  Sarocalamus Stapleton, Novon 14(3): 346-347 (2004).

  Synonyms: Arundinaria subgenus Sarocalamus (Stapleton) D.Z. Li   

Plants small to shrub-like, spreading widely and forming extensive stands; rhizomes leptomorph. Culms 1–3 m, 0.2–1 cm in diam., tillering to give pluricespitose clumps; nodes level; internodes terete, smooth, not grooved, initially purple-spotted, becoming more uniformly purple after exposure, with light deciduous wax at first. Branches initially 1-3, very erect, appressed, developing promptly within culm sheath, basal internodes often long, secondary branches arching out, often distant from culm, all branches subtended by a sheath; buds initially open at front, prophyll 2-keeled. Culm sheaths persistent; blade small, lanceolate. Leaf sheaths persistent; blade thin, venation tessellate. Synflorescence paniculate, ebracteate, branches erect. Spikelets pedicellate, pedicels glabrous; stamens 3; style branches 3. Name from Saron (Greek, a broom or sweepings), and Calamus (Greek, a reed), as the culms with erect branches are used as brooms in Bhutan, and the genus includes the last few Asian species of Arundinaria that needed to be swept into a new genus.

Sarocalamus is a small genus of approximately 4-6 species, native to the E Himalayas and SW China. They are morphologically closest to Arundinaria, a genus now restricted to species of N America, and closest to Bashania among the Asian genera. Distinguished from Bashania by the longer central branch internodes and the smaller, thinner leaves, and only distinguished from Arundinaria by the narrower spikelets and glabrous pedicels.

Although morphologically very similar to Arundinaria, DNA analysis shows that it is not closely related.
