Alsophila glaberrima
species of plant

Alsophila glaberrima, synonym Cyathea glaberrima, is a species of tree fern endemic to the D'Entrecasteaux Islands, specifically Fergusson Island and Goodenough Island, where it grows in mossy forest at an altitude of 900–1,400 m (3,000–4,600 ft). The trunk is erect and usually about 2 m (6 ft 7 in) tall. Fronds may be bi- or tripinnate, are 1–2 m (3 ft 3 in – 6 ft 7 in) in length, and form a dense crown. The stipe is finely warty and bears numerous glossy scales with fragile edges. Sori are produced close to the fertile pinnule midvein. They are protected by small, dark brown indusia that are scale-like in appearance.
Begin with the source’s own compact description: “Alsophila glaberrima” is species of plant. The dossier treats that line as a proposition to test through Alsophila, glaberrima and species, not as a finished interpretation.
Why this record matters
The phrase “species of plant” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Dec 27, 2025. The linked authority identifier is Q17185033. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
