Leaf-cushions elongated, unbricate, scarcely keeled, directed 
downwards ; exposed portion of cushions rhomboidal or elongated 
transversely ; lateral and upper angles acute, lower angles gene- 
rally rounded. Leaf-scar placed at the summit of the down- 
ward directed leaf-cushion, or only slightly below the summit, 
rhomboidal, or transversely rhomboidal-elongate, lateral angles 
very sharp and pronunent, upper and lower angles slightly roun- 
ded; within the leaf-scar are three cicatricules placed centrally, 
or slightly above or below the centre, the two lateral punctiform, 
the central punctiform, or sub-triangular. When the leaf-scar 
is placed slightly below the apex of the deflered cushion, two 
lines run from its lateral angles, which meet the margin of the 
cushion a short distance below the leaf scar. The leafcushion
