--><p><i>Rhynchospora megaplumosa</i> is local in central peninsular Florida. It often shares habitat with <i>R. pineticola</i>, and it is taxonomically nearest it in series Plumosae. Distinctive are the longer, paler, narrower spikelets, the longer fertile scales, and perianth bristles of <i>R. megaplumosa</i>. In fact, the perianth bristles of <i>R. megaplumosa</i> are the longest known in the series. While the bristles of all other Plumosae are erect, hugging the achene body, those of <i>R. megaplumosa</i> bend outward so strongly that they push away subtending scales; bristles are conspicuously exposed at maturity.</p>
