Hedlundia hybrida
species of plant
Hedlundia hybrida (formerly Sorbus hybrida), the Swedish service-tree, Finnish whitebeam, or oakleaf mountain ash, is a species of whitebeam native to Norway, eastern Sweden, south-western Finland, and locally in Latvia.
Description
Hedlundia hybrida is a medium-sized deciduous tree growing to 10–15 m (33–49 ft) tall with a stout trunk up to 60 cm (24 in) in diameter, and grey bark. The crown is columnar or conic in young trees, becoming rounded with age, with branches angled upwards. The leaves are green above, and densely hairy with white hairs beneath. 7–12 cm (2.8–4.7 in) long and 5–8 cm (2.0–3.1 in) broad, the leaves are lobed, with six to nine oval lobes on each side of the leaf. These lobes are broadest near the base with the two basal pairs of lobes cut right to the midrib as separate leaflets, rounded at the apex, with finely serrated margins. The autumn colour is dull rusty brown. The flowers are 20 mm (0.79 in) in diameter, with five white petals and 20 yellowish-white stamens; they are produced in corymbs 6–11 cm (2.4–4.3 in) in diameter in late spring. The fruit is a globose pome 7–12 mm (0.28–0.47 in) in diameter, bright red, maturing in mid-autumn. The fruit is succulent, and eaten by thrushes and waxwings, which disperse the seeds.
This brief starts where responsible research should: with the source description of “Hedlundia hybrida” 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 Oct 3, 2025. The linked authority identifier is Q41202362. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
