GRIMMIACEAE. — 183 
C. Mueller gives no characters in his description of M. lonchomitrium 
to separate it from M. longipes. He states that it is ““ M. longipedi 
simillimum,” but adds that that species has the seta “ arcuato-flexuoso.” 
is, however, is not the case; the seta may be flexuose, but is certainly 
not arcuate, and is fre uently quite straight, and varies in stoutness 
considerably. Original specimens, leg. R. Helms, Greymouth, N.Z., ex. 
rb. C. Mueller, comm. New York Bot. Garden, agree exactly ‘with 
M. longipes. There is no difference in the seta. 
he basal areolation, it may be added, in M. longipes is rather remarkable : 
the cells are rather widely elongate-rectangular, in regular rows, but the 
walls are very incrassate, and the cell-lumen is extremely narrow, almost 
filiform, and instead of being straight and parallel with the longitudinal 
walls it is vermicular, S-shaped, or semilunar, giving a very curious aspect 
to the areolation.

much smaller, of a usually dull olive-green or brown colour, while 
M. longipes is, as a rule—at least, after drying—of a bright-reddish brown.

One of the most distinct of the New Zealand species, from the robust, 
rigid habit, the very acute leaves somewhat spirally twisted, loosely and very 
rigidly, with the points sticking out and bristling, when 
short, stout seta, and elongate, fusiform capsule, plicate throughout its 
length. 
It is a plant of subantarctic distribution (Chile; Auckland, Chatham,
