BRYUM. 319 



The inflorescence is usually synoicous, but occasionally gemmiform male flowers 

 are found, mixed with the archegonia. 



3. Bryum Warneum Bland. (Tab. XLIII. B.). 



Short, tufted, stems with numerous innovations which are 

 sometimes long and slender. Leaves not much crowded, some- 

 what flexuose and erect when dry, widely ovate or ovate- 

 lanceolate, shortly acuminate, with a denticulate, cuspidate point, 

 the greater part formed by the slightly excurrent , reddish nerve. 

 Margin almost plane or very narrowly reflexed ; cells resembling 

 those of B. inclinatum, but wider, shortly hexagonal or hexagonal- 

 rhomboid, the marginal narrower, forming a slender, not very 

 distinct border. Seta long, 1-2^ inches, capsule abruptly 

 pendulous , shortly and widely ovate-pyriform, very narrow at 

 the mouth, lid small ; peristome almost as in B. pendulum ; cilia 

 3-4, very rudimentary or abortive. Autoicous, male flower among 

 the comal leaves ; rarely synoicous. 



Hab. Sandy ground or mud by rivers or seashores. Rare. Fr. all the autumn. 



The peristome in this species is almost exactly that of B. pendulum, and there 

 need be no difficulty therefore in distinguishing it from all the British species except 

 that. B. calophylium, of course, is quite distinct in the very concave, hardly pointed 

 leaves. The leaves in the present species are wider and shorter than in B. pendulum, 

 more shortly acuminate, with the nerve very shortly excurrent, the cells wider, with 

 a, much less distinct border ; the capsule and neck both shorter, the former more 

 widely oval. The time of ripening the fruit is also different. It appears to be some- 

 what intermediate between that species and B. calophylium, through which also it is 

 linked with B. Marraiii.
