Sterile ; in small compact yellowish-green tufts | — i in. high ; when 

 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 

 a few teeth at apex ; nerve strong, yellowish, continuous or very shortly 

 excurrent; cells somewhat incrassate, shortly rhombic above, longer and 

 quadrate below, the marginal narrow and almost linear. 



Hab. — Rocks in the bed of stream Alt-Sugach, Ben Namain, Argyllshire (Dixon 1898). 



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 ; 

 teett 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.
