabum dicunt. Dya.: Folia habet in colore similia olive sed paulo longiora et aspera, florem album, semen velut orobi, varium in folliculis suis et cetera.
Dorignum: Some people call it cacabum. Dioscorides: "It has leaves similar in color to the leaves of the olive but a little longer and rough, a white flower, a seed like the seed of the bitter vetch, of various forms in its pods, et cetera".
This plant is bindweed (Convolvulus oleifolius).
This is a quotation from the Alphabetical Latin Dioscorides (ed. Colle, 1478, f. 41v : litt. D, cap. 9). It is different from translation-C of Dioscorides but must come from a distinct translation (probably translation-B).
Both are translated from the original Greek text: δορύκνιον /dorýknion/ 4, 74, ed. Wellmann (1906-14: II.233).
