Turnera ulmifolia L.

Turnera ulmifolia, the ramgoat dashalong or yellow alder, is a species of plant of family Passifloraceae, native to Mexico and the West Indies. A recent study found that yellow alder potentiated the antibiotic activity against methicillin—resistant Staphylococcus aureus (MRSA).

T. ulmifolia grows erect, with dark toothed leaves and small, yellow-orange flowers, and is often found as a weed growing on roadsides.

This plant is commonly misidentified with the closely related T. diffusa in horticultural commerce, causing it to be often misrepresented as "Damiana."
