Primary root tapering downwards, flexuose, 

 slender, with slender lateral rootlets, perennial.

 late, entire, minutely cuspidate, glabrous, light 

 green, with a difficultly discernible midrib, 2*75- 

 3-5 mm. long including the petiole-like base,

 glabrous, but roughened with numerous small 

 colourless elevations, leafy; 1st and 2nd inter-

 long ; the rest generally very short with the leaves 

 close together. 



Leaves simple, entire, cauline, alternate (the

 other discernible venation in the fresh state, 

 scaberulous or minutely ciliate at the margin with 

 colourless hairs or short points, otherwise gla-

 channelled above, thickened at its insertion on
