Flower ID: IMG_0916.JPG-05-17-2024 Flower name (scientific): Borodinia dentata (Rafinesque) P. J. Alexander & Windham PY: 2013. Pronunciation guide: (phonetic spelling) bor-o-DIN-ee-uh den-TAY-ta Flower name (common): Toothed Rock Cress Family name (common): Mustard Family name (scientific): Brassicaceae Scientific name origin: Genus: Possibly named to honor the Russian botanist Ivan Parfenievich Borodin (1847 - 1930), founding president of the Russian Botanical Society of the Russian Academy of Sciences (1916 - 1930). Specific epithet: Latin for having teeth, refers to the dentate margins of the basal leaves. Common name origin: From the appearance of the margins of the basal leaves, and from a common growing habitat. Cress is a common name for a number of plants having edible leaves that have a bitter flavor. The term rockcress is used for several species of small plants that are cultivated as an ornamental for rock gardens (OED). Flower description: Size: 0.1 to 0.16 inches (2.5 to 4 mm) Petal count: 4 Color: white Other: flower arrangement, Raceme Plant description: Size: 8 to 20 inches (20 to 51 cm) Stem hairy: pubescent Other: Leaf description: attachment is basal and alternate, type is simple Size: Stem leaves up to 6 cm long, basal leaves up to 15 cm long and up to 4.5 cm wide. Color: medium green Hairy: Upper stem leaf surfaces sparsely pubescent. Basal leaf surfaces sparsely pubescent. Other: Shape: leaf, basal and cauline leaves oblanceolate or obovate (IL), cauline leaves Stem leaves narrowly oblanceolate to nearly linear (MB) Origin (native, introduced, invasive): Native Status (common, uncommon, threatened, rare): Uncommon Bloom time (typical): April to May Cycle (annual, biennial, perennial): Biennial Habitat: Floodplains, mesic forests, woods, streambanks, rocky ledges, bluffs, shade to sun, moist. Fruit: Siliques are flattened, up to 4 cm in length, and spreading to ascending. Seed: Approximaetly 1 mm in length, and about 0.5 mm wide. Importance to wildlife: Similar species (if any): Borodinia canadensis (Sickle-pod) (formerly called Boechera canadensis) and Boechera grahamii (Spreading-pod Rock Cress) have some similar features to Borodinia dentata. Borodinia canadensis has basal leaf blades obovate to oblanceolate and 10 to 30 mm wide, Boechera grahamii has basal leaf blades oblanceolate, and 1.5 to 10 (up to 20) mm wide, whereas Borodinia dentata has basal leaf blades obovate to oblanceolate, and (6-) 10 up to 45 mm wide. The Boechera and Borodinia genera are a fairly complex group to sort out into different species, which requires examination of micromorphological characteristics (Al-Shehbaz, 2010). Borodinia dentata has petals barely longer than the sepals, Boechera grahamii has sepals about half the length of the petals, and Borodinia canadensis has spreading petals slightly longer than the sepals.
