100 TASMANIAN BllYOPHYTA, 



h bifid, lobes slender, margins imidentate. Perianth 

 cylindric, strongly triquetrous. 



Mt. Wellington. 



Lophocolca iJccolorata, St. — llather robust, pale- 

 Leaves crowded, erect then more plane in older parts, 

 obliquely ovate from a very broad base, truncate with a 

 narrow bidentate apex, 1-2 mm., dorsal margin curved, 

 ventral strongly curved below, lobes broad or narrow erect 

 or spreading, sinus deep. Cell-walls rather thick. Under- 

 leaves hardly broader than the stem, very deeply bifid, 

 lobes slender, margin unidentate. Inner floral leaves little 

 larger, ovate, apex deeply bifid, lobes narrow long at- 

 tenuated. 



Very close to Jj. h/sjj/jiosa and L. <iiixfrn-al pina. 



Mt. Bischoff. 



Lophocohd nioorcdua, St. — Robust, pale. Leaves ovate 

 from a broad base, 2-5 long and wide, apex truncate boldly 

 biypinous, lobes broad at the base, acute, sinus deep, dorsal 

 margin nearly straight, shortly decurrent, ventral strongly 

 curved below ; cell walls thin. Underl eaves twice as broad 

 as the stem, deeply bifid, lobes acute, margin with one bold 

 spine. Inner floral leaves 4 mm. long, oblong-elliptic, apex 

 bifid, lobes triangular, attenuated. 



Doubtfully distinct. 



St. Patrick's Head. 



Lophocolea leucophyUa, Tayl. — Pale green or yellow, 

 much branched and rather rigid. Leaves crowded, con- 

 cave, distichous, triangular from a broad base, 1-2 mm. 

 long, dorsal base decurrent, apex narrow boldly bispinous, 

 margin armed with few or many bold unequal spines. 

 Cells 18-27 /,'.., trigones small rotund, each cell with one 

 convex papilla, but sometimes reduced to a mere convexity. 

 Underleaves rather large and broadly connate on both 

 sides, rcniform, margin armed with about 6 bold spines. 

 Perianth long exserted, large, usually acutely triquetrous, 

 but in some specimens even in the same mass narrowly 

 fusiform. 



L. verrucoiid, St., appears not distinct. 



Common, chiefly on mountains. 



Lopliorolea luurirnta, Nees. — Very small. Leaves 

 plane, about 1 mm., ovate-triangular to l-3rd bifid, lobes 

 broad, sinus narrow, margin armed with a few spines. Cells 

 18 IX., surface armed with prominent papillae. Under- 

 leaves deeply bifid, each margin with a spinous lobe, all 

 lobes acutely dentate. Perianth oblong, triquetrous, mouth 

 copiously armed, surface setulose. 



Common throughout the Southern Hemisphere.
