Another plant from Jeffrey Mine Canyon, this one on the mountainside not far above the bajada, and just off the dirt road leading to the old mine. There were also more N. morefieldii present on the bajada proper, like this one.
I wonder how far north N. morefieldii gets in the White Mountains? This station is roughly 10 miles north of the Coldwater Canyon locality of the voucher Morefield 3433 (RSA), and a bit under 8 miles north of the voucher Howald 4065 (UCR)...which are the two northernmost records cited in Morin & Ayers(2020). These Jeffrey Mine Cyn sightings are also currently the northernmost iNat obs in the White Mnts (though Matt Berger's remarkable eastern NV iNat obs here is actually a bit further north...and way to the east!).
At any rate, I don't see any reason why N. morefieldii shouldn't occur right up to the north end of the White Mountains...and even beyond ;-) Looking forward to the accumulation of more records over time to extend (and fill in) its range.
Another Jeffrey Mine Cyn sighting...along with iNat obs 166368507 and iNat obs 166383672.
