Summary

Doodia caudata is a species of dimorphic, evergreen fern in the family Blechnaceae, native to Australia and New Zealand. Upright clusters of fertile fronds reach 25 cm (10 in) in length. It has been introduced to the Azores, Madeira and Sri Lanka.

Quoted from Wikipedia, "Doodia caudata", CC BY-SA 4.0; its title is one of this species' older names (GBIF Backbone), which is the proof that the article is this species'.

Cultivation

Nothing derived: no habitat climate for this species.

Climate across the habitat

No habitat climate can be derived: 10 in-range records, none placed to within 10 km. 10 of the 10 in-range records are placed to worse than 10 km, or to no stated accuracy and fewer than three decimals or by something other than a person's observation, and cannot place a climate cell, though they count for the map and its marker.

Natural habitat

Native range as published by WCVP; the marker is where the records are densest and decides nothing.
Openly licensed records inside the range, framed on where they fall.

This species has no GBIF key of its own. Its records are GBIF's under the key of the name Kew's World Checklist holds as this plant: 4078732 (Blechnum spinulosum Poir., 12 records). No name was matched to GBIF; the keys are read from Kew's synonymy. How.

Kew's description“subtropical” · quoted from WCVP, RBG Kew (CC BY 4.0); not derived here
Evidence usedThe map marker rests on all 10 georeferenced records inside the native range, all openly licensed and shown on the map. 1 record outside the WCVP native range not used. Under a dozen records behind the map. No climate across the range is derived for this species. 10 in-range records are placed to worse than 10 km, or with no stated accuracy (admitted only as a person's observation to three decimals), and stay on the map but off the climate.
Other GBIF keysRecords also from GBIF's key 4078732 (Blechnum spinulosum Poir.): Kew's file holds it as Blechnum spinulosum Poir. (accepted); 12 records, from GBIF's download.
How this section is made
The map marker: the openly licensed record nearest the middle of the densest 1° population of the 10 in-range records; it decides nothing. Records outside the native range, living specimens and records marked introduced are not used; which records count.

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 3 datasets via GBIF.org; each carries its own licence.
