Sideroxylon marginatum
species of plant
Sideroxylon marginatum is a species of flowering plant in the family Sapotaceae. It is endemic to the Cape Verde Islands, where it is a mesophytic species whose habitat is now limited to steep escarpments and inaccessible places. It is threatened by continued habitat loss.
Distribution
There are records of the species on seven islands in the Cape Verde archipelago – Santo Antão, São Vicente, São Nicolau, Sal, Boavista, Santiago, Fogo, and Brava, between 500 and 1,200 meters elevation. Its range has decreased from human activity, and it is currently extinct in the wild on São Vicente, Sal and Boavista.
Species delineation
It was formerly considered a subspecies (marginata) of Sideroxylon mirmulano, which is native to Madeira. Plants of S. mirmulano from the Canary Islands are now considered Sideroxylon canariense.
This brief starts where responsible research should: with the source description of “Sideroxylon marginatum” as species of plant. 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. 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 5, 2025. The linked authority identifier is Q15346827. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
