Editing Pinus remota (section)

==Taxonomy==
Texas pinyon was previously included in [[Mexican pinyon]], only being discovered as distinct in 1966 when US [[botanist]] [[Elbert L. Little]] noticed that the seed shells of some pinyons in Texas were very thin compared to many others. He treated it as a [[variety (biology)|variety]] of Mexican pinyon, [[Pinus cembroides]] var. ''remota''. Subsequent research found other differences, and it is now usually treated as a distinct [[species]], probably more closely related to the [[Colorado pinyon]] ''P. edulis'', which shares thin seed shells and needles mostly in pairs. Texas pinyon differs from both Mexican and [[Colorado]] pinyons in the very small, recessed umbo on the cone scales (larger and knob-like on other pinyons).
