The Lycopodium decurrens of Mr. Brown was first referred 
to L. scariosum , Forst. by M. Spring, (Monogr. Lycopod. Pars 
1. p. 108.); and after a careful examination of very many 
specimens with a large suite of those of Forster’s plant from 
various parts of New Zealand and others from Lord Auckland’s 
group, we have no hesitation in adopting that opinion. The 
length of the peduncle, and the presence or absence of the scariose 
white tips to the larger and stipulary leaves, are most variable 
characters in the New Zealand plant ; and though these tips 
are generally absent in the Tasmanian plants, some of the leaves 
show them. The form of the scales of the spike, the breadth of 
their white margin, and the length and form of their white tips 
are no less variable ; the latter are more or less recurved. The 
large common state of L. scariosum has not hitherto been found 
in Tasmania: the climate of the better explored districts would 
appear to be too dry for it. In New Zealand it is common in 
alpine woods of the Northern Island, and throughout the 
Middle and Southern, and it is also found in Chili, among 
the Andes of South America, and in the lofty mountains of 
Jamaica; it is the L. Jussieui , of Desvaux and of Hook. Ic., t.
