Camera: 8% battery and no image card.
Ah well, the phone is fine. I noticed, mixed in with the downingia, a somewhat scrubby DYC. It resembled a few things i knew to be weeds ... but not quite. I pulled some up to take home to identify.
HOURS later i have every diagnostic documented, but still no ID.
So, i decided this would be my very first botanical collected specimen. I've pressed this one and the second one i collected. What if it was something special? It's a native, at least, as someone on iNaturalist commented, "tricksy rayless lasthenia!"
I also spent another forever with another plant that looked kinda weedy. I ended up looking at all 200+ plants that were perennial wildflowers known growing in wetland areas of the three south bay counties. I found it: Lythrum hyssopifolia. (Limited invasive species.)
The last two flowers i noted on our outing i've decided can stay at genus level identifications.
(Meeting work is, as usual, outstanding.)
