The Patten collection consists of two small field notebooks and three loose-leaf notebooks with holes for brads (two were tied with blue silk ribbon which was removed and retained). The field notebooks are formatted in columns with the following headings: number, date, place, formation (e.g. meadow, woods, on wall), soil etc., altitude, height, (Latin) name, and remarks. The loose-leaf notebooks contain identifications and descriptions for plants collected in Greece, arranged by family.
