No place, no publisher, ca. 1860. Folio (34.3 x 21.0 cm). 25 numbered folded leaves, containing dried plants, and three loose, ruled leaves (20.5 x 16.0 cm) with a handwritten index, all in a later portfolio.
An interesting collection of alpine plants, apparently collected by a painter, named Rooyaards, in ca. 1860. A total of 99 specimens, representing different species, are present. The compiler must have been an accomplished botanist, as the captions give the plant names in Latin. The index is of a later date, with Dutch names added in pencil. The plant generally well-preserved. A unique item.
