BRYUM DIXONI Cardot.

 dry with a golden gloss, dark brown at base, matted with brown papillose 

 rhizoids. Stem erect, brittle, slightly branched. Leaves small, ovate with 

 short points, narrowly decurrent, imbricated, not twisted when dry, erecto- 

 divergent when moist, concave, margin flat, not limbate, entire, or with

This little moss is very distinct, and remarkable for its short leaves ; its position 

 in the huge genus is probably near to Bryum argenteum. 



Bryum barbatum WILS. Fruit has been found in Norway, and is described 

 by Dr. Hagen as pale yellow-brown, shortly pyriform, contracted below the mouth 

 when dry, the neck longitudinally plicate when dry ; lid yellowish, hemispherical ; 

 orange, lineal-lanceolate, hyaline at point, membrane of endostome half length of 

 teeth, processes fenestrate in middle, cilia 2 3 appendiculate. Male infl. terminal, 

 capitate, bracts large ovato-lanceolate. Arnell regards it as a form of B. elegans 

 var. carinthiacum. 



PHILONOTIS CAPILLARIS Lindb. 



Dioicous; plants very slender, \ \\ in. high, but slightly branched, 

 yellowish-green. Leaves rather distant, somewhat divergent, uniform, 

 from an ovate base, lanceolate, gradually attenuated into a long acute 

 point, minutely serrulate and flat at margin, not plicate, nerve vanishing 

 in the apex ; cells rather lax, papillose. Perigonial bracts erecto-patent 

 ovato-acuminate, acute, nerved to the apex.
