Epilobium parviflorum
species of plant
Epilobium parviflorum, commonly known as the hoary willowherb or smallflower hairy willowherb, is a herbaceous perennial plant of the family Onagraceae.
Etymology
The genus name derives from the Greek words "epi" meaning "upon" and "lobos" meaning "lobe", with reference to position of the petals above the ovary. The specific Latin name of "parviflorum" means "small flowers".
Description
The biological form of Epilobium parviflorum is hemicryptophyte scapose, as its overwintering buds are situated just below the soil surface and the floral axis is more or less erect with a few leaves.
Epilobium parviflorum reaches on average 30–80 centimetres (12–31 in) in height. The stem is erect and densely covered with hairs, especially in the lower part. The leaves are opposite, unstalked but not amplexicaul, lanceolate and toothed, rounded at the base, 4–10 centimetres (1.6–3.9 in) long. The tiny flowers are pale pink or pale purple, 6–7 millimetres (0.24–0.28 in) in diameter, with four petals, eight stamens and a 4-lobed stigma. Flowering occurs from June to August in the Northern Hemisphere. The hermaphroditic flowers are either self-fertilized (autogamy) or pollinated by insects (entomogamy).
Begin with the source’s own compact description: “Epilobium parviflorum” is species of plant. The dossier treats that line as a proposition to test through Epilobium, parviflorum and species, not as a finished interpretation.
Why this record matters
The phrase “species of plant” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 21, 2026. The linked authority identifier is Q159094. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. 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.
