Plinii Secundi quae fertur una cum Gargilli Martialis medicina: Nunc primum edita a Valentino Rose.

Fragments of Martialis's work (probably called De hortis), which treated of the cultivation of trees and vegetables, and also of their medicinal properties, survived, chiefly in the body of and as an appendix to the Medicina Plinii (an anonymous 4th century handbook of medical recipes based upon Pliny the Elder, Naturalis Historiae, xx–xxxii). Extant sections treat of apples, peaches, quinces, citrons, almonds, chestnuts, parsnips, and various other edibles, with an emphasis on the medical effects they have on the body (quoting Dioscorides sometimes).
