Le Orchidee Spontanee dell Provincia Granda. 2020. illus. 507 p. gr8vo. - In Italian, with Latin nomenclature.

The spontaneous orchids of the Granda Province" by Renato Lombardo and Fernando Morelli tells one of the natural treasures that is little by little disappearing through 508 pages and 870 color photographs: 74 species of spontaneous orchids, divided into 24 genera; to these are added the numerous subspecies, hybrids, chromatic variants and morphological anomalies (lusus).

The Alta Langa and the Alpine valleys, places united by progressive abandonment, are the kingdom of orchids, an example of plant biodiversity of international importance. Small, sometimes almost invisible, fragile, precarious, exposed to every type of insult, spontaneous orchids grow on arid soil of no value or in the impassable shadows of the undergrowth.
