|discussion=<p><i>Rhynchospora debilis</i> is very similar to <i>R. wrightiana</i> except it has smaller spikelet clusters and more depressed fruit tubercles. It is a common invader of cutover and bulldozed low pineland where it assumes a lowspreading habit, its many culms radiating from the common center much like spokes in a wheel.</p>
