The type of F. elochaet C. M. (Neu Seeland, Beckett, 1892) differs in 
no way from, F. tenellu 
whether it is not more aac a Crenularia. It is, at any rate, extremely 
close to F. papillosus Lac. and F. punctulatus Lac., which belong to 
that section. The cells bear each a rather high single papilla on the 
lumen.

F. pallidus is probably a rare species in see Zealand, but is found 
also in Tasmania and Australia ; pate gir shoe all three countries are 
in the Kew collection. It appears to be common in some parts of 
Australia. It is a smaller plant shah either of the two following species, 
and distinguished at once by the short stems, with pale, yellowish leaves, 
which are not much altered when dry except at their extreme tips, which 
are often: srétvnsaly enrolled. Under the microscope it is easily known by 
the acute leaves, unbordered and with margins almost entire, the small 
ifolius differ at once in the obtuse leaves; F. oblongifolius 
var. capitatus is most like it, but differs in the deep green colour, much 
smaller cells, and stouter nerve.
