next species, and chlefiy differing by wanting a green line or keel 1 uBol 



onthe'convex side of the beak of the fruit ; but if, as supposed by Mr. j jj^j^ 



M'Laren, both C paniculata and C. teretiuscula occasionally want 

 this keel,' then C, paradoxa. may be viewed as an artificial species 

 referable partly to the one, partly to the other. Root densely tufted, 

 like that of C, paniculata, and the sp'^ke almost as compound. Stems and 

 leaves nearly as in C. teretiuscula; leaves slender rough at the edges, 

 triquetrous at the end. Fruit obscurely stipitate, with about 7 nerves 

 on the convex side, and 9 on the other, all disappearing about the 

 middle. Achene unequally convex on both sides, broadly ovate, 

 pointed with the inconspicuous base of the style, suddenly contracted
