JUNIPERUS, L.— A genus of Coni- 

 fers (Gymnospermous plants), presenting 

 some interesting characters in the Wood, 

 the Pollen, and the development of the 

 Ovules. 



JUTE. — The liber of Corchorus capsu- 

 laris, Willdenow, an East Indian plant be- 

 longing to the family of the Tiliacese, so 

 many of which fm'nish fibrous substances 

 (such as the bast used for matting, the liber 

 of the lime-tree). Jute has a very long, 

 glossy fibre, and is now largely imported 

 into this country, PI. 21. fig. 3 represents 

 the single liber-fibres (see Textile Sub- 

 stances and Liber).

KALLYMENIA, J. Ag. — A genus of 

 Cryptonemiacese (Florideous Algae), fleshy 



Kaulfussia. 

 A sorus. 



membranous sea-weeds of red colour, with 

 ribless leaf-like fronds, having three strata 

 of cellular tissue, the central filamentous, 

 the intermediate of large round cells, the 

 cortical of minute cells in vertical rows. 

 Fructification : spherical masses (favellidia) 

 of spores half immersed in the frond, and 

 tetraspores, which are tetrahedrally subdi- 

 vided, and occur scattered. The two British 

 species, K. reniformis and Dubyi, are both 

 rather rare.

KAULFUSSIA, Blume.— 

 A genus of Marattiaceous 

 Ferns, with curious roundish 

 sori, formed of radiately co- 

 herent sporanges, opening by 

 a slit at the top (fig. 385).

KERONA, Miill., Ehr.— A genus of In- 

 fusoria, of the family Oxytrichina. 



Char. Body covered with cilia, hooks also 

 present, but no styles. 



K. polyporum (PI. 41. fig. 13). Body 

 whitish, depressed, elliptico-reniform, with a 

 row of longer cilia in front below the 

 mouth ; length 1-144". Parasitic upon 

 Hydra. 



Dujardin unites the genera Stylonichia, 

 E., Kerona, E. and Oxytricha, E., in part, to 

 form his Kerona, with the following charac- 

 ters : Body soft, flexible, oval, depressed, 

 with cirrhi or thick non-vibratile cilia, in the 

 form of setae or styles, and with hooks. He 

 admits five species.

KERONIA.— A family of Infusoria (Duj.). 



Char. Body irregularly ciliated, soft, 

 flexible, with a regular row of oblique vibra- 

 tile cilia leading to the mouth, and with 

 cirrhi in the form of styles or moveable, but 

 not vibratile hooks. This family nearly cor- 

 responds with the Oxytrichina of Ehrenberg. 



Found in stagnant, fresh or salt water; 

 some more especially when the water has 

 become decomposed ; also in vegetable infu- 

 sions. 



Three genera : Halteria, D., Oxytricha, 

 D. and Kerona, D. 



KIDNEY. — The kidney consists of its 

 enveloping membranes, and the secreting 

 parenchyma. 



The membranes are two : an adipose cap- 

 sule composed of loose areolar tissue abound-
