Ecología y Hábitat
Aristolochia watsonii is known from the south of the United States of America (Arizona and New Mexico) and from northwestern Mexico; growing principally in desert vegetation with Larrea, Prosopis, Acacia constricta and Opuntia fulgida, in riparian desert canyons with Artemisia ludoviciana, Brickellia desertorum, Cercidium microphyllum, Carnegiaea gigantea, Fouquieria splendens, alluvial soils, sandy soils, semidesert grassland, tropical deciduous forest, usually in secondary vegetationA

Usos (notas)
Baja California Sur: the roots are used against amoebas, diarrhea, stomachache, diabetes, fever, and malaria; “pasmo” (astonishment that prevents a person from speaking) is treated by mixing A. watsonii with coriander (Coriandrum sativum L.) and “hierba del pasmo” (Haplopappus sonorensis (A. Gray) S.F. Blake); another mix of herbs as tea against stomachache include mint (Mentha spicata L.), basil (Ocimum basilicum L.), the surrounding fibers of coconut husk, and “nicle” (Jacobinia spicigera (Schltdl.) L.H. Bailey), or shoots of “mesquite” (Prosopis sp.), and occasionally the root of “pionillo” (Talinum paniculatum (Jacq.) Gaertn.); the roots are prepared as tea to reduce cholesterol; previously, roots were toasted and grounded and the resulting oil-free powder was used to heal cattle wounds and accelerate the healing of leprosy wounds; cattle wounds are dealt with the root toasted and grounded powder; Sonora: used to expel worms and cure stomachache, to clean sores, and to treat kidney and stomach ailments, the root and stem are used to cure blisters, colic, liver damage, dyspepsia, toothache, “empacho” (name of a condition related with indigestion), and snakebites.A
Discusión taxonómica
This species is easy to recognize by its sagittate to hastate leaves. The limb lanceolate-ovate, cordate at the base, acute to narrowly acute at the apex, with a purplish red to maroon marginal area minutely granular and glabrous, covered by white to dark-purple villose trichomes around, the obovoid throat, yellow with deep purple red dots, covered by villose white trichomes.
Notes—Aristolochia watsonii is one of the species with a wide distribution in Aristolochia subsection Pentandrae and has previously been confused with A. porphyrophylla described by Pfeifer and corrected by the same author in 1976 (see notes below A. lassa). During the fieldwork and comparing herbarium specimens, we realized Aristolochia socorroensis is one of the morphological variations of A. watsonii. The principal differences are in the limb coloration maroon and the rounded limb apex. These differences are not visible in dry material, thus the specimens from A. watsonii and A. socorroensis look the same. They are here sinonymized and the variation is considered to be a consequence of geographic isolation.A
