Penstemon gentianoides
Species of flowering plant
Penstemon gentianoides, the gentian beardtongue or gentian-leaved penstemon, is a species of flowering plant in the plantain family Plantaginaceae. Found on volcanic mountain slopes across Mexico and Central America, especially in Mexican mountain pine forests, it is a somewhat shrubby perennial herb that can grow up to 1.5 meters tall in good conditions. It has dense bundles of leaves and thyrse-shaped flower clusters with 3–6 flowers which are blue-violet. Named for its similarity to gentians, the species was first described in 1817. It was moved from its original genus Chelone to Penstemon in 1825, and was designated the type species of the new section Fasciculus in 1962.
P. gentianoides is pollinated by several species of hummingbirds and bumblebees, but can also self-pollinate. The species is used in folk medicine as an anti-inflammatory and for various other purposes, and some of these properties have been demonstrated in a laboratory setting. A phytochemical study was able to isolate a new iridoid chemical from the plant's extract, which was named pensteminoside.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Penstemon gentianoides”, the useful work is to connect “species of flowering plant” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q15352522. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1817, 1825 and 1962.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
