|discussion=<p><i>Tetraplodon paradoxus</i> is much confused in the literature with <i>T. pallidus</i> (W. C. Steere 1977), although the two are easily distinguished. <i>Tetraplodon paradoxus</i> is cleistocarpous, the setae are longer (to twice as long), leaves smaller and more narrow, and capsules are darker and spindle- or club-shaped, with the hypophysis noticeably narrower than the urn and having fewer stomata. Steere suggested that spore dispersal to fresh dung might occur when the sporophytes are ingested by caribou or muskoxen and the spores subsequently dropped in dung at some other location.</p>
