Summary

Kalanchoe × houghtonii is a hybrid between Kalanchoe daigremontiana and Kalanchoe delagoensis named after Arthur Duvernoix Houghton. It is often confused with Kalanchoe daigremontiana which has strongly cordate to auriculate or even peltate leaves, while the leaves of Kalanchoe × houghtonii are narrower and the leaf base is attenuate, cuneate to weakly cordate or auriculate. In hortuculture, it is often mislabelled as Kalanchoe serrata, which is a different 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 genus Kalanchoe in the archetype table, and Kew describes it as “succulent subshrub”. 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.

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