4.Christiana mennegae(Jans.-Jac. & Westra) Kubitzki, Bot. Jahrb. Syst. 116 (4): 541. 1995. Figs 1 C, D, 2 Asterophorum mennegae Jans.-Jac. & Westra, Proc. Kon. Nederl. Akad. Wetensch., C, 86 (3): 377, figs. 1–4. 1983. Type. Suriname: [Sipaliwini], ‘‘ Morro Grande’ ’ camp-forest island, 6 km W of ‘‘ Morro Grande’ ’ dome, Sipaliwini savanna area on the Brazilian frontier, 04 Nov 1968 (lf, fl, fr), F. H. F. Oldenburger, R. Norde, & J. P. Schulz ON 415 (lectotype, designated by Barbosa-Silva et al. 2021, pg. 4, 18): U [U 0006902; digital image!], isolectotypes: K [K 000381142]!, MO [MO- 036999]!, NY [00415374; digital image!], P [P 02143012]!, U [U 0006903; digital image!], VEN [VEN 409940; digital image!]). Type. Based on Asterophorum mennegae Jans.-Jac. & Westra. Description. Trees, 5–17 m tall. Leaves: petioles 1.8–5.5 cm long, leaf blades 12.3–29.5 × 5–9 cm, narrowly elliptic, lanceolate or oblanceolate, concolorous, bases rounded to obtuse, rarely subcordate, margins entire, apices acuminate to cuspidate, stellate-multiangulate and glandular trichomes above and below. Inflorescences short peduncled; flowers attached to peduncle. Capsules syncarpous, 1.2–1.8 cm long, depressed-globose, wings conspicuous. Distribution and habitat (Fig. 2). Found in Suriname, Peru, and Brazil (Amazonas, Mato Grosso, and Pará states) at 500–600 m elevation. This species grows in Amazonian Rainforest and areas of evergreen seasonal forest in Savanna (Barbosa-Silva et al. 2021). Phenology. Flowering specimens collected in January, September, and November and fruiting in January, April, July, September, and November. Conservation status. Least Concern (LC) (Barbosa-Silva et al. 2021). Vernacular name. Brazil: Tartaruguinha. Etymology. The specific epithet honors Dr. Alberta M. W. Mennega, plant taxonomist and wood anatomist (Jansen-Jacobs and Westra 1983). Additional specimens examined. Suriname. Area of Kabalebo Dam project, distr. Nickerie, 4 o- 5 o NB, 57 ° 30 ’ - 58 ° WL, 30–130 m, forest along trail to Wonotobo about ½ km W of road km 109, 24 Sep 1980 (st), J. C. Lindeman et al. 589 [= Woodsample Uw 26517] (NY). Peru.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
