Pogogyne tenuiflora
species of plant
Pogogyne tenuiflora is an extinct species of annual plant in the mint family. Endemic to Guadalupe Island in the eastern Pacific, the Guadalupe mesa mint was only known from a single specimen collected by Edward Palmer in 1875. The species was described from Palmer's specimens by Asa Gray in 1876.
Pogogyne tenuiflora is a small, aromatic annual herb, with inflorescences consisting of flowers in bracteate verticils forming dense terminal spikes. The corollas are blue-purple and tubular, with an erect, entire upper lip and a spreading 3-lobed lower lip. The corollas measure 10–14 mm (0.39–0.55 in) long. The lower pair of stamens measure 3–4 mm (0.12–0.16 in) long. The style is bearded for about 3 mm (0.12 in) below the branches. The two sterile upper anthers place this species within the Hedeomoides subgenus of Pogogyne, which was recognized as its own genus by John Isaac Briquet in 1896.
During his visit, Palmer only saw this species very rarely among the sagebrush habitat on the eastern side of the island.
This brief starts where responsible research should: with the source description of “Pogogyne tenuiflora” as species of plant. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of plant. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated May 8, 2026. The linked authority identifier is Q15353439. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1875, 1876 and 1896.
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.
