12E063074F475B19B4570B650F8996B8.taxon	diagnosis	Diagnosis. Fargesia nana is morphologically similar to F. fractiflexa and Yushania polytricha, but can be easily distinguished by the shortened culm neck (4 ~ 8 cm vs 13 ~ 40 cm in Y. polytricha), branch complement (10 ~ 20 (30) vs. 1 ~ 5 in Y. polytricha), culm leaf sheath / internode (1 / 3 – 1 / 2 vs. longer than internodes in F. fractiflexa, vs. 2 / 3 in Y. polytricha), culm blade size (0.4 ~ 2 cm × 0.8 ~ 1.7 cm vs. 2 ~ 8 cm × 1 ~ 1.5 mm in F. fractiflexa), auricle (absent vs. falcate auricle in F. fractiflexa), foliage leaf size (5 ~ 7 cm vs. 7 ~ 13 cm in F. fractiflexa, vs. 9 ~ 21 cm in Y. polytricha), foliage leaf sheath length (1.8 ~ 2.2 cm vs. 5.5 ~ 10 cm in Y. polytricha), transverse veins on foliage leaf blade (conspicuous vs obscure in F. fractiflexa and Y. polytricha).	en	Li, Jian-Wei, Wang, Juan, Shi, Ming, Du, Fan (2025): Fargesia nana (Poaceae, Bambusoideae), a new bamboo species from Yunnan, China.

12E063074F475B19B4570B650F8996B8.taxon	description	Description. Rhizomes pachymorph, neck 4 – 8 cm long and 0.6 – 0.8 cm in diameter; internodes 3 – 5 mm long. Culms 1 – 1.5 (2.2) m tall, erect, sympodial, 2 – 4 (6) mm in diameter; culm wall 1 – 2 (3) mm thick, cavity small or solid; culm with 10 – 15 (18) nodes, internodes terete, 10 – 19 (22) cm long, glabrous, without white powder and longitudinal ribs; supranodal ridge more prominent than the sheath scar, intranodes 2 mm tall. Culm buds 5 – 8, without obvious main buds, aggregated into a semi-orbicular composite bud. Culm branches 10 – 20 (30), with slender secondary branches, nearly equal, less than 1 mm in diam., 20 – 40 cm long. Culm leaf sheaths 5 – 11 cm long, 1 / 3 to 1 / 2 as long as internodes, caducous, papery, light yellow-brown, narrow triangular, abaxial surface sparsely brown bristled on upper part, glabrous below; auricles and oral setae absent; ligule ca. 2 mm tall, 2 – 3 mm wide, truncate or lacerated at apex; blade 0.4 – 2 cm long, 0.8 – 1.7 cm wide, reflexed, linear-triangular. Foliage leaves 4 – 6 per ultimate branch; sheath 1.8 – 2.2 cm long, with obvious longitudinal veins, margins without cilia; auricles and oral setae absent; ligule truncate, ca. 1 mm tall, glabrous; petiole 2 – 3 mm long; blade narrowly lanceolate, 5 – 7 cm long and 5 – 7.5 mm wide, apex long acuminate, base cuneate, sparsely gray-pilose adaxially when young, glabrescent, secondary veins (2) 3 pairs, transverse veins conspicuous. Inflorescence and caryopsis unknown.	en	Li, Jian-Wei, Wang, Juan, Shi, Ming, Du, Fan (2025): Fargesia nana (Poaceae, Bambusoideae), a new bamboo species from Yunnan, China.

12E063074F475B19B4570B650F8996B8.taxon	distribution	Distribution and habitat. Fargesia nana was only found in Wuding County, Central Yunnan, China. It grows frequently in relatively humid habitats on steep cliffs at an altitude of 1895 – 1926 m, while coexisting with other herbs and bushes, such as Paradombeya sinensis Dunn, Sunhangia yunnanensis (Franch.) H. Ohashi & K. Ohashi, Heteropogon contortus (L.) P. Beauv. ex Roemer & Schult. Cymbopogon distans (Nees ex Steud.) Will. Watson, Dalbergia yunnanensis Franch.	en	Li, Jian-Wei, Wang, Juan, Shi, Ming, Du, Fan (2025): Fargesia nana (Poaceae, Bambusoideae), a new bamboo species from Yunnan, China.
