Wahlenberg's specimens some difference exists in the leaves, 

 those of W. heteramalla being shorter, with a broader base, 

 thicker nerve, and less secund position, yet we possess in- 

 dividuals which seem exactly to unite those two appearances. 



DIPLOPERISTOMI (PERISTOME DOUBLE.) 

 XXIII. FUNARIA. 



GSN. CHAR. Fruitstalks terminal ; Peristome double, oblique ; 

 the outer of 16 teeth, the inner of 16 teeth, opposite to 

 those of the outer. (TAB. II.) 



The genus Funaria, although sufficiently characterised by the 

 interior teeth or cilise being oblique, and placed opposite to those 

 of the outer, is farther remarkable by these teeth lying horizon- 

 tally over the mouth of the capsule ; and the mouth itself is not 

 situated at the apex of the capsule, but a little below it, as in Bar- 

 tramia. The capsule is obconical or pyriform, somewhat gibbous 

 above, striated when old. The calyptra is mitriform, quadrangu- 

 lar in a young state, much swollen at its base, so as to be ampul- 

 laceous when old; the point mucronated. In the male flowers 

 (of Hedwig,) the succulent filaments are remarkably clavate, 

 jointed, pellucid, the joints containing greenish granules. 



1. F. hygrometrica; leaves very concave ovate apiculate entire 

 nerve excurrent, fruitstalk curved flexuose. (TAB. XX.)
