Ipomoea cardiophylla Gray
Family: Convolvulaceae
Synonyms: Ipomoea aristolochiifolia (Kunth in H.B.K.)
G. Don
Distribution: New Mexico, Dona Ana County; Arizona,
Cochise County; Texas, Trans-Pecos mountains (Correll &
Johnston 1979); Mexico, Chihuahua, Coahuila, Durango, Oaxaca,
Queretaro, and Sonora (Austin 1992)
Habitat: Chihuahuan Desert Scrub
Plants Seen or Cited: Apparently
no records in the New Mexico Natural Heritage Program Database.
One collection at UNM:
Von Loh. No. 687. 23 October 1975. Dona Ana county. 5800 ft. San
Andres Mountains near spring in Ash Canyon.
Comments: The type was collected in the Hueco Mountains,
east of El Paso, Hudspeth County, Texas, in 1849 by Wright.
Discussion: Austin (1992) considers this plant to be globally
rare. He reports poor flowering and fruit set observed over a
very limited time in a small Arizona population in a road right-of-way.
But this evidence is not convincing and considering the huge area
in which it is found, it is hard to agree with his conclusion.
It actually may be rare in United States, but its range is too
large over all for it to receive special consideration in New
Mexico. I suggest placing this plant on L4.
