9. Polygala sabuletorum Skottsberg (1916: 255)

Lectotype (designated here):— ARGENTINA. Santa Cruz. Lago Buenos Aires. C. Skottsberg 644 (S-R-10257!)

Protologue citation:—“Andines Patagonien: sandige Steppe im Fenix-Tal, Treibsandfelder zw. Rio Fenix und Lago Buenos Aires (Bl. 2, 10.-11. 12. 08); sandige Flussbarranca des Rio de los Antiguos, s. vom Lago Buenos Aires (Bl. 2, 13. 12. 08)”.

Notes: —Carl Skottsberg collected this specimen during the Swedish Magellanic expedition of 1907-09 ( Skottsberg, 1911), a scientific expedition whose main purpose was to study the geography, geology, and flora of Patagonia . Describing the species, Skottsberg (1916: 255) cited two syntypes, of which the S-R-10257 specimen is designated here as the lectotype as it fully matches the protologue description and was collected by Skottsberg himself on 11 December 1908 in “ Patagonia andina , sanddyner vid Lago Buenos Aires ”. The syntype from Río de los Antiguos has not been located.

Distribution:— Found growing in canyons of the Chubut and Santa Cruz provinces of Argentina.
