326 BRYACE^E. 



Hab. Marshes and sides of pools, very rare. Scotland (Grant). Fr. summer. 



This is one of the most distinct species of the genus, the rounded, quite obtuse 

 leaves being unique among our species ; B. Marratii and B. calophyllum most nearly 

 approach it, but the leaves are narrower and of a different colour and texture in those 

 plants. 



14. Bryum turbinatum Schwgr. (Mnium turbinatum Hedw.) 

 (Tab. XLIV. B.). 



Densely tufted, tall or short, reddish, robust ; often with long 

 straight innovations bearing sub-equal leaves. Leaves crowded, 

 appressed when dry, gradually large upwards, very shortly 

 decurrent, oval, shortly acuminate , carinate ; margin entire or 

 faintly denticulate at apex, plane or recurved, nerve stout, 

 excurrent in a short point, red ; cells rather large, rectangular- 

 rhomboid, marginal narrow, forming a more or less distinct 

 coloured border. Seta about one inch long, somewhat flexuose, 

 hooked above, rendering the capsule pendulous. Capsule short 

 and thick, when fully ripe turbinate , strongly constricted below 

 the very wide mouth, then ventricose and rapidly tapering into 

 the seta ; lid large, mamillate. Peristome teeth long ; cilia of 

 inner longly appendiculate. Dioicous. 



Var. j3. latifolium B. & S. (Mnium latifolium Schleich. ; 

 B. Schleicheri var. latifolium Schp., Syn.). Tall and very 

 robust, 2-5 inches, with long, straight, almost unbranched, 

 tumid stems ; yellowish green ; leaves very large, roundish oval, 

 concave, sub-obtuse and apiculate, more denticulate and with the 

 border more strongly marked, nerve usually ceasing at or below 

 apex. Capsule longer, on a short seta. 



Hab. Wet sandy places ; rare. The var. P more rare, and very rarely fertile ; 

 Scotland. Fr. summer. 



Somewhat resembling B. pattens in leaf this moss is quite distinct in the fruit, 

 which is shorter, more ventricose, very much constricted below the wide mouth, and 

 'quite symmetrical, not curved nor gibbous. The var. latifolium is a very distinct 

 form, notable for its large wide leaves, so concave that they will not flatten out at the 

 apex ; intermediate forms, however, occur ; I have gathered one with the Rev. C. H. 

 Binstead, in Brecon, as tall and robust as the variety, but with narrower, though 

 equally large leaves.
