T, Kmx.—On Lycopodium varium and L. billardieri. 971 
Sub-variety 1. Leaves obtuse, imbricate, keeled. 
N 9. Leaves acute, slender, flat, spreading; spikes slightly 
foliaceous. L. umbrosum, R. Br. 
Terrestrial, usually inhabiting mountain woods in the North and South 
Islands ; descends to sea-level in Stewart Island, the Auckland Islands and 
Campbell Islands. 
y. billardieri. 
L. billardieri, Spring. Hook. f. Fl. N.Z., Handbook N.Z. Flora. 
Stems loosely tufted, suberect or pendulous, 2-5 feet long, excessively 
dichotomously branched, midrib indistinct; spikes much branched, tetrago- 
nous, slender, compact, flaccid, scales keeled, broad. 
In lowland woods. Epiphytal or rupestral. North Cape to Southland, 
but of rare occurrence on the east coast of the South Island. 
The most striking form assumed by this variable plant and in its most 
highly developed condition not to be mistaken for any other: pendent 
masses of this plant 5 feet long are often seen in the forests of the North 
Island, and at a short distance present the appearance of green network. 
Under L. varium, in “Flora Tasmania,” vol. ii., p. 156, Sir Joseph 
Hooker states— When it (L. varium) inhabits warmer latitudes it grows 
dependent from trees, is much branched, more slender and flaccid, and 
becomes L. billardieri.” 
0. gracile, 
Stems sparingly tufted, sub-erect, 6'-12" high, very slender, crowded, 
spreading, linear, acute or obtuse. Spikes lax, simple or sparingly 
branched, scales foliaceous, linear, three or four times longer than the 
capsules. i

Westport, ete. 
A very graceful flaccid plant of a pale green hue and differing widely in 
appearance from other forms. 
It is worthy of remark that New Zealand specimens of L. varium do 
not exhibit any close approach to L. selago, as appears to be the case with 
the Australian plant.
