Asarum acuminatum E. P. Bicknell
Bibliographic record
Abstract
Asarum acuminatum (Ashe) E.P. Bicknell [Aristolochiaceae] Hydra-Flower Wild-Ginger This collection marks the first report for Alabama of this taxon, formerly often only recognized at the varietal level of or under synonymy with A. canadense L. (Ashe 1897; Whittemore et al. 1997; Weakley & Southeastern Flora Team 2023). The next closest observation known for Hydra-Flower Wild-Ginger is from approximately 70 miles (113km) to the north, near Smithville, Tennessee [DeKalb Co., 28 Apr 1992, Kral 80256 (APSC)]. Hydra-Flower Wild-Ginger’s distribution is unclear at present due to only recent widespread recognition, though it appears it is predominantly west of the Blue Ridge Mountains (Estes 2015; Weakley & Southeastern Flora Team 2023). This station in the southern Cumberland Plateau may represent a southerly distribution limit for the species. Asarum acuminatum is distinct from A. canadense by its spreading, long-caudate erect calyx lobes and overall larger calyx tube (see Fig. 23); additionally, its calyx lobes are ascending to antrorse at floral maturity compared to Canadian Wild-Ginger’s retrorse calyx lobes at floral maturity (Estes 2015). Ashe (1897) originally described the taxon as a variety of A. canadense based on these floral characters, as well as its seemingly more membranous, densely pubescent leaves (Kelly 2001). The leaf shape is diagnostic for this taxon later in the growing season; A. acuminatum possesses leaves that are approximately as wide as long, whereas A. canadense has leaves that are wider than their length at maturity (D. Estes, pers. comm.). Additionally, distributions of A. acuminatum and A. canadense are unclear because they were previously considered conspecific with the similar but distinct and southerly Asarum reflexum E.P. Bicknell. The Spaulding et al. (2019) treatment of the genus for Alabama concluded that A. canadense s.s. is currently restricted to Jackson County, which is similar to the range of A. acuminatum in the state. While A. acuminatum and A. canadense both possess larger, spreading calyx lobes that taper to acuminate or revolute tips, respectively (Estes 2015; Weakley & Southeastern Flora Team 2023), A. reflexum, the most common species of deciduous ginger in the state, possesses calyx lobes that are shorter than those of the former two species, gradually taper to an acute and flattened tip, and are sharply reflexed and remain spread at anthesis (Keener et al. 2023). Voucher Specimen: ALABAMA. Jackson Co.: uncommon on NE-facing limestone talus slopes on The Nature Conservancy of Alabama (TNC)/ Paint Rock Forest Research Center property in well-drained soils within seasonal limestone talus wash channels; calyx lobes long tapered and spreading, 18 Apr2021, Noah D.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
