Solanderia
genus of cnidarians
Solanderia is the sole genus of hydrozoans in the monotypic family Solanderiidae. They are commonly known as tree hydroids or sea fan hydroids.
Description
Solanderia hydroids forms large colonies. They are one of about 1000 species of athecate hydroids, which do not construct a skeletal covering for their polyps (as opposed to the thecate hydroids in the order Leptothecata. The chitinous skeleton is internal, branches, and may form anastomoses. The skeleton is formed by coalescence and modification of adjacent hydrocauline tubes. The coenosarc covers the entire colony and penetrates skeletal interstices. The hydranths cover the whole colony surface and are uniform in structure, cylindrical, with a single whorl of capitate tentacles around the mouth. Numerous similar tentacles are scattered over the body. Solanderia is known from its polyp or hydroid stage, and produces gonophores which release sperm and eggs for reproduction.
Begin with the source’s own compact description: “Solanderia” is genus of cnidarians. The dossier treats that line as a proposition to test through Solanderia, genus and cnidarians, not as a finished interpretation.
Why this record matters
The phrase “genus of cnidarians” 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 May 18, 2026. The linked authority identifier is Q4005785. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1000.
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.
