 Dicr. palustre was confounded by all the early British botanists with the 

 fine D. undulatum Ehrh. which is distributed all over the continent, but 

 strangely absent from this country, as is also the still grander D. datum 

 LiND. (Z). robustum Blytt.) , though both might reasonably have been expected to 

 occur here ; both these species resemble D. majus in having aggregated setae. 

 Die. palustre La Pylaie according to specimens in Bridel's herbarium is 

 a form oi Campylopiis flexmsus, and the specimens in the Dillenian herbarium 

 representing T. 46, fig. 16 C. of Hist. muse, belong to D. scoparium and foreign 

 D. undulatum Ehr. (fide Lindberg).
