![]() The capsule is globose (2.0–3.0 mm long) and is within the calyx. ![]() The flowers are monomorphic, with stamens set just above the cylindrical basal tube, and the style is usually well-exserted from the corolla. The corolla is broad, bell-shaped, and divided into deeply bifid oblong lobes that are 3.0 mm long and erect. The corolla is violet and 8.0–12.0 mm long, and the cylindrical basal portion of the tube is as long as or a little shorter than the calyx on a 1.0–6.0 cm limb. Dissecting two-thirds of its length reveals lobes triangular to lanceolate, and the apex is usually acute. The calyx is typically 2.0–3.0 mm long, open campanulate, five-nerved, glandular, yellow farinose outside, and copiously yellow farinose inside. The bracts can be solitary, lanceolate, or subulate in the range of 1.5–2.5 mm long with yellow farinose the pedicels are 6.0–15.0 mm long and slender with yellow farinose. The scapes are 3.0–6.0 cm tall, usually with one per rosette and a farinose toward the apex bearing one pendent flower. ![]() Leaves are sharply denticulate in the upper half and entire below, of thin texture, somewhat farinose above, copiously covered below with yellow or cream-colored farina, and elegantly veined. They are oblong, obtuse, or rounded at the apex, gradually tapering into a winged petiole, an indistinct petiole, or a petiole that is half as long as the leaf blade. 0.6–1.5 cm long, including the petiole, and 0.3–0.4 cm broad. Leaves in rosettes at flowering time are ca. Stolons 1–4 typically terminate in leaf rosettes and roots, with a farinose of 4.0–10 cm long. ( Figure 1 and Figure 2) is a slender dwarf perennial herb with several thin, stoloniferous, fibrous roots. Primula luquanensis Z.K.Wu and Wei Zhou, sp. ![]() After comparing to relative Primula specimens from key Herbaria (PE, KUN, IBSC, K, E, and P), we confirm that this plant is a species new to science, which we describe and illustrate here. In addition, the plant’s morphology and papery farinose leaves resemble Primula yunnanensis, another species of the same section, but its bell-shaped corolla is easily distinguishable. Its bell-shaped corolla is similar to Primula nutantiflora in the same section, while its smaller growth habit, slender stolon, and relatively fewer flowers suggest a distinct species. Aleuritia Duby (1844:41), marked by moderate or small habit size and hairlessness, usually with farina on the foliage and scape. The plant’s dwarf and hairless habit, as well as its farinose foliage and scape, are indicative of the Primula sect. During a 2018 field survey of Jiaozi Snow Mountain, Luquan County, Yunnan, we discovered a novel species of Primula having a slender stolon, a bell-shaped corolla, and a style which exserted the whole corolla. ![]()
