Jameson's Handbook of British Mosses, p. 416. The species is 

 rare in America and Mr. Dixon has had a much better chance to 

 become acquainted with it, as it is common in England.

There has been an almost endless amount of confusion as to the 

 nomenclature of this plant. Wilson, Mitten, Dixon and Lindberg 

 have applied the name to one plant, and Hedwig, Schimper, Husnot, 

 Limpricht, and Cardot to another. The plant of Lindberg and the 



bryol

Hedwig and Schiraper is identical with our E. hians. Now the 

 two species that have borne this name are utterly and entirely dis- 

 tinct and could not be confused by the veriest tyro. The decision 

 as to what is the true E. praelongum must rest with the Dillenian 

 plant on which Linnaeus founded Hypnum praelongum. Lindberg 

 saw the plant in Dillenius' herbariumt and declares that it is

Lindberg was an acute observer, and has the best possible groum 

 for his opinion, I shall follow him until something more au- 

 thoritative appears. One reason for the continuance of the confu- 

 sion is the fact that the true E. praelongum is rare on the continent

fUndberg's statement is found in his Kritik Granskning af Mossorn uti DiUeB* 

 Historia Muscorum, 17, 1SS3. He gives the following citation from Dillenius' Hist 

 Muse, and herbarium : " 15. H. repens filicinum triangularibus parvis foliis praelon- 

 gum. P. 278, tab. 35. fig. 15. Herb, fol, 93. no. 15." He then adds this note: 

 "Fig. A. Hypnum praelongum I, c. fr. —vera planta, cujus subspecies II- stokes* 1 

 Turn, est nee auctorum recentiorum 1 h. e. II. distans Lindb. )."
