Names
O. R. Holmberg TRIBE LEPTUREAE [family ], in Bot. Not. 1926: 80 (1926); Hansen & Potztal in E.J. 76: 251 (1954)
Information
Perennial herbs, mostly stoloniferous. Leaf-blades narrow; ligule reduced to a ciliate rim. Inflorescence a solitary fragile spike fracturing obliquely, the spikelets alternate (rarely opposite), edgeways on, and embedded in hollows on opposite sides of the cylindrical rhachis. Spikelets 1(–2)-flowered, the florets hermaphrodite; rhachilla produced and bearing a vestigial lemma; lower glume very small or suppressed except in the terminal spikelet; upper glume enclosing the florets, often tailed; lemma 3-nerved, awnless; palea hyaline, about as long as the lemma; lodicules 2; stamens 3; stigmas 2. Grain with large embryo and punctiform hilum; starch grains simple. Leaf anatomy: chlorenchyma radiate; bundle sheaths double; silica-bodies rounded, saddle- or dumb-bell-shaped; 2-celled hairs with swollen distal cell in some species, absent in others. Embryo eragrostoid. Chromosomes small, basic number 9.
Range
One genus; tropical sea-coasts.
Notes
The tribe is distinguished from Chlorideae by the 2-sided fragile spikes and embedded spikelets. It is, however, very similar anatomically, though it is remarkable that there are few anatomical characters of diagnostic importance common to all the species of Lepturus. It is obviously allied to certain genera of Chlorideae such as Oropetium (whose spike fractures transversely).
