Scientific name:
Gymnospermium scipetarum subsp. eddae Rosati, Farris, Fascetti & Selvi
Common name:
Edda's Tuberous Herb
Family:
Berberidaceae
Biological form:
Geofita tuberosa

Characteristics

Habit: A small, glabrous, perennial herbaceous plant. Being a geophyte, it spends the adverse season as an underground tuber, producing an erect, delicate flower spike in early spring. Leaves: They generally appear with or immediately after the flowers; they are compound, deeply divided into lobed segments, and are glaucous-green in color. They have a tender texture, typical of shade-loving plants that grow in the undergrowth. Flowers: Grouped in a terminal racemose cyme bearing small, hermaphroditic flowers. The perianth is composed of bright yellow petals. Compared to the nominate Balkan subspecies (subsp. scipetarum), this Italian subspecies exhibits morphological and microscopic diagnostic differences: a lower ratio between the length of the stamens and that of the petals (shorter stamens) and a lower ratio between the length of the style and that of the carpel. Fruit: A membranous capsule that cracks early at maturity. This characteristic exposes the immature seeds prematurely, leaving them visible and "naked" on the plant. Flowering: March - April

Distribution and habitat

Chorological type: Endemic to Italy. Distribution in Italy: Extremely rare and exclusive species (point-like endemicity) of the southern Apennines. It is located in a very restricted forest area between the Maddalena Mountains in the Padula area (Salerno). Habitat: Grows exclusively in the undergrowth of cool, shady forest environments (beech forests and mixed mesophilous woodlands), on humus-rich soils, in an altitudinal range of approximately 1000 meters above sea level.

Etymology

Genus (Gymnospermium): Derived from the Greek words γυμνός (gymnós, naked) and σπέρμα (spérma, seed). The name explicitly refers to the peculiarity of the fruit, whose membranous pericarp ruptures very early in development, leaving the immature seeds exposed and visible on the outside.

Species (scipetarum): The epithet derives from the Albanian term Shqipëtar (Albanian, "Son of the Eagles"). It indicates the geographic origin of the species, originally described from populations found in Albania.

Subspecies (eddae): The epithet is dedicated to Edda Lattanzi, an eminent and historic Italian botanist and specialist in the Rosa genus. The plant was discovered and described in her honor during preparations for a field trip by the Italian Botanical Society, which she strongly promoted.

Curiosities

It is considered a threatened species due to its small populations and its extremely specific microhabitat.
