Summary

Microsorum thailandicum is a fern in the family Polypodiaceae. It is sometimes called the blue oil fern. Like several other shady understory plant species, its leaves display blue iridescence. Initially unknown, the mechanism was later described as resulting from cellulose microfibrils stacked into helicoidal structures. More on Wikipedia ›

About the genus · Microsorum

Microsorum is a genus of tropical ferns in the family Polypodiaceae, subfamily Microsoroideae, according to the Pteridophyte Phylogeny Group classification of 2016 (PPG I). Like most ferns, they grow from rhizomes, rather than roots. The genus includes some species that are lithophytic rheophytes.

Cultivation

Nothing derived: no habitat climate for this species.

Climate across the habitat

No habitat climate can be derived: No georeferenced record inside the range.

Natural habitat

Native range as published by WCVP.
No openly licensed record to show inside the range.
NativeThailand · regions are the level-3 units of the World Geographical Scheme for Recording Plant Distributions, as Kew's World Checklist records ranges, some under historical names such as Yugoslavia or Czechoslovakia (how).
Evidence usedNo georeferenced record lies inside the stated native range, and all 2 georeferenced records read lie outside it: the range and the records disagree. They are not used, and no map marker or climate is derived from them.

Every source is recorded as having answered, reported nothing, refused, failed, not been asked, or answered twice where one answer is taken (“not taken: two items answered”), and, for a source asked when this page was built, when: the figures are as the source held them that day; a source read from a file (Kew's World Checklist, a GBIF download) says "as of" the file's day instead; a row carried from an earlier build of the page names that build instead. Only “nothing to report” is ever shown as an absence. Records came from 2 datasets via GBIF.org; each carries its own licence.
