Anomodon.-} DIPLOPERISTOMI. 137 



XXVII. ANOMODON. 



GEN. CHAR. Fruitstalks lateral; Peristome double, con- 

 sisting of 16 teeth, and a ciliary process arising from 

 each tooth; Calyptra dimidiate. (TAB. III.) 



Whilst the true Neckerce have the ciliary processes arising from 

 an internal membrane, as in the Leskece of Hedwig, the two 

 British species, now included under the present genus, cannot 

 correctly be said to have any internal peristome ; the narrow 

 processes, corresponding to those of double fringed mosses, 

 arising from the very same range, and by the sides of the teeth, 

 as is the case with most of the Orthotricha. Since, however, 

 the species which compose the genus in question have nothing 

 in their habit in common with the genus Neckera, with which they 

 have been hitherto united, the argument for keeping together the 

 anomalous species of Orthotrichum will not hold good in the 

 present instance ; and we have thought it right to bring the two 

 following plants into a genus, which we have called Anomodon. 



1. A. curtipendulum; leaves ovate acuminate toothed the nerve 

 disappearing below the point, fruitstalk twice as long as the 

 perichsetium, capsule ovate. (TAB. XXII.)

 HAB. Upon the ground, and on rocks and trees. Abun- 

 dant in mountainous countries ; rare in the plains ; the 

 only station we are acquainted with in the eastern angle 

 of the kingdom, is on the sandy plains near Yarmouth ; 

 but it is there always barren. 



There is something very peculiar in the dark, almost blackish 

 green, long, cylindrical, and straggling, though somewhat pin-
