shape, more deeply and acutely divided, segments spreading, often 

 acute and ao^ain lobate, outer lobe smaller. 



It may be considered by some authorities as only a variety of 

 K. Trichomanis, but as the distinguishing characters are always 

 permanent, I give it as a species.

Dioicous, laxly and thinly spreading, small, pale green in 

 colour. Stems simple or sparing^ branched, delicate, sometimes 

 elongate, attenuate, depauperate, frequently gemmiparous; branches 

 proceeding from axil of stipules ; radicuiose, rootlets few. Leaves 

 distant or approximate, largest near the middle of stem, smaller 

 below, and often near the apex minute and remote, horizontal to 

 patent-divergent, postical margin usually decurrent, oval or oblong- 

 oval, bidentate to about one-tenth, sinus broad, semilunate, seg- 

 ments a little divergent, acute ; texture fragile, lax, cells rather 

 large, 4-, 5- and 6-sided, walls thick, no trigones. Stipules small, 

 scarcely twice as broad as the stem, irregular in shape, much 

 broader than long, bidentate to below the middle, segments diver- 

 gent, lobate to the middle or below, lobules acute, divergent. 



I have seen no perfect (^ or ? ; the drawing of the perianth is 

 from a sketch sent me by Mr. Slater, who found a single one 

 on a plant collected by Mr. Curnow near Penzance. Andrcecia 

 on separate plants, bud-like, small, proceeding from axil of 

 stipules.
