96 TASMANIA^ BRYOPHYTA, 



CAMPYLOPUS, Bridel. 



Medium-sized plants, erect, simple, or with few dichot- 

 omous branches, often with slender flagellate branches with 

 longer leaves at the apex- Leaves lanceolate to subulate, 

 rarely nearlv ovate, often tipped with a hyaline hair 

 point ; nei'A^e very broad, flat, continuous ; cells small to 

 medium, generally oblong, sometimes rectangular or rhom- 

 boid, rarely almost linear, smooth, basal cells larger and 

 sometimes a patch of enlarged cells, alars, at the basal 

 angles. Seta long, tortuous, burying the capsule in the 

 leaves when young ; capsule equal, or nearly so, often arcu- 

 ate, sulcate when dry, oblong ; lid conico-rostrate ; calyptra 

 short, broad, cucullate, fringed at the base ; peristome 

 teeth cleft half-way into unequal slender legs. 



A natural group readily recognised by the broad 

 nerve, bent seta, and fringed calyptra. Too much trust must 

 not be placed on colour, a,& plants of this genus are particu- 

 larly liable to blacken when subjected to constant moisture. 

 Also habit and condition of hair point are too variable to 

 make them of much value in a key.
