compressed, coriaceous, dehiscing by a longitudinal slit, placed 
singly on the upper surface of the leaves near their base, or more 
generally at the upper base of imbricated bracts aggregated into 
terminal spikes, which are either sessile or pedunculated. Spores 
small, numerous, with three lines radiating from the apex. 
A large genus of about 100 species, found in all parts of the world. Of the1l 
species indigenous in New Zealand, 3 are widely distributed in both hemispheres, 
6 extend to Australia, 2 of them reaching the Pacific islands as well, the remain- 
ing 1 or 2 are endemic. 
A. Selago. Leaves multifarious. Sporangia at the upper base of unaltered 
leaves at intervals all down the stem.

crowded, erect, subulate-lanceolate, 4—+1n. long .. 1. L. Selago. 
B. Lepidotis. Leaves multifarious. Srorangia aggregated into distinct ter- 
minal spikes, at the uwoper base of bracts differing in shape and size from 
the leaves.
