However, it can be readily diagnosed by weak, pendulous branches, a markedly elongated inflorescence, and a distinct corolla, viz., the upper lip is bilobed, each lobe has emarginate to bilobed apex, while the lower lip is deeply trilobed with subequal lobes, each lobe possesses a short claw at the base and shallow teeth at the middle of the apex, and the palate is absent.</p><p>Type.</p><p>China • Anhui Province, Anqing City, Qianshan County, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=116.39479&amp;materialsCitation.latitude=30.710243" title="Search Plazi for locations around (long 116.39479/lat 30.710243)">Tianzhushan Mountain</a>, growing epiphytically on the rock wall, 30°42'36.87"N, 116°23'41.24"E, alt. 154 m a. s. l., 27 July 2021, Xin-Xin Zhu, Jun Wang &amp; Mei-Hua Wang ZXX 211303 (holotype HITBC!

Taproot thick, robust, 1.5–4.0 cm long; adventitious roots numerous, shotting from the stem base, slightly woody, dark brown. Stem many-branched, terete, woody and tuberous at base, pendulous, procumbent, 25–40 cm long; old stems rigid, rooting from lower nodes, brownish green, densely hispidulous to glabrescent; young stems slender, ascending, grayish green, with dense, white hirsuteous hairs. Leaves sparsely arranged at base, forming a rosette, often caducous; stem leaves numerous, alternate, fascicled at upper nodes; petioles of lower leaves ca. 0.5 cm long, densely hispidulous, gradually reducing in length upward, upper leaves sessile; leaf blade obovate to obovate-spatulate, 0.8–2.4 cm long, 0.6–1.3 cm wide, apex obtuse, base tapering, margin incised-serrate, teeth callous at apex; adaxially green, subglabrous to sparsely hispidulous, abaxially yellowish green, densely hispidulous; veins conspicuous on both surfaces, convex below and slightly concave above. Inflorescence racemose, many-flowered, terminal and axillary, lax, elongated up to 25 cm long at fruiting; bracts subulate to filiform, 0.6–1.2 mm long; pedicels slender, 0.8–1.4 cm long, with dense, hispidulous hairs and sparse, glandular hairs. Calyx narrowly campanulate, 5.0–8.0 mm long, 10 - veined, densely villous and glandular hairy; lobes 5, triangular-lanceolate, as long as tube, apex acute, ciliate at margin and along veins. Corolla white to pale violet, 1.1–1.4 cm long, with a darker band on the abaxial surface of upper lip, sparsely puberulent to glabrous; tube cylindric, 0.4–0.6 cm long, exserted from calyx; 2 - lipped, upper lip 2 - lobed, upcurved, lobes emarginate to slightly 2 - lobed; lower lip deeply 3 - lobed, lobes subequal, ca. 2.5 × 4.0 mm, obovate, apex round, emarginate or shallowly toothed, base acutely narrowed, forming a short claw; palate absent. Stamens 4, exserted from throat, inserted at the same level near the apex of the corolla tube; didynamous, anterior 2 longer; separated and opposite to lateral lobes of lower corolla-lip, posterior 2 pairwise approached, included in corolla tube; filaments filiform, curved, glabrous, anther 2 - celled, thecae divergent, connivent at apex. Style 0.6–0.8 cm long, exserted beyond anthers, stigma 2 - lamellate; ovary hairy. Capsules enclosed by the persistent calyx, ca. 0.9 × 1.3 × 2.1 mm, ovoid, compressed, apex rostrated, brown, hispidulous; seeds ovoid, small, numerous.</p><p>Phenology.</p><p>Flowering was observed from June to August and fruiting from July to September.</p><p>Distribution and habitat.</p><p>The species is currently known only from the type locality in Anhui Province, China, specifically in the mountainous regions where it grows on steep rock crevices. The habitat is characterized by a mixed forest community, where the population is found in association with species of Acer L., Pinus L., and Miscanthus Andersson.</p><p>Etymology.</p><p>The specific epithet “ unguiculatus ” refers to the lobes of the lower corolla lip forming short claws at the base.</p><p>Vernacular name.</p><p>Simplified Chinese: 爪瓣通泉草; Chinese pinyin: Zhuă Bàn Tōng Quán Căo.</p><p>Provisional conservation status.</p><p>Mazus unguiculatus is currently known only from a single locality in Anhui Province, China. Given the currently limited survey data, the species is provisionally assessed as Data Deficient (DD) according to the IUCN Red List Categories and Criteria (IUCN 2022). Further surveys are needed to clarify its population size, distribution, and potential threats.</p></div>	https://treatment.plazi.org/id/3F515CC8DA375C26AF54ED0B5C7ADF38	Public Domain	No known copyright restrictions apply.
