Petals are united, forming an inferior ovary. Calyx is 3-5 mm long the lobes are lanceolate to acuminate, not conspicuously spotted. Stamens inserted near the mid tube; stigma slightly exceeding the anthers. Parts are in 5’s (5, 6, 7)

Fruit: 5-8 mm long, seeds 4-7/locule(5)

Similar species: This species is similar to Ipomopsis aggregata but can be separated by length of corolla tubes. Ipomopsis aggregata has a corolla of 18-25 mm in length, with the anthers and style longer than the tube. Ipomopsis arizonica has a corolla of 10-15 mm, with it’s anthers and stamens included in the tube (5).

Phenology: Flowers from May-October (5)

Distribution: Arizona, California, Nevada, Utah. From 5000-8000ft(1500-3100m.) Grows in open areas tending to be sandy in Pinyon-Juniper and Coniferous forests. In Arizona found in Coconino and Mohave counties (5, 8)
