Dyschoriste decumbens (A. Gray) Kuntze

UNITED STATES. New Mexico. Hidalgo Co.: Gray Ranch in Animas Mountains , T31 S, R18 W , 6000 ft, 15 September 1990, R . Dewitt Ivey 101 ( UNM), 192 ( UNM), 262 ( UNM); along lower Indian Creek , N end of Animas Mountains , 5400 ft, 23 Jul 1975, W . Wagner 1292 ( UNM) .

Kobuski (1928) recorded and mapped the occurrence of Dyschoriste decumbens in New Mexico based on collections of Charles Wright (1462, 1463; both at MO) from the “Valley of the Rio Grande” made in 1851. According to Johnston (1940) and Shaw (1987), at least Wright 1463 was collected in western Texas (Pecos Co.: Escondido Springs to Comanche Springs [= Ft. Stockton]), and is probably referable to D. cinerascens (Henr. & Hilsenb.) T.F. Daniel ( Daniel 2013). The locality of Wright 1462 remains uncertain, but if collected from the Rio Grande Valley of New Mexico, it would also likely pertain to D. cinerascens . Martin and Hutchins (1981: Map 1052) noted the presence of Dyschoriste decumbens in Eddy County, New Mexico, and Daniel (1984) cited collections from Chaves, Eddy, and Lincoln counties in southeastern and south-central New Mexico. All collections of Dyschoriste from those counties were subsequently treated by Daniel (2013) as D. cinerascens . Daniel (2013) recently noted that D. decumbens is widespread in southeastern Arizona and northwestern Mexico, and uncommon in western Texas; its presence in southwestern New Mexico was shown on a map. The collections noted above from Hidalgo County document its occurrence in that county and state.
