Summary

Sabal causiarum, commonly known as the Puerto Rico palmetto or Puerto Rican hat palm, is a species of palm which is native to Hispaniola (in both the Dominican Republic and Haiti), Puerto Rico, and the British Virgin Islands. As its common and scientific names suggest, its leaves are used in the manufacture of "straw" hats.

Cultivation

Nothing derived: no habitat climate for this species.

Climate across the habitat

No habitat climate can be derived: Only 2 distinct land cells of the climate grid hold an in-range record placed to within 10 km; three are needed for an envelope. 85 of the 87 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.

Evidence usedThe map marker rests on all 87 georeferenced records inside the native range; the map shows only the 22 openly licensed ones, which alone would put the marker 443 km away. 48 records outside the WCVP native range not used. No climate across the range is derived for this species. 85 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.
How this section is made
The map marker: the openly licensed record nearest the middle of the densest 1° population of the 87 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 10 datasets via GBIF.org; each carries its own licence.
