Rather more robust than R. cristatum, more often yellowish, with 
larger, broader leaves, which are, however, generally narrower at 
points and less obtuse. The seta is often very stout and usually short, 
about half an inch, but in my experience this character is a mu uch 
less defined and practica al one than is usually nee by authors; I 
find it highly variable both in length and in thickness 
t 
is a common species.

Rhacopilum cristatum H. f. & W., Fl. N.Z. ii, 121 (1855) ; Handb.

This i disrypeies a much more slender plant, with delicate leaves 
much an @ n dry, and usually more distant and more oblong 
and obtuse, the joss nerve weaker, but I find some plants very 
difficult to separate, even in the fertile state, as the seta varies much 
in length and thickness. 
The sapien “ awn from the calyptra is probably a good one, but 
is rarely avai 
The distribution is about the same as in the last, but it is probably 
less comm

This may be a distinct ek esi by the tapering, acute 
leaves, at thin , longer seta, which may reach an inch in length; but 
I am doubtful if it is really distinet from the last 
It appears to be rare. 
Rhacopilum robustum H. f. & W., Fl. N.Z., ii, 121 (1855); 
Handb. N.Z. F1., p. 491. 
The most robust species, with the dorsal leaves almost similar. to 
the ietecal, and with a very stout, robust seta and capsule. The leaves 
are very longly aristate. 
Less common than the other species, but found in both Islands.
