<ul><li>a soil disc 2.2 × 2.0 m: a gentle litter heap of 60 mm, a lobed rhizome hummock heaving 120 mm more under the clump (gaussian radius 0.36 m), and a collar of soil heaped round every culm's foot, rolled down to the floor at its rim;</li><li>five rhizome knuckles breaking the soil: short, fat, jointed sausages, 1.15 times their culm's foot radius, each running in to an outer culm's foot, their axis sunk 0.32 of their radius under the soil the whole way so they are bedded along their length;</li><li>seven culms rising from a rhizome mass about 0.6 m across, 2.71 to 4.55 m tall above the soil and 4.6 to 7.4 cm across at the first node. Each outer culm leaves the soil already leaning 7° out from the clump's centre, then leans further and arches, swaying a little about its bearing. A culm is buried 45 mm in the soil, flares at the foot, tapers to 0.57–0.60 of its foot radius at the last node, and above it thins fast into a fine whip. Culm sections are ten-sided. Tone runs from a fresh, deep-green culm heavily powdered with white wax just under every node to an old one gone yellow;</li><li>99 nodes, 11 to 18 a culm. A node is a raised ring (a six-point profile revolved about the culm: crest 3.5 mm proud of the wall, inner wall 3 mm inside it), a collar darker than its culm with a pale sheath scar on its crest. Internodes are close at the foot, long through the middle and close again toward the tip: mean pitch 0.249–0.257 m a culm, the middle third 0.079 to 0.106 m longer than the first;</li><li>21 papery culm sheaths still clasping the lowest three nodes of each culm: a sleeve wrapped from just above the node's ridge, its inner wall bitten 1.5 mm into the culm, thinning from 2.6 mm proud at its foot to a ragged, diagonal top whose lip curls off the culm;</li><li>107 leafy branches. Every node from 30% of the way up carries a first branch, turning round the culm by the golden angle; above 42% a second, shorter and flatter one often joins it, and above 62% nearly always. Each is a six-sided slender stem that springs up at 44–78° and arches over by its own sag, so some ride high and some hang. The top node's branch rises nearly upright and plumes the whip. Leaves number 6–12 on a first branch and 4–7 on a second, more toward the crown, and each branch's leaves share a length and a droop, so tufts differ from each other more than leaves in a tuft do: 815 slim, pointed blades in all, diamond-section with a pale midrib and strawy tip;</li><li>three young shoots in overlapping sheaths pushing out of the soil beside the clump (0.27–0.62 m), their husks stepping out at each sheath edge and greening at the tip;</li><li>36 dry leaves and five fallen culm sheaths lying in the litter, off the hummock. Each is a thick lens with its belly 1–2.5 mm under the soil and its flanks leaning 11–15° (sheaths 10–14°), steeper than the soil's slope where litter is laid (outside 0.44 of the disc's radius), so no flank can lie in the soil's own plane.</li></ul>
