|discussion=<p><i>Pteris vittata</i> has escaped from cultivation. It is found on almost any calcareous substrate, such as old masonry, sidewalks, building crevices, and nearly every habitat in southern Florida with exposed limestone, notably pinelands. It is scattered throughout Florida and is sporadic, becoming less frequent to rare northward in the coastal plain.</p><!--
--><p><i>Pteris vittata</i> varies exceedingly in size, density of scales on the rachis, presence or absence of hairs on the abaxial costae, and overall color and aspect of the leaf. As a result, it may occasionally bear a resemblance to forms of P. × delchampsii W. H. Wagner & Nauman, the hybrid between <i>P. bahamensis</i> and <i>P. vittata</i>.</p>
