Elliott | Illinois, United States | NC7 |  | | 2017 | COLLECTED | 09/03/2017 | Nachusa Grasslands - locally known as Coyote Point approximately 3.80 miles northwest of Franklin Grove just 0.60 miles west of Lowden Road, T22N R10E NE 1/4 NE 1/4 SW 1/4 Sec. 21, Lee County | 41.87972200, -89.35305600 | 220 | St. Peter's sandstone cliff, specimens noted on ridgetop and on slopes. | Wild material | This accession based on morphological/phenological observations at NCRPIS field plots seems to represent the "southern form" of A. melanocarpa, potentially a new Aronia species. This southern form was originally discovered by Brand et al. 2022 (Ploidy, genetic diversity and speciation of the genus Aronia) and is known for having glabrous stems and leaves and a distinct phyllotaxy than other Aronia species. In addition, plants tend to bloom approximately two weeks later than all other Aronia taxonomic groups and the inflorescences/infructescences are more spreading and extended due to longer peduncles and pedicels within the cyme. Fruit maturity tends to occur 2 to 4 weeks later than tetraploid A. melanocarpa and 4 to 6 weeks later than diploid A. melanocarpa. Phenolic levels are much higher in comparison to other A. melanocarpa accessions (Brand et al., 2017 - Anthocyanins, total phenolics, ORAC and moisture content of wild and cultivated dark-fruited Aronia species.) | 1953928 | Ames 34014 |
