Botanists surveying high-altitude valleys in Uttarakhand, India, have collected fresh specimens of the woolly alpine daisy Leontopodium stracheyi, a species that had not been confirmed in the country by a verifiable herbarium voucher since 1929. The new collections, made in Gunji valley in Pithoragarh district at roughly 3200 metres elevation, close a 95-year gap in the documented Indian record of this edelweiss relative and confirm that it still grows within its historically known range.

The rediscovery emerged during a 2024 botanical exploration of Uttarakhand’s high-altitude regions, when the first author encountered a population of Leontopodium plants growing in several patches in Gunji valley. The collected material was identified as Leontopodium stracheyi (Hook.f.) C.B.Clarke ex Hemsl., a species historically documented from the high-altitude valleys of Pithoragarh but lacking recent voucher-confirmed Indian records. Herbarium investigation traced very few earlier Indian collections, all from Pithoragarh district, with the last collected specimen gathered by G.E. Benham in 1929 from Ralam valley.

The genus Leontopodium, commonly known as edelweiss, comprises 59 accepted species worldwide and is distributed primarily in the alpine and subalpine regions of Central, Southeastern and Eastern Asia, with only two taxa native to Europe. In India the genus is represented by 12 taxa, occurring mainly in the Western and Eastern Himalayan regions. The genus is characterised by star-shaped woolly-white inflorescences in which capitula are surrounded by bracteal leaves in terminal corymbs, monochromous involucral bracts with membranous margins and undivided stereome, functionally male disc-florets, and a dimorphic pappus. These characters readily distinguish it from the closely allied genera Filago, Antennaria and Gamochaeta, which together with Leontopodium form the FLAG clade within the tribe Gnaphalieae.

Leontopodium stracheyi is a perennial, dioecious herb reaching 12 to 60 centimetres tall, stoloniferous, with stout stolons branched from the base. Its stems are erect, sub-woody, usually unbranched and densely covered in stipitate-glandular trichomes. The narrowly oblong to oblong-lanceolate leaves, 17 to 30 millimetres long and up to 50 millimetres in extreme cases, have bases that clasp the stem semi-amplexicaul to almost auriculate, distinctly undulate margins, and a striking contrast between surfaces: the upper side is green and bears conspicuous stipitate-glandular trichomes, while the lower side is densely snow-white tomentose. Each plant bears 5 to 11 crowded capitula in flat-topped terminal corymbs, surrounded by 7 to 12 bracteal leaves that are adnate to the capitula, giving the inflorescence a star-like appearance 2.5 to 6 centimetres in diameter.

The species is distinguished from morphologically similar and nomenclaturally associated taxa by this combination of characters: stipitate-glandular stems and leaves, relatively broad oblong-lanceolate leaves with semi-amplexicaul to almost auriculate bases and distinctly undulate margins, a green glandular adaxial leaf surface, densely white-tomentose abaxial surface, and 3 to 11 crowded capitula surrounded by conspicuous white-tomentose bracteal leaves. Comparative assessment separated it from allied species including L. artemisiifolium, L. franchetti, L. alpinum and L. sinense, and from other Indian Himalayan species such as L. brachyactis, L. monocephalum, L. haastioides, L. himalayanum, L. jacotianum and L. nanum.

The taxonomic history of the species is intricate. Hooker described it in 1881 as a variety of the European L. alpinum, based on collections made by Richard Strachey and James Edward Winterbottom in 1848 from Tola in Kumaon, then at an altitude of 11,500 feet, and by John Scully from Nepal. Hooker himself expressed uncertainty, remarking that the plant appeared to him to be a state of L. alpina drawn up amongst rocks, but a very peculiar one. Hemsley subsequently elevated the variety to species rank in 1894, citing Clarke’s determination of Kew herbarium material. Franchet in 1892 treated it as Gnaphalium stracheyi, emphasising its numerous closely arranged semi-amplexicaul leaves and short rough reddish pubescence, while Beauverd in 1909 treated it as a variety of L. sinense, noting glandular hairs in both but distinguishing L. stracheyi by its exposed stipitate-glandular pubescence and strongly undulate-crinkled leaf margins. These diagnostic characters are also evident in the newly collected material.

Because the original description was based on material whose application needed stabilising, the authors reassessed the nomenclature and designated a lectotype. Six sheets from a single Strachey and Winterbottom gathering corresponding to the protologue were traced across major herbaria, all from Tola in Kumaon, and treated as syntypes. No specimen of Scully’s Nepalese material could be located. Among the six sheets, only K000901969 bears the annotation Leontopodium stracheyi in Clarke’s handwriting, carries the Herbarium Hookerianum stamp indicating it was likely examined by Hooker during preparation of the original description, and is well preserved with all key diagnostic characters. It has accordingly been designated the lectotype, with five other sheets as isolectotypes, under the relevant articles of the International Code of Nomenclature.

Geographically, Leontopodium stracheyi is distributed across the Himalayan-Tibetan region and adjacent southwestern China, with records from Western, Central and Eastern Nepal, Bhutan, Tibet, Qinghai, Sichuan and northwestern Yunnan. In India it has a narrow distribution, known only from the Kumaon Division of Uttarakhand, particularly Pithoragarh district, where it had previously been recorded from five localities: Milam, Nipchang valley in Darma, Tola, Dhauli valley and Ralam valley. The Gunji valley collections add a sixth locality. In Nepal the species has been recorded at elevations of 2200 to 4500 metres, in China at 2000 to 4700 metres in grasslands, thickets, sparse forests and gravelly slopes, and in Bhutan at 3950 to 4250 metres on grassy banks and dry hills. The new Indian population at roughly 3200 metres grows in open grassy subalpine meadows, along the Kali River and near forest margins, consistent with the elevational and ecological range reported from neighbouring countries.

The authors also scrutinised database records. One erroneous distributional record in Plants of the World Online includes Myanmar within the native range of the species, following a checklist that cited a Kingdon-Ward specimen. Verification of the cited specimen revealed a discrepancy between the associated database metadata and the digitised specimen, the latter indicating a collection by G. Miehe from Central Nepal in 1976. In the absence of a verified voucher, the occurrence of the species in Myanmar is considered doubtful. Similarly, three GBIF occurrence records attributed to B. Dickoré from Martoli, Gori, Kumaon in 2004 could not be matched to traceable voucher specimens despite enquiries to the associated herbarium and data providers, so their taxonomic identities remain unverified. The recollected material therefore stands as the first confirmed Indian record with an authentic voucher specimen since 1929.

The long interval between the historical records and the present recollection may reflect limited collecting effort in the remote Himalayan valleys of Uttarakhand and the species’ narrow distribution in India rather than any change in its status. High-altitude regions of Kumaon are remote, have difficult terrain and are seasonally accessible, with a growing season of roughly June to September as alpine areas remain snow-covered for several months. Accessibility and habitat stability are influenced by extreme monsoon rainfall, glacier-related instability and steep terrain that can trigger landslides, flash floods, glacial-lake outburst floods and debris flows. During the field survey, the authors observed habitat disturbances associated with landslides and mudslides, together with livestock grazing and ongoing local and defence-related establishments. Climate change may represent an additional long-term concern, since studies of herbaceous vegetation in the Western Himalaya at 3200 to 3300 metres have shown that snowmelt timing can strongly influence the onset and duration of vegetative and reproductive phenophases. The authors recommend targeted surveys of other historical localities in Pithoragarh to assess the species’ present distribution, abundance and conservation status in India, noting that the newly collected georeferenced vouchers provide an important contemporary reference for future taxonomic, ecological and conservation assessments.
