Summary

Pinus × sondereggeri is the only named southern pine hybrid. Its common names include Sonderegger pine and bastard pine. It is a naturally occurring cross between loblolly pine (P. taeda) and longleaf pine (P. palustris). It was originally described by H. H. Chapman (1922), who named it after its discoverer, V. H. Sonderegger, a state forester of Louisiana. More on Wikipedia ›

Cultivation

Grouped as a temperate garden plant, listed under the genus Pinus in the archetype table, and Kew describes it as “tree”, “temperate”.

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 genus Pinus in the archetype table, and Kew describes it as “tree”, “temperate”. 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: 1 in-range record, none placed to within 10 km. 1 of the 1 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.
NativeTexas, Louisiana · 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).
Kew's description“tree” · “temperate” · quoted from WCVP, RBG Kew (CC BY 4.0); not derived here
Evidence usedThe map marker rests on the one georeferenced record inside the native range; none carries a licence permitting republication, so the map shows no points. 7 records 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.

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