me to state the changes in affinity that will become necessary in consequence of adopting tins mode of 
arrangement. I wiU only fui-tlier 'mention, that, although the two modes of growth are in general readily 
determined, yet in some cases, especiidly Herbarium specimens, it is a more difficult task. The^ genus 
Woodeia is peculiar, on account of the stipes of the original species having an articulation at a distance 
above the axis of vernation ; nevertheless, as the vernation is terminal, and the bases of the stipes adhe- 
Tont, Woodsia must be referred to Besmohrya.

On aecoimt of some peculiarities in the habit and structure of this species, I have doubts as to the 
proper place it should occupy. Judging by habit, its nearest affinity appears to be with FoJypod^un^ scolopen 
lioideUooV. et Grev., and P. suspensurn, Sw., two species which, with a few others, const^ute a sma^ 
Joup r lated on the one hand to aenopteris, and on the other to Polypodn.n pectrnatun ..^ .U all es ; but 
aZptens erispata differs from those, in having anastomosing as well as free vems, and from P. vulyare m 
ZT^Zn big adherent. For the present I place it in Ctenopteris; but m a general arrangement of 
zts vernation ^ J i ^tall deem it necessarv to characterize it as a separate genus, under the name
