diagnosis and figures of the plant. The following descrip- 

 tion has been drawn up from an examination* of the fine 

 series of specimens in the Royal Herbarium at Kew. 



Autoica, flore masculo ut in 0. semdata ; caespilo?>ay 

 caespitibus 2-3 1/2 cent, altis mollibus Qavo-viridibus, 

 caule erecto simplice velob innovationes pseudodichotome 

 ramoso, foliis 3-3 1/2 mill, lon^is paluhs flaccidis laxis 

 siccilate torquatis e basi suberecta vaginante latiore fere 

 1 mill longa ad angulos decurrente elongato-lanceolatis 

 subcarinatis subacutis, margine in parte basilar! revoluto 

 integro superne erecto flexuoso cellulis aculis hyalinis 

 prominentibus dense et minute serrulato^ cellulis in parte 

 basilari hyalinis rectangulis laevibus leptodermicis, in 

 parte superiore chlorophyllosis hexagono-quadratis in 

 utraque pagina mamillari-papillosis, nervo latiore sub 

 apice summo desinente dorso apicem versus spinoso- 

 dentato, foliis perichaetialibus exterioribus caulinis confor- 

 mibus, intimis longius vaginantibus, vaginula cylindrical 

 capsula in pedicello erecto 1/2-1 cent, alto pallido tenui 

 ovato-oblonga vel oblonga 1 1/2-2 mill, longa badiabrevi- 

 colla pachyderma baud striata exannulata erecta vel 

 interdum asymmetrica et curvula, peristomio ut in 



0. serrulatay operculo obtuse rostrato, calyptra cucullata 

 laevi, sporis 17-18 {x diam. 



Species 0. serrulatae (Funk) Schpr. affinissima; ab hac 

 habitu minus condensalo-caespitoso foliis laxis longioribus 

 capsula paulo majore firmiore solum diversa. 



The stem of laxifolla shows a well — marked ^^ cen- 

 tral strand ", as in 0. serrulata, and as in the latter 

 species,* the leaf-nerve is composed of median '' deuter 

 cells, and a dorsal band of stereid cells, — '^ begleiter 

 cells are absent. 



The distribution of 0. laxifoHa is as follows :
