Three new species of <i>Rhipidocladum</i> (Poaceae: Bambusoideae: Arthrostylidiinae) from South America
Bibliographic record
Abstract
Three new woody bamboo species from South America, Rhipidocladum arenicolum from Peru, R. cordatum from Ecuador and R. rubrofimbriatum from Venezuela, are here described and illustrated. Based on morphological analysis, R. arenicolum and R. cordatum are placed in sect. Rhipidocladum and R. rubrofimbriatum in sect. Racemiflorum. Rhipidocladum arenicolum and R. cordatum are most similar to R. harmonicum, but R. arenicolum differs in its wider foliage leaf blades and longer spikelets and florets. Rhipidocladum cordatum differs by having cordate culm leaf blades, more branchlets per node and smaller, narrower foliage leaf blades as well as more closely spaced spikelets. Rhipidocladum rubrofimbriatum is most similar to R. sibilans but is awnless, has fewer branchlets per node, and larger, wider foliage leaf blades.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
