34 ENCALYPTA. 



We have not ventured to quote the numerous synonyms 

 just cited, without an examination of authentic specimens, 

 by which we are persuaded they are all correct. This is 

 one of the most common of mosses, and varies much in the 

 length of its sterns; the annotinous shoots sometimes giving 

 the fruitstalk a lateral appearance, which truly never takes 

 place in any known British Tor tula. The figure of the leaves 

 is very nearly the same in all the states of the plant we have 

 seen, and very unlike that of T.fallax. 



. 11. T. convoluta; stems short; leaves ohlong, rather obtuse, 

 nerve not produced beyond the point ; their margins plane 



^ or slightly incurved; perichaetial leaves sheathing, acute, re- 

 markably convolute ; capsule oblong, lid rostrate. (TAB. XII.).

This is by no means an uncommon species, resembling 

 iii its perichaetial leaves T. revolnta ; "but the cauline leaves 

 are totally different, having their margins rather incurved 

 than revolute. The nerve is pale : the stems are small, 

 much branched with innovations : the fruitstalks long in 

 proportion to the rest of the plant, of a pale yellowish colour 

 like Trichostomum pallidum. Hedw. 



14. ENCALYPTA. 



GEN, CHAR. Fruitstalks terminal ; Peristome single, 

 of 16 teeth ; Calyptm campanulate, smooth, en- 

 tirely inclosing the mature Capsule. (TAB. II.) 



The anomaly least to have been expected in this very natun 

 genus was the decided difference that exists in the shape of 

 teeth of the peristome; for while those of E. vu/garis and E. ci- 

 Uata are short and lanceolate, those of E. streptocarpa are fili 

 form, elongated, and by their close approximation almost form- 

 ing a tube. The columella too in this last plant is exserted beyond 

 the tops of the teeth, which we have never observed in the tw<] 

 other British species. _______
