noteworthy Astragalus observations

December, 2022
Astragalus lentiginosus var. lentiginosus in Nevada County, California:
https://www.inaturalist.org/observations/63800950
this observation is probably the same thing, but lacks pods:
https://www.inaturalist.org/observations/117823148
note that I first thought this was var. salinus but changed my mind based on the prostrate habit and the earlier observation.

October 14, 2022
Astragalus regiomontanus from Tamaulipas - apparently only documented for Nuevo Leon - considered endemic to that state in https://www.jstor.org/stable/24621163
https://www.inaturalist.org/observations/137743741

October 12, 2022
Astragalus robbinsii from Olympic National Park.
https://www.inaturalist.org/observations/118885549

Astragalus cibarius from New Mexico.
https://www.inaturalist.org/observations/137441425
No collections in Seinet. Barneby (1964)maps a collection that is close to this one in southeast San Juan county (and another in west central NM) but does not include NM in his written description.

September 25, 2022
Astragalus convallarius from British Columbia. https://www.inaturalist.org/observations/127922434
No prior documentation north of Helena, Montana. Location appears to be accurate - observed with other plants typical of the location.

September 17, 2022
Astragalus gibbsii from Douglas County, Nevada. No previous county record found.
https://www.inaturalist.org/observations/118714083
https://www.inaturalist.org/observations/103469084
the second observation is more prostrate than usual, but accounted for in Barneby's description
No records of any Astragalus collections in CCH2 or Seinet from Genoa Peak east of Lake Tahoe - appears to be a very poorly collected location. TIL Carson City was in Ormsby County until 1969, now it is an independent municipality, but considered Carson county for census purposes.

September 7, 2022
Astragalus proximus in Cibola County, New Mexico. No previous county record found, and a range extension of ca. 40km to the south. But the Navajo Nation is very poorly represented in herbarium databases, so likely more widespread in the area. https://www.inaturalist.org/observations/126512654

July 26, 2022
Astragalus tioides - perhaps the first record from Guanajuato?
https://www.inaturalist.org/observations/22672866

June, 2022
Astragalus brauntonii in Baja California! Also, a potential new species...
https://www.inaturalist.org/observations/120360892

Astragalus agnicidus in Santa Cruz county, California!
https://www.inaturalist.org/observations/109511560

June, 2021
Astragalus congdonii in Shasta County, California
https://www.inaturalist.org/observations/81469284
range extension of ca. 200 miles from Amador county
is this an introduction or natural occurrence?

April, 2021
Astragalus newberryi var. escalantinus in Arizona (Grand Canyon National Park)
https://www.inaturalist.org/observations/73065502
there is an earlier herbarium specimen from Grand Canyon NP
