At least, that's what I think this is. And apparently they're a rare and endangered species. Also, when looking them up, I found more images of them in their yellow-blooming form than in the cream color, but that may be just because the yellow ones are showier, maybe also easier to spot.
I'm back home, by the way. Expecting a good night's sleep. No x-rays at 2 am, no posting at 3. I'll post the next two sometime later in the morning.
