1. S. maritimum, Br. fy S chimp. ; pulvinate ; leaves much 

 crowded, erecto-patent, straight, incurved when dry, narrow, 

 lanceolate, with a strong excurrent nerve ; sporangium obo- 

 vato-truncate ; lid very large, shortly rostrate from a convex 

 base ; ring none; teeth cribrose. — Hook. Sf Wils. t. xiii.; Eng. 

 Bot. t. 1645. 



On rocks near the sea, principally those which are quartz- 

 ose, very rarely on those which are calcareous. Bearing 

 fruit in spring. 



Monoicous ; forming lurid or sometimes olive-yellow cush- 

 ions, about an inch high. Leaves rigid, strongly acuminate, 

 but not hair-pointed; margin slightly reflexed at the base; 

 teeth of peristome large. 



2. S. apocarpum, Br. Sf Schimp. ; loosely tufted ; leaves 

 spreading from an erect base, erect when dry, lanceolate, 

 the upper ones hair-pointed ; margin recurved ; nerve slender ; 

 sporangium firm, ovate ; ring none ; lid shortly rostrate ; 

 teeth entire or perforated, dark-red. — Hook. Sf Wils. t. xiii. ; 

 Eng. Bot. t. 1134, 1345, 2226.; (Plate 21, fig. 6) ; Moug. %

On stones, etc., either in dry or very wet situations. Com- 

 mon. Bearing fruit in winter. 



Monoicous ; forming deep-green or at length brownish lax 

 patches. Lid rather oblique, shortly rostrate, from a convex 

 base ; peristome arising deeply within the mouth of the spo- 

 rangium ; teeth large, entire, or slightly pierced, spreading at 

 the base when dry, with the tips erect. 



A very variable species; the leaves vary in direction and 

 breadth, being sometimes, in extreme cases, falcate, sometimes 

 ovato-lanceolate and obtuse, the stems in length and mode of 

 branching, and the sporangium in form ; leaf-cells punctiform 

 above, quadrate or rectangular at the basal disk and extreme 

 angles. R 2
