2.5 mm., not plicate, papillae few and small ; nerve serrate, 

 excurrent; margin acutely serrate above; cells linear, only 

 a few broad ones at the angles. Seta 1-2 cm.; capsule 

 rather small inclined, broadly oblong furrowed. 

 On wet ground, Longley. 



Breutelia dlvaricata Mitt. 



Eobust, 5-8 cm., with few irregular branches, not densely 

 clothed with radicles, pale olive green. Leaves ovate-lan- 

 ceolate, naiTowing at the base, tapering to a slender apex 

 2.5 mm., strongly plicate ; nerve slender, excurrent to 

 lost in the apex; margin serrate, external surface minutely 

 papillose ; cells irregiilar from oblong-quadrate to rec- 

 tangular above, linear below, with an ill-defined band of 

 broader cells on the lower margin. When growing in 

 water the stems are slender, very long, the leaves divaricate, 

 dark green, with a broad base and a very excuiTent nerve. 

 Rest not seen. 



Cheshunt, Maria Island, Mt. Wellington. 



Breutelia comosa Mitt. 



Robust, with suberect dichotomous or fasciculate branches, 

 6-12 cm., usually covered for the greater portion with brown 

 radicles. Leaves squarrose, ^^ellowish, glossy, 4-5 mm. 



plicate, lanceolate from a broad geniculate, sheathing base, 

 tapering to a slender apex, surface minutely papillose, 

 margin serrate; nerve slender, continuous; cells rectangular 

 above, linear below, the sheath bordered by 4-6 series of 

 large delicate, colourless cells. Seta 3 cm. ; capsule pen- 

 dulous, oblong, furrowed.

 Leaves squarrose, yellowish, glossy, lanceolate from a broadly 

 sheathing geniculate base, plicate, tapering to a slender 

 apex, 5 mm., papillate; margin serrate; nerve slender, 

 shortly excurrent; cells narrow rectangular to linear above, 

 long linear below, the border of the sheath of 4-6 series of 

 enlarged, quadrate, brown rather incrassate cells. Seta 

 5 cm. ; capsule inclined, narrow-oblong, furrowed. 



Probably only a robust condition of B. comosa with more- 

 rigid leaves, papillae larger, border cells brown, and more 

 incrassate.
