 HAB. Moist banks and in woods, abundant. 

 This little plant has the stems from half a line to full an inch 

 in length, and these are either decumbent, ascendant, or erect. 

 The leaves vary much in their size and figure on the same and 

 on different individuals. In general the superior ones are the 

 longest and of an oblongo -lanceolate form, the lower are much 

 smaller and almost ovate, their margins mostly bounded by a 

 pellucid line ; the nerve is more or less strong, reaching to the 

 point, and sometimes a little beyond it when the leaf becomes 

 apiculate. The colour varies from a deep green, through all 

 the intermediate tints, to a yellow brown. With regard to 

 their insertion they are truly bifarious, distichous in direction, 

 vertical. The structure of the leaves of this and the remaining 

 species of the section is highly curious, and totally unlike that 

 of any other plant with which we are acquainted. Besides 

 being vertical, their upper half, (taking the nerve for the line 

 of separation,) is from the base beyond the middle composed of 

 two equal lamellae, the lower part of which embraces the stem, 

 as represented at f. 4. of D. adiantoides, (TAB. XVI.) and the 

 rest very often embraces a portion of the leaf placed immedi^ 

 ately above it.
