22. Osmorhiza berteroi Candolle (1830: 232) .

Lectotype (designated here):— CHILE. In sylvis umbrosis prope Tagua Tagua, C. L. G. Bertero 446 (G00664656!; isolectotypes GH00077315!, P00758097!, P00758099!, P00758100!).

Notes:— In the protologue of Osmorhiza berteroi, Candolle (1830) cited a collection from Tagua-Tagua , Chile (“in sylvis umbrosis prope Tagua Tagua”) by Bertero , but did not indicate a collection number. We have found five herbarium sheets that coincide with the protologue. The labels from P00758099 and P00758100 do not perfectly match the indication of the original locality as “in sylvis umbrosis prope” is missing, however, the other three specimens (G00664656, GH00077315 , P00758097) do have the complete locality information. From these, P00758097 is mounted on the same sheet with Bertero 1160 from a different locality (P00758098), which may cause confusion ; specimens G00664656 and GH00077315 are both complete and well preserved, but the one at G was part of De Candolle´s herbarium. Therefore, we designate G00664656 as the lectotype. It is worth noting that there are other specimens collected by Bertero with the same number as the lectotype designated herein (446), but these are not part of the original material of O. berteroi because they differ in the locality data (G00367087, M0172503).
