10. Polygala salasiana Gay (1845: 237)

Lectotype (designated here): — CHILE. [VI Región]. Provincia de Colchagua. Talcaregue (Cajón del Azufre) C. Gay 200 (P 00733548!; isolectotypes G [Herb. De Candolle], G [Herb.Delessert], P 00733549!, P 00733550!, GH 00027004!, SGO 000002986!, K 000590883!)

Protologue citation:—“Esta especie se cria en las grietas de los peñascos de las cordilleras de Talcaregue, y especialmente en el Cajon del Azufre en una altura de 8240 piés”.

Notes: — Gay wrote in his travel notes ( Barros Arana 1876: 49) that on March 20th 1831, before reaching the foot of the Tinguiririca Volcano , he collected two species of Polygala . One of these collections is the P 00733548 specimen, bearing a label that reads: “ Provincia Colchagua, Polygala andicola . In fissuris andinis. Talcaregue (Cajón del Azufre). T. basaltique. Rarissima. ( Chili.)”. Its collection number is 200 and it consists of two sheets. We designated the sheet P 00733548 as a lectotype as it is the most complete specimen, has a label matching the diagnosis, and agrees with the protologue description. Three duplicates of this collection were also examined: a specimen at GH, without a collection number, stamped “Donné par le Museum d’Histoire Naturelle de Paris”, and annotated “cordillera de Talcaregue Cajon del Azufre 8240 feet ” ; K 000590883 specimen, donated by the National Museum of Natural History , Paris, on a sheet that includes some other material of P. salasiana ; a specimen at SGO bearing a label that reads: “Prov Colchagua. Polygala . In fissuris … andinum. Talcaregue Febr 1831” and written in the same hand as that of 200, later crossed out and replaced by the number 1064 written in a different hand.

Distribution:— This is the most austral species of Polygala , found growing in the Andes of Chile and Argentina, from Mendoza to Tierra del Fuego.
