120 BRYUM: 



to say, we are not acquainted with ; at least not with any sa- 

 tisfactorily according with Hedwig's figure and description. 

 According to this latter, its chief distinction from Br. car- 

 neum is to have the capsule " elongatopyriformis." Smith 

 says u elevate;" but then his fructified specimens in Engl. 

 Bot. surely do not belong to the plant at all, for the leaves 

 are obovate, strongly serrated, and the nerve ends in a hair- 

 like point, as in Br. capiltare. 



10. Br. argenteum ; steins branched; leaves closely imbricated, 

 broadly ovate, suddenly and sharply acuminated, subserru- 

 late, very concave, nerve disappearing below the point; 

 capsule ovato-pyriform, pendulous. (TAB. XXIX.)

HAB. On the ground and on walls and roofs of houses, 

 very common. 



This plant has a remarkably silvery appearance, from the 

 upper half of the leaves being scariose and white, whilst 

 the lower part is green. The acuminated points, especially 

 JMJ* when dry, are patent, and resemble hairs. The whole leaf 

 is thin and reticulated, and very different from Br. jula- 

 ceum, with which the foreign authors have confounded it. 



11. Br. Zierii ; stems branched; leaves closely imbricated, more 

 or less broadly ovate, acuminulate, very concave, reticu- 

 lated, entire, nerve running nearly to the point ; capsule 

 clavate, cernuous. (TAB. XXIX.)

This species, so remarkable for the form of its capsule, 

 resembles the preceding in colour and in its large reticula- 

 tion. 



Nerve of the leaf reaching to the point, or leyond it. 



12. Br. roseum'j leaves obovato-spathulate, acute, serrated, un- 



dulate, nerve running to the point; capsule oblongo-ovate, 

 pendulous. (TAB. XXIX.)

HAB. Banks and on heaths, especially in submountainous 

 countries. Rare in fructification. 



The sterns of this fine species are branched below the sur- 

 face of the ground ; the rest of them is at the base bare of 

 leaves ; above the leaves are spread out in a stellated man-
