  Fargesia Franchet, Bull. Mens. Soc. Linn. Paris. 2: 1067. 1893.

  Synonym: Sinarundinaria Nakai.   

Tight clumps 7 or more similar branches on smooth culms Small dense inflorescences

Plants shrub-like, densely clumping; rhizomes pachymorph, necks to 30 cm. Culms unicaespitose, to 6 m tall and 2.5 cm in diam., basally erect, apically nodding to pendulous; internodes to 30 cm, terete, usually smooth and not finely ridged, glabrous, finely purple-spotted, rarely with light to dense wax at first, becoming glossy; nodes scarcely to moderately raised. Branches 5--10 per mid-culm node at first, 7--20 later, often above promontory, subequal, initially erect, becoming deflexed, lateral branch axes lacking subtending sheaths; buds at mid-culm ovate to lanceolate, with 2 tall, single-keeled bracts, dorsally fused in lower culm, open at front (closed at culm base), several initials visible. Culm sheaths oblong, shorter than internode, deciduous; blade usually reflexed. Leaf sheaths persistent; blades small to medium-sized, usually glossy and thickened, normally not deciduous, transverse veins prominent. Synflorescence ebracteate or branches subtended by a series of small persistent delicate sheaths, semelauctant, compressed; branching racemose, unilateral. Spikelets few-flowered; glumes 2 basally tight without subtended buds. Lemma obtuse or acute at apex and mucronate to awned. Palea equal to or shorter than lemma, 2-keeled. Lodicules 3. Stamens 3. Style 1--2. Stigmas 2--3, plumose. Caryopsis oblong. Flowering monocarpic. Named after Paul Guillaume Farges (1844-1912), French missionary and naturalist in W China.

Fargesia, a temperate clumping genus endemic to C & W China, currently includes up to about 90 species, but many are misplaced. New introductions from W China are becoming available, but their identification is not always straightforward.

The genus was originally described for a species with a very dense, spathed, unilateral racemose toothbrush- likeinflorescences, and short rhizomes. It has often been suggested that it should be included in the earlier, Himalayan genus Thamnocalamus Munro, which also has rather dense, initially spathed inflorescences. However, bud and branch morphology as well as molecular evidence suggest that they are not so closely related.

For many years all temperate clump-forming species discovered in China were described as species of Fargesia. Many such species were later found to lack dense racemose unilateral bracteate synflorescences, and were moved to other genera, including Himalayacalamus, Drepanostachyum, and Thamnocalamus. A very large number are actually species of Borinda, but it is very hard to separate them without flowers. Most Borinda species have finely ridged rather than smooth culms, and either longer or much tougher culm sheaths. However, because it is still not known which species are really Fargesia and which are Borinda, the two genera are often temporarily treated as one, under the name Fargesia, in order for all the species of Borinda to remain together, e.g in the Flora of China.

The genus Sinarundinaria Nakai was published for cultivated plants of F. nitida and F. murieliae sent from Kew to Japan. Flowering of both species has confirmed that they belong in Fargesia, where Sinarundinaria is now placed as a synonym. Sinarundinaria was for a while used in a very broad sense covering the genera Yushania, Drepanostachyum, Himalayacalamus, Chimonocalamus and Otatea as well as Fargesia nitida, assuming that F. nitida would have open inflorescences, which it does not.
