 thick, yellowish-grey when dry, subterete or rather obtusely quadrangular, 

 grooved when dry, the upper part compound, oblong, roundish or trans-

 to ciliolate; leaves of the branched part heteromorphous; leaves of the lower

 more or less ascending; of the main rachis oblong, subfalcate, slightly 

 inequilateral, subobtuse, obliquely truncate-rotundate to cordate and more 

 or less ciliolate on both sides at the base, entire, but minutely denticulate 

 on the upper side towards the base, the largest leaves 5 6 mm. long 

 and half as broad ; of the branchlets subsimilar, 2 4 mm. long, relatively 

 narrower, contiguous or somewhat imbricated, rotundate-subcordate to 

 -subcuneate at the base, with the lower base provided with 4 short
