I have various plants labeled Hymenocallis riparia and H. sonorensis. They all came to me from other hobbyists, with no wild provenance, and they all look alike to me. How might one distinguish between the two species, lacking wild collection data? It would be nice to have a pocket sized DNA sequencer in my kitchen! I would still need reference plants of known provenance, of course.
