About the genus · Crinum

Crinum is a genus of about 180 species of perennial plants that have large showy flowers on leafless stems, and develop from bulbs. They are found in seasonally moist areas, including marshes, swamps, depressions and along the sides of streams and lakes in tropical and subtropical areas worldwide.

Cultivation

Grouped as a bulb, tuber or caudex, listed under the family Amaryllidaceae in the archetype table, and Kew describes it as “bulbous geophyte or helophyte”.

Nothing derived: no habitat climate for this species.
How this section is made

Each card states this species' habitat figures with their sources, and what two fixed rules read from them; nothing here says what the plant does, wants or tolerates. The rules · the terms.

Group. Listed under the family Amaryllidaceae in the archetype table, and Kew describes it as “bulbous geophyte or helophyte”. A group is taken only where Kew's description of the species agrees with the table's listing. The table gives no figure and no prose; the cold floor is the habitat's alone.

Climate across the habitat

No habitat climate can be derived: Only 1 distinct land cell of the climate grid holds an in-range record placed to within 10 km; three are needed for an envelope. 36 of the 37 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.
NativeThe Gambia, Ghana, Guinea-Bissau, Guinea, Ivory Coast, Nigeria, Senegal, Sierra Leone, Cameroon, Congo, Equatorial Guinea, Gabon, Gulf of Guinea Is., Zaïre, Sudan, Angola · 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).
Map marker4.406, 9.13 · in the densest population, 17 records (46% of those in range)
Kew's description“bulbous geophyte or helophyte” · “seasonally dry tropical” · quoted from WCVP, RBG Kew (CC BY 4.0); not derived here
Evidence usedThe map marker rests on all 37 georeferenced records inside the native range, all openly licensed and shown on the map. 1 record outside the WCVP native range not used. No climate across the range is derived for this species. 36 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 37 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.
