Turnera ulmifolia, the ramgoat dashalong{{PLANTS|id=TUUL|taxon=Turnera ulmifolia|access-date=12 December 2015}} 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).{{cite journal|last1=Coutinho|first1=Henrique DM|last2=Costa|first2=José GM|last3=Lima|first3=Edeltrudes O|last4=Falcão-Silva|first4=Vivyanne S|last5=Siqueira Júnior|first5=José P|title=Herbal therapy associated with antibiotic therapy: potentiation of the antibiotic activity against methicillin – resistant Staphylococcus aureus by Turnera ulmifolia L|journal=BMC Complementary and Alternative Medicine|volume=9|issue=1|year=2009|issn=1472-6882|doi=10.1186/1472-6882-9-13|pmid= 19426487|url= |pmc=2685411|pages=13 |doi-access=free }} {{open access}}
Description
File:Ramgoat dashalong or yellow alder.jpg
Turnera ulmifolia grows erect, with dark toothed leaves and small, yellow-orange flowers, and is often found as a weed growing on roadsides. These yellow flowers bloom around 6:00 a.m. and wilt around 11:30 a.m. Life span for flower is around six hours. These plants can survive on minimum water and grow on walls, cement blocks, and rocks. Tawny Coster (Acraea terpsicore) butterfly larvae feed on these plants. This plant is commonly misidentified with the closely related T. diffusa in horticultural commerce, causing it to be often misrepresented as "Damiana."{{cite journal|last1=Joshi|first1=V.C.|last2=Rao|first2=A.S.|last3=Wang|first3=Y.H.|last4=Avula|first4=B.|last5=Khan|first5=I.A.|title=Taxonomic Clarification on Turnera diffusa Ward and its Demarcation from "False Damiana" using Fluorescence, Scanning Electron Microscopy, HPTLC and UPLC|journal=Planta Medica|date=March 2009|volume=75|issue=4|doi=10.1055/s-2009-1216454|doi-access=free}}{{cite web|title=Damiana - Turnera diffusa, Turnera ulmifolia seed pictures|url=https://www.shroomery.org/forums/showflat.php/Number/14429711|website=shroomery.org|access-date=7 September 2016}}{{cite web|title=Turnera diffusa var diffusa or var aphrodisiaca or what?|url=http://garden.org/thread/view/33308/Turnera-diffusa-var-diffusa-or-var-aphrodisiaca-or-what/?offset=0|website=National Gardening Association|access-date=7 September 2016}}
