HAB. On the ground in all parts of Britain. f3. New 



Forest, Hampshire. C. Lyell, Esq. 



This possesses by far the largest leaves of any British species, 

 although the stems are extremely short and unbranched ; but 

 they are sometimes furnished with innovations. The leaves are, 

 moreover, succulent, pellucid in their lower half, curled when 

 dry. The nerve is more or less protruded beyond the acumi- 

 nated extremity of the leaf, but we have never seen it dia- 

 phanous. The capsules are long, cylindrical, sometimes, 

 especially when old, curved ; the lid long, subulate ; the peristome 

 also long, forming a bright red tube ; the teeth, or cilice, free 

 only at the end, when they form a twisted sort of brush. In 

 habit, as well as in place of growth, it has much affinity with T. 

 cuneifolia. 



f f Teeth of the peristome almost entirely free. 



9. T. unguiculata ; stem elongated branched, leaves oblongo-lan- 



ceolate subcarinated obtuse apiculated the margin slightly 

 recurved, capsule oblongo-ovate, lid long rostrate. (TAB. 

 XII.)
