Tristagma gracile (Phil.) Traub (1963: 61) Bas.: Triteleia gracilis Philippi (1873: 550) Brodiaea philippiana Baker (1896: 459) Ipheion gracile (Phil.) Traub (1953: 69) . Type:— CHILE . [ Region Araucania ] Pinales de Nahuelbuta, H. Volcksmann ( holotype SGO 000001125! Fig. 4C .) Note : Philippi (1873) described this species as similar to Triteleia bivalvis , probably based on Poeppig 107 [specimen cited by Poeppig (1833) ], but Volcksmann’s material is clearly distinct from Tristagma bivalve (McRae’s material) by the presence of obtuse tepal apices, the shape of the perigone, the short tepal tube and allopatric distribution (Fig. 1E). Conservation status : Least Concern (LC).
