- Recently a specimen of Astragalus allochrous var. playanus has been photorecorded 5 km west of Mogote (Conejos Co, 2 June 2025—see iNaturalist observation #286527898).This observation would represent the northernmost occurrence of Wooton's milkvetch, a desert Southwest USA plant found mainly in New Mexico and Arizona. The species follows the Rio Grande drainage through New Mexico down to the Big Bend country of Texas. Note that the plant is toxic to livestock. Also note that currently (June 2025), POWO names this taxon Astragalus wootonii var. wootonii. POWO distinguishes the taxon from Astragalus allochrous—A. wootonii having symmetrical pods, A. allochrous asymmetrical pods. Allred et al. (2020) and FNA (2024) note that the pod shape of the two taxa intergrade. They recognize only one genus, A. allochrous, with varieties, among them A. allochrous var. playanus and A. allochrous var. wootonii.
