Culms pluricaespitose, erect, ca. 4 m tall and ca. 1 cm in diameter; internodes terete, initially green, yellow-green when aged, white strigose when young, glabrescent when old, initially white powdery at infranodal regions but darkened by contamination when old; walls ca. 2 mm thick; pith spongy; supra-nodal ridges raised; sheath scars prominent, corky, with persistent remains of sheath base. Intranodal regions ca. 1 cm high, thinly white powdery but darkened by contamination when old, glabrous. Culm buds solitary, narrowly trullate, yellowish green, upper parts of prophyll margins densely ciliate. Branches one at lower culm nodes, three at mid or upper culm nodes, base appressed to the culm. Culm leaf sheaths thinly leathery, shorter than internodes, tardily deciduous, initially yellowish green with purple stripes, yellow when old, abaxially densely brown setose and white pubescent, margins densely ciliate; auricles and oral setae absent; ligule arcuate, 5–9 mm tall, abaxially puberulent, margins ciliate; blades erect, lanceolate to linear-lanceolate, scabrous, apex acuminate, base slightly narrowed, margins sparsely serrulate. Foliage leaves 2–4 per ultimate branchlet; sheaths leathery, initially white powdery but darkened by contamination when old, glabrous, longitudinal ribs conspicuous when dry; auricles and oral setae absent; ligule very long, 7–17 mm tall, abaxially puberulent, sometimes white powdery, apex acute, margins sparsely ciliate; blades lanceolate, papery, 10–30 × 2–4.5 cm, apex acuminate, base cuneate, slightly oblique or not, serrulate on both sides, secondary veins 9–12 pairs, transverse veinlets conspicuous.</p><p>Synﬂorescences borne on nodes of branches. The unit of inflorescence of the synflorescence panicle-like, with 12–25 spikelets; main axis glabrous paraxially, more or less scabrous distally, densely white powdery, basal internodes 2–5 mm long; short paracladia 1–2, 3.5–7.5 mm long (excluding spikelets), slightly twisted, sparsely white pubescent, white powdery; long paracladia 3–5, 1–5.5 cm long, sparsely white pubescent, with 2–7 spikelets, lower ones usually with two second order long paracladia, sometimes with a subtending bract at base. Spikelets laterally compressed, 2–5.5 cm long; developed florets 2–6, uppermost 1–2 not fully developed; rachilla segment 6–8 mm long, with two longitudinal ridges abaxially, apex inflated, upper and middle parts densely white pubescent; glumes 2, first glume narrowly triangular to lanceolate, 4–7.5 mm long, ca. 2 mm wide near base, abaxially glabrous, 3–4 - veined, apex acuminate, upper parts of margins ciliate; second glume ovate-lanceolate, ca. 10 mm long, ca. 4 mm wide near base, abaxially glabrous, 8 - veined, apex acuminate, upper parts of margins ciliate, white powdery; lemma ovate-lanceolate, 1.2–2.2 cm long, 2.5–8 mm wide near base, abaxially upper parts white pubescent, other parts glabrous, white powdery, 11–14 - veined, transverse veins conspicuous, apex acuminate (rarely emarginate) with an awn, awn 3–5 mm long; palea obviously shorter than lemma, 1–1.4 cm long, 2 - keeled, keels and upper parts of margins white ciliate, 5 - veined between keels, 4 - veined outside each keel, apex acute when young, shallowly bifid when old; lodicules 3, 2–5 × 1–1.5 mm, rhomboid-lanceolate, subequal, margins densely ciliate; stamens 3; anthers yellow when mature, 6–10 mm long; ovary long ovoid, ca. 2.5 mm long, glabrous; style 1, ca 2.5 mm long; stigmas 3, plumose. Caryopsis unknown.</p><p>Phenology.</p><p>New shoots from April to May; flowering from April to June.</p><p>Distribution and habitat.</p><p>This species has been known to be endemic to South Hunan and Guangdong. It usually occurs on top of mountains and grows near streams or on shaded slopes.</p><p>Chinese name.</p><p>长舌茶秆竹 [cháng shé chá gǎn zhú].</p><p>Additional specimens examined.</p><p>China • Guangdong: Guangzhou City, Conghua District, Liuxihe National Forest Park, Wuzhishan, 11 May 2019, N.

(2006 b) and Zhang and Li (2010) cited Acidosasa xiushanensis T. P. Yi as a synonym of P. nanunica . However, according to the protologue (Yi 1992), A. xiushanensis is different from P. nanunica in having reflexed (vs. erect) culm leaf and more foliage leaves per ultimate branchlet (3–6 vs. 2–4). In addition, A. xiushanensis is distributed in Chongqing, which is far from Hunan and Guangdong, the center distribution area of P. nanunica . Thus, the identity of A. xiushanensis needs to be further studied.</p></div>	https://treatment.plazi.org/id/0CA5C303E373533F97053ECC3992099D	Public Domain	No known copyright restrictions apply.
