[Dr. Braithwaite is at present publishing in the "Monthly Microscopical Journal" a Monograph of this genus, but as he has only got some three or four species described, I regret that I cannot avail myself of his valuable researches, and can only publish such species as are known to me. His division of species is as follows:—
A. 1 S. cymbifolium Ehr. B. 2 S. tenellum Ehr. 3 S. rubellum Wils. 4 S. neglectum Angst. 5 S. subsecundum N. von E. C. 6 S. molle Sulot. 7 S. rigidum. N. H. & S. D. 8 S. squarrosum Pers. 9 S. teres Angst. 10 S. acutifolium Ehr. 11 S. strictum Lindb. 12 S. fimbriatum Wils. 13 S. Lindbergii Schp. 14 S. intermedium Hoff. 15 S. cuspidatum Ehr.] Sect. I. Leaves obtuse roundish or elliptical.
a. Utricles of branches lined with spiral fibres.
10. S. cymbifolium. Ehr. St. 3-12 inches robust tufted solid, covered with a cortical web. Stem l. lingulate-spathulate with a rounded apex; br. l. imbricate broadly ovate concave cucullate and muriculate at apex; caps. large globose on a short seta: dioicous.
Bogs, common. VI. VII.
b. Branch cells without spiral fibres.
11. S. compactum. Brid. St. erect, 2-4in. dichotomous, densely caespitose; branches crowded short, almost erect, br. l. ovate-subulate, obtuse, concave, slightly cucullate and smooth at apex, præmorse with 3-4 teeth; st. l. small elliptical: dioicous.
