Identifying an Obscure Plant from Coastal Oaxaca, Mexico

A researcher needed ID for a 1-meter yellow-flowered plant in pasture/wetland in coastal Oaxaca.

Expert Limitation

Obscure regional plants **require physical specimens** (flower, leaf, seed) and **local botanical keys**—none of which the expert possessed.

Recommended Path

• Consult **Mexican herbaria** (e.g., UNAM, INECOL).
• Contact **ethnobotanists** working in Oaxaca.
• Use **iNaturalist** or **Pl@ntNet** with clear geotagged photos.
• Seek **local guides** or university botanists in the region.

Remote ID for hyper-local flora is rarely reliable.
