Scalesia affinis
species of plant endemic to the Galapagos Islands
Scalesia affinis is a species of flowering plant in the family Asteraceae. It is endemic to the Galápagos Islands, Ecuador.
It is one of the most widely distributed Scalesia species and occurs on four major islands: Fernandina Island, Isabela Island (main distribution area), Santa Cruz Island and Floreana Island.
Populations from Santa Cruz and Floreana display some morphological and genetic divergence from populations of Fernandina Island and Isabela Island.

This brief starts where responsible research should: with the source description of “Scalesia affinis” as species of plant endemic to the Galapagos Islands. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant endemic to the Galapagos Islands. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Oct 6, 2025. The linked authority identifier is Q5230526. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1974 and 2004.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
