becoming denser, fibrose, and porose toward the broadly truncate 

 toothed apex. 



Hab. — Deep marshes in the north of Europe, forming great tufts in the water, 

 like islands. Fr. July. 



Europe. — Karesuando, in Tornean Lapland (Lsestadius, 1825) ; Lycksele, in 



O 



Lulea Lappmark (Angstrom, 1858) ; also in Pitean Lapland, between Lakes 

 Skutijaur and Storavaviken, and in many places in Umean Lapland (Angstrom). 

 Finland: At Kajana (Malmgren) ; Ruovesi (Simming), and Sarvivaara, in Ostro- 

 bothnia (Brotherus). Norway : Drivstuen, in the Dovrefjeld (Berggren). 



This fine species has not much affinity with either of those with 

 which it is grouped, nor indeed with any others ; in aspect it most 

 reminds us of Sph. cymbifolncm, from which it is at once distinguished 

 by its toothed branch leaves and non-fibrose cuticular cells. 



It has not yet been found in America.

Pl. xii. 



Monoicous ; in very soft, dense tufts, whitish green above, pale 

 brown below. Stem with 2-3 strata of cuticular cells. Stem 

 leaves large, obovato-spathulate, 3-toothed at apex, very narrowly 

 bordered ; the hyaline cells fibrose and porose in the upper part. 

 Leaves of divergent branches oblong-ovate, convolute above, the 

 apex truncate, with 5-6 irregular teeth ; hyaline cells prominent 

 and confluent at back, the chlorophyllose triangular, projecting 

 between the hyaline at the concave surface of leaf.

Monoicous or dioicous ? growing in soft, densely cushioned tufts ; 

 yellowish green or whitish green above, pale brown below. Stem 

 3—5 in. high, pale green, slender, with 2-3 layers of non-porose 

 cuticular cells, those of the peripheral layers pale yellowish. Stem 

 leaves large, closely set, obovate-spathulate, minutely auricled, 

 patent and deflexed ; the margin involute above, very narrowly 

 bordered ; apex with three teeth and a few smaller ones below ; 

 hyaline cells weakly fibrose in the upper third. 



Ramuli crowded, 3-4 in a fascicle, nearly alike, short, slender, 

 divergent or ascending ; the retort cells elongated, a little recurved 

 at apex. Branch leaves divergent or subsquarrose, oblong-ovate,
