HAB. On banks and in fields, particularly common in De- 

 vonshire, especially near Torquay and the mountainous coun- 

 try about Tor-point. 



The colour of this plant inclines much to yellow, both in 

 the leaves and fructification ; the former approach in tex- 

 ture those of T. sululata, than which it is much smaller. 



6. T.stellata; stems scarcely any; leaves ovate, concave, nerve 



running beyond the points; capsule ovate, striated, lid 

 rostrate. (TAB. XII.)

HAB. Scotland, Mr. D'ickson. 



This minute plant, which has very much the delicacy of 

 structure and reticulation of the leaves of 7\ cuneifolia^ has 

 been found only by Mr. Dickson in Britain " ad aggeres et 

 rivulorurn margines Scotiae." We have compared some ori- 

 ginal specimens from Mr. Dickson with the West Indian 

 Barbula agraria, sent by the younger Hedvvig to Mr. Tur- 

 ner, and we find them to coincide in every particular : a point 

 indeed already determined by the author of the Muscologia 

 Hilernica. This then appears to be one of the few instances 

 of a plant of the tropics having been found in so northern 

 a region. 



7. T. tortuosa \ stems elongated, branched; leaves lineari-subti- 



late, carinate, undulate, much twisted when dry ; capsule 

 cylindrical, lid rostrate. (TAB. XII.)

HAB. Subalpine countries, principally on limestone rocks. 



This differs from all the British species of Tortulce by the 

 great length of the stems, and by the undulated margins of 

 the leaves when moist, and their remarkably crisped ap- 

 pearance when dry. Barbula inclinata figured in Schwae- 

 grichen's Suppl. comes very near this species: but its stems 

 are short, its leaves nearly linear, and its capsule inclined. 



8. T. fallax ; stems elongated, branched ; leaves lanceolate- 



subulate, patent or recurved, their margins reflexed; cap- 

 sule oblong; lid rostrate, nearly as long as the capsule,
