26. ANOMODON. 



GEN. CHAR. Frultstalks lateral; Peristome double, 

 consisting 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 ivow included under the present genus cannot cor- 

 rectly be said to have any internal peristome; the narrow pro- 

 cesses 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 anoma- 

 lous species of Orthotrichum will not hold good in the present 

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

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



A. curlipendulum ; leaves ovate, acuminate, serrulate, the 

 nerve disappearing below the point ; fruitstalk twice as long 

 as the perichaetium ; capsule ovate. (TAB. XXII.)

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

 dant in mountainous countries. Rare in the plains; and 

 the only station we are acquainted with in the eastern angle 

 of the kingdom is on the sandy Denes xiear Yarmouth; but 

 it is there always barren. 



There is something very peculiar in the dark, almost 

 blackish grfeen, long, cylindrical, and straggling, though 

 somewhat pinnate stems of this plant. On the wilds of 

 Dartmoor we have gathered them eight or ten inches long, 

 and in a fine state of fructification. The extremities of the 

 branches are slightly incrassated. Leaves imbricated on 

 every side, concave, with a reflexed margin. Those of the 

 peric.haetium very convolute, almost cuspidate, nerve short. 



A. viticidosum ; leaves ovato-lanceolate, obtuse, entire, the
