50 THE CRYPT0GA:\IIC flora of KENT. 



North Frith Wood ; Hoicse. Joydeu's Wood, Bexley ; Swans- 

 combe Wood ; King's Wood, near Maidstone. 



Known from the above species by its strongly dentato-ciliate 

 leaves, the upper lobe of which is scarcely half the size of the 

 lower. 



[S. curta, Dumort., which often grows intermixed with *S'. 

 nemorosa, and is distinguished from it by its smaller size and more 

 distant leaves, of which only the upper ones are toothed ; and 

 S. umbrosa, Dumort., which is also a small species, with truly 

 serrate, narrower and more ovate leaves, should be looked for on 

 sand-rocks in Kent.] 



DiPLOPHYLLUM ALBICANS, Ihimovt. Jum/ennamiici albicans, L. 



On damp hedgebanks and woods ; very common. March, April.

 to the High Rocks ; Forster Fl. Tunbr. Hungershall 

 Rocks ; Quary near the Toad Rocks, in fruit in December ; 

 Keston Common, in fruit in April ; Goudhurst. 

 Easily recognised in the barren state by the enlarged quadrate 

 cells of the margin of the leaves. Known from Xardia scalaris 

 by the absence of stipules, and by the contracted mouth of the 

 four-angled calyx. 



[J. (jracilli))ia, not yet found in Kent, appears to differ only in 

 its more slender habit, and in the marginal cells of the leaves 

 never being enlarged.] 



J. PUMHiA, Dumort. 



On rocks and stones by streams and rivers, or in damp shady 

 places. June. E. B. 2230. Brit. Jung. 17. 



Hungershall Rocks, abundant ; .Tenner Fl. Tunhr. 



Known in the barren state from J. crenulata by its smaller size 

 and more ovate leaves : its concave leaves distinguish it from 

 J, lanceolata, and its calyx tapering much at both ends from other 

 species.
