[The eastern hay-scented fern, Dennstaedtia punctilobula, has reverted back to an earlier name, published in 1827: Sitobolium punctilobulum. Traits that differentiate Sitolobium from Dennstaedtia include a branched rhizome, fronds less than 1 m long, pubescence of hairs with a capitate terminal cell, and a north temperate distribution, while Dennstaedtia species have usually unbranched rhizomes, fronds 1-2+ metres (to 12 metres) long, various types of hairs, but lacking hairs with capitate terminal cells, and a distribution than is primarily tropical.

Taxon 72(1): 20-46 [open access]. This fern is known from talus slopes and acidic soils in s/swNfld. (Bouchard et al., 1991).
