2. Kantia Sprengelii {Mart.). 



Junyermania Sjjrengelii, Mart. FI. Crypt. Erlang., p. ];5o, t. ?>, f. 6 (1817). 



Cincinmdus Sprengelii, Dnm. Syil. Jung., p. 73 (1831). 



Ccdypoyeia Trichomanis, var. Sprengelii, Nees Eur. Leb., Ill, p. !) (1838). 



Heteroicous (monoicous and paroicous), cpespitose, medium 

 size, pale to dark-green in colour. Stems prostrate or suberect, 

 simple or furcate, attenuate often at the apex and gemmiparous ; 

 radiculose, rootlets plentiful, proceeding from the base of the 

 stipules. Leaves approximate or imbricate, horizontal or patent- 

 divergent, broadly ovate, apex entire, acute or rotundate or acutely 

 and shallowly bidentate, sinus and segments acute, margin entire ; 

 texture lax ; cells rather large, hexagonal or oblong-hexagonal, 

 walls thin, nucleate granules clinging to the walls making them 

 appear thicker, trigones very minute or absent. Stipules about a 

 fifth to a fourth smaller than the leaves, about twice as broad as 

 the stem, irregular in shape, suboblate to subreniform, bifid to 

 about a third, sinus wide, acute or obtuse, segments spreading 

 acute or obtusate, lobate, outer lobe smaller. Male and female 

 flowers proceeding from axil of stipules, sometimes the two pro- 

 ceeding from the one axil. Perfect fruit and male flowers I have 

 not seen. 



Dimensions. — Stems from ^ to 1 J inch long, "3 mm. in diameter, 

 with leaves 25 mm. wide; leaves 1-6 ram. x 1*2 mm., sinus 

 •01 mm., 1-4 mm. x I'l mm., 1'3 mm. x 1- mm., sinus '01 mm.; 

 cells "05 mm. x '05 mm., "06 mm. x '05 mm., "05 mm. x "04 mm. ; 

 stipules "25 mm. x "3 mm. segments "1 mm., "4 mm. x "5 mm., 

 seg. "2 mm., '4 x '6 mm. seg. 2', '5 mm. x "6 mm., seg. '2 mm. 



Hab. — Growing in patches on damp shady banks, in woods, 

 &c. Somewhat rare, probably often mistaken for Kantia Tricho-

Found on the Continent and in North America. 



Obs. — Distinguished from. K. Trichomams (L.) by the laxer 

 texture of the leaves, the thinner cell- walls, stipules irregular in
