that it resembles S. tenellum. Milde in Bryol. Siles. p. 393 

 describes another variety simplicissimum, " resembling Hypnum 

 turgescens, the stem swollen, vermicular, quite simple and without 

 branches," apparently some peculiar or imperfect local form.

Note to Sphagnum neglectum. 



I have just received a letter from Professor Lindberg, in which 

 that great bryologist informs me that he has identified Sphagnum 



o 



neglectum Angst, with an original specimen of Sph. laricinum 

 Spruce. This celebrated observer detected the plant in 1846, in 

 Terrington Carr, Yorkshire, and since that time its place in the 

 genus or its title to specific rank have never been settled; Sph. 

 neglectum therefore drops into a synonym, and the species must 

 stand as Sph. laricinum Spruce. 



The Figure 6 x in my Plate, representing a section of the leaf, 

 is erroneous, for the chlorophyllose cells are elliptic and central, 

 just as in Sp>h. subsecundum, to which indeed Sph. laricinum 

 appears to stand in the relation of a subspecies. 



o 



Angstrom described both Sph. laricinum and Sph. neglectum 

 as species in the Ofver. Vet. Ak. Forhandl. for 1865, but Professor 

 Lindberg points out that the Lapland specimens collected by him 

 and published under No. 712 in Eabenhorst's Bryotheca as Sph. 

 laricinum, and also those of Austin's Musci Appalach. do not 

 belong to the species but to Sph. cuspidatum. 



Fine specimens of Sph. laricinum in fruit from the island of 



Aland and Stockholm accompanied the note.
