Rank Reasons
Ipomopsis macombii ranges from southwestern New Mexico (4000-6500 feet) and southeastern Arizona (4000-8000 feet) into Mexico. In the U.S.A., it occurs on rocky slopes and in openings in pine forest.
Range Extent Comments
The main range of Ipomopsis macombii is about 150,000 square km (60,000 square miles) in mountainous areas of the Sky Islands and Mogollon Mountains of southeastern Arizona, and southwestern New Mexico, and the northern Sierra Madre of eastern Sonora, and western Chihuahua states in Mexico. The full range four times larger, including disjunct populations in northern New Mexico (USA), and to the southeast near Monterrey in Nuevo Leon and Coahuila states, Mexico (SEINet 2018, Villaseñor 2016).
Occurrences Comments
There are 240 collections of Ipomopsis macombii (SEINet 2018), there are also 30 citizen science observations (iNaturalist 2018). Not all of these are from unique locations, however.
Threat Impact Comments
Overgrazing and severe drought (especially associated with climate change) are threats.
Ecology & Habitat

Description

Ipomopsis macombii is an herbaceous forb which is glandular and pilose and has deeply divided, almost needle-like leaves. The flowers are purplish with the corolla tube 15 - 25 mm (0.6 - 1.0 inch) long, curved slightly downward, the anthers included to only slightly exserted (Wilken and Porter 2005).

Diagnostic Characteristics

The inflorescence of Ipomopsis macombii is usually one-sided, with subsessile flowers crowded near tips of short, lateral branches. The flowers are short-pedicelled to subsessile, in lateral, pedunculate clusters. Corollas are purplish, the tube 15-25 mm long, bent slightly downward; the calyx lobes short-aristate (Wilken and Porter 2005).

Habitat

Ipomopsis macombii occurs in desert mountain areas, in oak and juniper communities, in openings in pine, dry meadows, coniferous forests, and in brushy canyon bottoms in sandy to gravelly soils at 1430-2690 m (4700-8800 ft) elevation (Allred and Ivey 2012, Wilken and Porter 2005).
