Diese zarte, niedliche Art hat einige Aöhnlichkeit mit der kleinen rothen, immer steril vor- 
kommenden Form von Sph. acutifolium, welche in den Vogesen gewöhnlich zerstreut unter 
Sph. molluscum angetroffen wird. 
Die constant geringere Grösse und grössere Zartheit, der zweihäusige Blüthenstand , die 
breiteren Astblätter , das Fehlen der Fasern in den grösseren Stengelblättern , unterscheiden 
diese Art hinlänglich von dem ihr übrigens sehr nahe stehenden Sph. acutifolium. WıLson 
sagt: «Some small barren varieties of S. acutifolium are at times difficult to be distin- 
guished from S. rubellum, but in them the leaves are always tapering in the upper half, 
not truly elliptical as in this moss. »
