Summary

Ranalisma rostrata (wrong: rostratum) is a critically endangered marsh plant species, one of only two species in the Ranalisma genus of the family Alismataceae. It was first described and published by Stapf 1900. It is included in the list of China national level I key protection plants, and after the introduction of breeding programs in China the population has been increasing. Studies have shown that both volatile compounds and water extracts derived from Isodon globosa and Pogostemon praetermissum exhibit significant inhibitory effects on the seed germination of R. rostrata.

Cultivation

Nothing derived: no habitat climate for this species.

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. 1 of the 2 in-range records is 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 it counts for the map and its marker.

Natural habitat

Native range as published by WCVP.

No openly licensed record to show inside the range.

Kew's description“helophyte” · “wet tropical” · quoted from WCVP, RBG Kew (CC BY 4.0); not derived here

Evidence usedThe map marker rests on all 2 georeferenced records inside the native range; none carries a licence permitting republication, so the map shows no points. 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. 1 in-range record is placed to worse than 10 km, or with no stated accuracy (admitted only as a person's observation to three decimals), and stays on the map but off the climate.

Photographs

Not checked. iNaturalist was skipped (not asked) when this page was built; GBIF's observation records with coordinates hold none. Not a statement that none exist.

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.
