 or not forked near the base, with the root-fibres either confined 

 to the lower half or even extending to the higher nodes, the 

 branchings lax or crowded, between pinnate and dichotomous,

 cm. long, with the latéral leaves varying fi'om 2 — 4 mm. long, 

 the edges subentire or more or less distinctly denticulate, or ciliate 

 at the very base, or the upper edge conspicuously cdiate-denticulate 

 towards the base, the upper base whether or not dilated ; latéral 

 leaves of the ultimate branchlets erecto-patent or spreading ; leaves 

 of the upper plane acuminate to long-cuspidate, denticulate to 

 ciliate, the cusp entire or denticulate, not rarely as long as the
