Observation:—The specimen Beck 24403 ( K, LPB, SI) was previously identified (in herb.) as Chusquea fimbriligulata ( Clark 1996: 338) L.G. Clark in Fisher et al. (2009: 681). This specimen differs from C. fimbriligulata in having a smaller habit (15–80 cm high), foliage leaves (sheath and blade) crowded towards the apex of culm, leaf-blades 8–26 × 1.7–2.6 cm, erect, broadly lanceolate, apex acute, base obtuse, adaxially weakly tessellate on the lower half and not tessellate on the upper half; abaxially not tessellate; fimbriae 5–10 mm long and synflorescence (16–) 21–56 cm with paracladia weakly adaxially pulvinate.
