Wow, there’s some in there I would love to get myself. Like Androstephium, Jaimehintonia gypsophila, Dandya purpusii. But the latter two are from Mexico, and there doesn’t seem to be as much hobbyist plant growing or exploring down there as in the rest of North America, or even in South America. A lot of the plant explorers of Mexico  (many from Texas) have gotten older or passed away and don’t do it any more. I’ve seen Schoenolirion wrightii growing at the Lady Bird Johnson Wildflower Center in Austin Texas. I once bought some seeds of one of the Androstephium species from, but they never germinated for me.

We  have been able to source material from most genera across the globe,  but have a few sad sampling gaps especially in the southern/southwestern US. Everytime I google for the taxa, I hit the pages of PBS. So, I can´t help wondering whether there might not be some collection holdes who would be prepared to help us complete our sampling and elucidate the evolution of this fascinating group of plants. We are particulaly looking for (ideally vouchered) leaf samples of:///Pseudogaltonia/, Androstephium, Jaimehintonia gypsophila, Dandya purpusii, Triteleiopsis palmeri, Xochiquetzallia, Hooveria, Schoenolirion, Eremocrinum, Diuranthera, Trihesperus, Diamena stenantha, Diora cajamarcaensis, Hemiphylacus. Any chance you can help us contact somebody who might help with one or the other species?
