Diagnostics:
Very common in unmanaged lawns and scrublands, Kyllinga polyphylla is a upright herb with the distinctive leafy bracts surrounding the inflorescence spike at the tip as with all Kyllinga species.
It can be differentiated from other congeners by its larger size in almost any attribute; from height, its inflorescence spikes, broader and longer involucral bracts, with them also in greater numbers (5-8).
Interesting Facts:
The Greater Kyllinga grows in moist fertile soil, and in the full sun (Swarbrick, 1997). It can be checked and suppressed by cultivation, or from vigorous, well-adapted and well-managed grasses.
