|discussion=<p><i>Ptychostomum weigelii</i> is a common arctic-boreal to north-temperate species in wet sites, easily identified by the broad, long marginal decurrencies of the leaves that nearly reach to the next leaf. Leaves of the similar <i>P. cyclophyllum</i> and <i>P. turbinatum</i> are either not decurrent or only produce short, very slender decurrencies. Plants of <i>P. weigelii</i> from Colorado are pinkish red.</p>
