LiMPEiCHT : Systematic Arrangement of Bog Mosses, 129 



leaves are not enclosed by tlie hyaline, but tbeir disposition is as 

 Lindberg, in his " Manipulus Muscomm sec. (p. 395), so accurately 

 describes. 



This species had already been distinguished by the old bryologists 

 as a distinct form. There are specimens in the herbarium of the 

 Silesian Society collected by Sendtner in Silesia, as S. palustre, var. 

 ^ turgidum, Mart j from the Seefeldern, as palustre, var. y patens, 

 Brid. et var. S. pycrwcladum. Mart., from the Lomnitizer Haide, near 

 Hirschberg. 



Breutel published, in " Musci frond, exsicc," sub. No. 19, S. 

 cymhifolium from Nisky, in the Ober-Lausitz, the first Silesian 

 specimens ; these reach to a length of 30 centimetres,* and are covered 

 with fruit. 



This species does not appear to be particularly rare in Silesia, pre- 

 ferring very damp places. Even upon a short excursion taken a few 

 weeks ago, I collected the plant in our Eiesengebirge, in four different 

 stations, even up to an altitude of 1380 m. f upon the Weissen Wiese. 



The papillae are often less striking, as we find in the " Erb. Crittog. 

 Ital. under No. 1156, S. cymhifolium, which also belongs to S. papil- 

 losum ; and it does not appear to me to be at all improbable also that 

 forms destitute of papilla will herewith be joined in the future. 



Only the sins of carelessness in our botanical excursions, and the 

 slighting of our commonest species, can be the excuse why S. papillo- 

 sum and S. Avstini have so long been overlooked by us. 



To S. papillosum, Lindb., S. Austini, SuUivant, leans closely in 

 many particulars ; the former possesses the referred-to cell-wall 

 papilla, but the latter a slight pectinate thickening, wrongly called by 

 Warnstorf, l.c, p. 139, et 141, papillae. 



Sullivant, in the original description of the plant, has also remarked 

 upon the peculiar disposition of the chlorophyllose cells in the branch- 

 leaves (vide Schimper Syn. Ed. II-, p. 849). 



This species appears with us in general to be rarer, for only a second 

 station is known to me : swampy ditches in the Fasanwalde, near 

 Falkenberg, 0 S. leg. Kern. 



Last year (1880) two new species belonging to the Cymbifolium 

 group were discriminated. 



1. Sphagnum glaucum, Klinggr. Topogr. Fl. Westpr. p. 126 (1880) ; 

 which had already been distinguished as a distinct form, as S, cym- 

 hifolium, var. y squarrosulum, N. ab. E. in " N. & H. Bryol. Germ., p. 8, 

 (1823), and as a distinct species, S. cymhifolioides, Breutsl " Flora,'^ 

 1834, p. 435.
