Barcode number: CDBI 0298288; isotypes: KUN!, PE!)</p><p>Diagnosis.</p><p>Primula daguanensis is morphologically similar to P. epilosa, P. tridentifera, and P. bergenioides in having a stout rhizome, membranous bud scales persistent at thesis, and a similar leaf outline (Fig. 3), but differs by a combination of characters: leaves efarinose, with undulate-dentate margins; adaxial surface smooth; abaxial reticulate veins inconspicuous; lateral veins 5–7 pairs; petiole 1.0– 4.5 cm long; calyx parted to one-third of its length, with broadly triangular lobes; corolla bears an annulus, with lobes truncate at apex and dentate.</p><p>Description.</p><p>Perennial herb, rhizome short and stout, with numerous fibrous roots. Membranous scales present at the base of leaves, oblong, 1.5–2.5 cm long, with glandular hairs along the margin and a foliaceous apex with dentate margins. Young leaves are not yet fully expanded at anthesis. Leaf blades obovate to oblanceolate, 4.5–8.8 cm long, 3.0– 4.5 cm wide, base gradually attenuate and cuneate, decurrent into a winged petiole 1.0– 4.5 cm long; margins undulate-dentate. Leaves coriaceous, efarinose, adaxially smooth; abaxially with glandular hairs along the veins and inconspicuous reticulate venation. Midrib relatively broad, flat adaxially and raised abaxially; lateral veins 5–7 pairs. Scapes 7–12 cm tall, glandular-pubescent; umbel with (2) 4–7 flowers; bracts ovate-triangular, apex gradually acuminate, ca. 4 mm long, margins with glandular hairs. Pedicels ca. 1.8 cm long, glandular-pubescent. Flowers heterostylous. Calyx campanulate, ca. 0.8 cm long, glandular-pubescent, parted to one-third of its length; lobes broadly triangular, apex acute. Corolla purplish-red, ca. 2.3 cm in diameter; with an annulus at the throat; lobes obovate, ca. 7.5 mm wide, apex truncate with dentate. Pin flowers: corolla tube ca. 11 mm long; stamens inserted ca. 6 mm above the base of the tube; style ca. 8 mm long, slightly exceeding the corolla tube. Thrum flowers: corolla tube ca. 14 mm long; stamens inserted ca. 11 mm above the base of the tube; style ca. 4 mm long.</p><p>Etymology.</p><p>The specific epithet refers to Daguan County, Yunnan Province, where the new species was discovered and collected.</p><p>Vernacular name.</p><p>Simplified Chinese: 大关报春; Chinese pinyin: Dà guān bào chūn.</p><p>Phenology.</p><p>Flowering in March; fruiting from April to May.</p><p>Distribution and habitat.</p><p>Primula daguanensis is currently known only from the collection locality, Cuihua Town, Daguan County, Yunnan Province, where it grows on limestone cliffs with running water at an elevation of 1136 m (Fig. 2).</p><p>Preliminary conservation assessment.</p><p>Based on current botanical fieldwork, Primula daguanensis is known only from Cuihua Town, Daguan County, Yunnan Province, and exhibits a highly restricted distribution range. According to the IUCN Red List Categories and Criteria (IUCN Standards and Petitions Committee 2024), it is provisionally assessed as Data Deficient (DD) due to insufficient data. Further botanical surveys in adjacent areas are required to better evaluate its distribution and conservation status.</p></div>	https://treatment.plazi.org/id/6EB2F5A9ADCD5035855C344A38F57457	Public Domain	No known copyright restrictions apply.
