This is found on the mountain districts through this country, and un- 

 questionably it is an uncommon speeies among the Japanese Lycopods. In 

 the general habit, it approaches to L. 8 dago Linn., which occurs also 

 rarely in Japan, but my plant, having the leaves fine and narrower, is more 

 delicate. 



Lycopodium (Subselago) subdistichum Makino sp. nov. 



Stems tufted, with densely fibrous short roots, generally cernuous-pendu- 

 lous, two to four times dichotomously forkod, slender, terete, smooth, pale- 

 green, 2 j-3 mm in diameter at the lower potion, leafy throughout, 15-40 cm 

 long including the upper fertile branches which are sometimes much slender 

 and then attain even 26 cm in length. Leaves 6-ranks, but 4-5-ranks in 

 the superior fertile branches, not dense, moderately shining ; sterile leaves 

 falsely sub-distichous, rather patent between the diameter of 1 j-2 cm, ob- 

 long-lanceolate, even-sided, sub-acute, distinctly attenuated towards the base, 

 somewhat curved downwards, 5-12J mm long, 2-4j mm broad, rather thin 

 and firm, rather rigid when dry, green but a little paler at the back ; the 

 midrib not distinct, slightly, elevated on the upper surface of leaves and 

 obscurely elevated in the proximal part of the under surface but slightly 

 impressed in the distal part when dry ; fertile leaves rather dense and small, 

 but inferior ones gradually pass into the sterile ones, ascending, the inferior 

 ones lanceolate, the superior ones subulate-lanceolate, embracing a spo- 

 rangium on its somewhat dilated base, entire, subacute or obtuse, rather thin 

 and green ; the midrib inconspicuous. Sporangia sessile and solitary at the 

 axils of the fertile leaves, reniform, lj mm long transversely, somewhat 

 compressed, rounded at each end, smooth, pale-yellow ; valves coriaceous with 

 entire margins ; spores minute, powdery, pale-sulphur-coloured.
