Erect perennial to 1.2m high. Flower heads were smaller than other T. composita I've seen, and leaves were glabrous, though this may be due to the exposed location? Petioles were quite long, possibly ruling out T. incisa?

Pozoa coriacea Lag. Gen. Sp. Pl.: 13 (1816). [Accepted name (Apiaceae) native range is Argentina Northwest, Argentina South, Chile Central : http://powo.science.kew.org]. Leaves 15L x 17W mm. Umbel diam 23 mm.

Flowering and fruiting at about 14 months after high intensity fire in a montane bog at 1090m elevation. My other recent coastal record of this species fruiting (https://www.inaturalist.org/observations/70544885) was also after fire. Not sure if this is coincidence or not. I've been identifying this species from its distinctive leaf shape in local montane swamps for a few years, but never caught it in any sort of reproductive state before. The winged fruits are nice and obvious on this plant.
