Abstract

fetched live from OpenAlex

The poorly known Western Australian species of the red algal genera Callithamnion Lyngb. and Corynospora J.Agardh (Ceramiales) described by William Henry Harvey in his seminal 1855 paper are reassessed based on morphological and molecular analyses of original and recent collections. Several generic reassignments are proposed, including Desikacharyella australis (Harv.) Huisman, Verbr. & G.W.Saunders (for Corynospora australis Harv.), Guiryella gracilis (Harv.) Huisman, Verbr. & G.W.Saunders (for Corynospora gracilis Harv.), Anotrichium flabelligerum (Harv.) Huisman, Verbr. & G.W.Saunders (for Callithamnion flabelligerum Harv.), Pleonosporium perpusillum (P.C.Silva) Huisman, Verbr. & G.W.Saunders and Pleonosporium crispulum (Harv.) Huisman, Verbr. & G.W.Saunders (for Callithamnion perpusillum P.C.Silva and Callithamnion crispulum Harv.), Aglaothamnion scopula (Harv.) Huisman, Verbr. & G.W.Saunders (for Callithamnion scopula Harv.) and the elevation of Anotrichium thyrsigerum (Harv.) Huisman, Verbr. & G.W.Saunders (for Callithamnion thyrsigerum Harv., previously treated as a variety or synonym of Anotrichium tenue (C.Agardh) Nägeli) to species level. In addition, Callithamnion cliftonii Huisman, Verbr. & G.W.Saunders is proposed as a replacement name for the illegitimate Callithamnion multifidum Harv. and this, and Callithamnion debile Harv., are retained in the genus. Two new species, Ptilothamnion harveyanum Huisman, Verbr. & G.W.Saunders and Seirospora decipiens Huisman, Verbr. & G.W.Saunders, are described from recent collections.

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.

Not 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.
