    Type: Russia, Altai Republic, Kosh-Agachsky distr. Chuya steppe, the locality Aktal, bank of the channel of Yustyd R., at the water’s edge and in water, 49°55'N 88°55'E, alt 1838 m, 17 Aug. 2010, A. V. Rodionov, E. O. Punina, N. N. Nosov & A. A. Gnutikov Alt 10-113 (LE!, holotype).
    Plants (11) 20 – 45 (60) cm tall, perennial, with trailing floating or decumbent shoots
    Leaves 2 – 7 mm wide, flat
    Ligules 4 – 5 mm, panicles 3 – 18 cm long, pyramidal but weakly spreading, panicle branches often flexuous or sinuous, perpendicular to panicle axis in ripe condition, 1 – 4.5 cm long
    Spikelets are mainly 1-flowered, rarely 2-flowered on the branch tips, more or less thickly sitting on panicle branches, rounded- or oblong-elliptic. Glumes unequal, lower 0.8 – 1 mm, upper 1.6 – 3 mm long, sinuate on the tip, usually purple, less pinky or light green
    Lemmas and paleas are almost equal, c. 2.5 mm long, glabrous, brownish or light brownish, with narrow hyaline margin
    Anthers c. 1.5 mm
    Fig. 1.
    Catabrosa ledebourii differs from the related C. aquatica s. str. by mainly 1-flowered spikelets, by the less spreading panicle with fewer branching orders, shorter and flexuous or sinuous panicle branches, perpendicular to the panicle axis, often purple glumes and always brown lemmas and paleas (see Table 1). In honour of Carl Friedrich von Ledebour (1786 – 1851), one of the pioneers in Altai flora research, author the first Flora Altaica, published in 1829, and Flora Rossica, published in four volumes between 1841 – 1853, the first complete flora of the Russian Empire. Comparative characteristics of some Eurasian Catabrosa species, growing in the territory of the former USSR are shown in Table 1. 2n = 40
