= Tristagma fragrans Ravenna (2001: 24) syn. nov. Type:— CHILE. Región Metropolitana. Culta in Santiago, ex Andes La Parva , October 1998, Ravenna 3070 (holotype Herb. Ravenna, not seen; isotypes: BA, BM, not found).

Notes: — Neger (in Dusén 1900), Spegazzini (1902) and Gandoger (1919) published a number of new species and forms from Chile, Tierra del Fuego and the Argentine provinces of Chubut and Santa Cruz, with short and incomplete descriptions from single collections. We regard all these as synonymous with T. nivale . The only material from Neger we could find with relevant data is at UPS. Illin’s material (LP 004259) bears a label with the handwriting of Spegazzini: “ Tristagma eremophilum nov. sp. Speg.”, here considered the holotype. Gandoger, working at Lyon, received material from other botanists, which explains the fact that some of his type specimens, including that of T. chubutense , is at Lyon (LY). There is no material of T. chubutense at Skottsberg’s institution (GB) but there is an isotype at UPSV. The type of T. philippii is also at LY. Up to now, Gandoger’s specimens have not been mentioned in Tristagma literature, as is the case with other species from Tierra del Fuego ( Gandoger 1912). Ravenna (2001) described Tristagma fragrans from a collection made in the Cordillera of Santiago. We studied paratypes cited by Ravenna from the same area, and another from further north (Illapel, Choapa) at the northern limit of the distribution of this species ( Fig. 2B ). All this material is identifiable as T. nivale .

Iconography: — Poeppig, E., Nov. Gen. Sp. Pl., vol. 2: t. 140. 1838; Ravenna, Bol. Soc. Argent. Bot. 11(2- 3):150.1967, fig. 2A ( Fig. 3D )

Conservation status: — Least Concern (LC).
