Poa maniototo Petrie
Small, compact, greyish perennial, forming intravaginal tufts, <10cm tall, with densely crowded rigid leaves overtopped by slender flowering culms; laminae disarticulating at ligule. Sheaths much wider than laminae, membranous, smooth, nerves distinct, lower sheaths whitish straw-coloured, shining, upper greenish; ligule consisting of 2 flaps at either side of lamina, 0.5-1 mm long, finely ciliate at top and sparsely ciliate abaxially, much shorter across lamina or absent there, usually extending abaxially round lamina as a minutely ciliate rim, to 0.2 mm long; lamina 0.25- 1.5 cm long, stiff, often curved, rolled and up to 0.5 mm wide, grey-green, nerves distinct, surfaces smooth, margins and curved tip scabrous. Culms 1.5-8 cm tall, smooth, longer culms often bearing a single cauline leaf about lh way up. Panicle 0.5- 1.5 cm long, compact, oblong, spike-like, branches and pedicels very short, sparsely scabrous. Spikelets c. 2-3.5 mm long, 3-5-flowered, silky greyishgreen to greyish-purple. Glumes ± equal, 1.5-2- (2.5) mm long, 3-nerved, glabrous; lower glume narrow-elliptic, subobtuse, upper ovate-elliptic, obtuse. Lemma c. 1.5-2—(2.5) mm long, faintly 3- 5-nerved, elliptic, subobtuse to obtuse, ciliate almost throughout with short fine hairs, ± glabrous near tip with wide membranous margins in upper third, rarely glabrous throughout. Palea c. 1.5-(2) mm long, + tangled ciliate throughout. Lodicules 0.2-0.3 mm long. Callus with small tuft of short crinkled hairs. Rachilla minute, c. 0.2- 0.3 mm long, ciliate, projection twice as long. Anthers 0.2-0.4 mm long. Caryopsis c. 0.5-1 × 0.3 mm. 2n = 28. Endemic
Poa maniototo Petrie
Small, compact, greyish perennial tufts, < 10 cm, with densely crowded rigid leaves overtopped by slender flowering culms; branching intravaginal; leaf-blades disarticulating at ligule. Leaf-sheath much wider than leaf-blade, membranous, glabrous, ribs distinct, lower sheaths whitish straw-coloured, shining, upper greenish. Ligule consisting of 2 lobes at either side of leaf-blade, 0.5-1 mm, much shorter or 0 across leaf-blade, finely ciliate, abaxially with sparse minute hairs; usually extending as a rim-like minutely ciliate contra-ligule, to 0.2 mm. Leaf-blade 0.25-1.5 cm, inrolled, to 0.5 mm diam., stiff, often curved, grey-green, glabrous, ribs distinct; margins and curved tip scabrid. Culm 1.5-8 cm, longer culms often bearing a single cauline leaf c. midway, internodes glabrous. Panicle 0.5-1.5 cm, compact, oblong, spike-like; branches and pedicels very short, sparsely scabrid. Spikelets c. 2-3.5 mm, 3-5-flowered, silky greyish green to greyish purple. Glumes ± equal, 1.5-2-(2.5) mm, 3-nerved, glabrous; lower narrow-elliptic, subobtuse, upper ovate-elliptic, obtuse. Lemma c. 1.5-2-(2.5) mm, faintly 3-5-nerved, elliptic, subobtuse to obtuse, shortly finely pubescent almost throughout, ± glabrous near tip or rarely throughout, margins wide membranous above. Palea c. 1.5-(2) mm, ± tangled pubescent throughout. Callus with small tuft of short crinkled hairs. Rachilla minute, c. 0.2-0.3 mm, minutely hairy; prolongation twice as long. Lodicules 0.2-0.3 mm. Anthers 0.2-0.4 mm. Gynoecium: ovary 0.4 mm; stigma-styles 0.75 mm. Caryopsis c. 0.5-1 × 0.3 mm. 2n= 28. Plate 7F.
