Lyeopodium (Selago) Miyoshianum Makino sp. nov. 



Root fibrous, slender, filiform, scantly branched, issuing from the lower 

 potion of the stem. Stem ascending with a shortly declined base, 7-13 cm 

 high, several times dichotomously forked, elongate, terete, light or often 

 yellowish green, 2 mm in diameter in the thickest one ; branches rather 

 erect, 9-12 mm in diameter including leaves. Leaves rather densely sparse 

 around the stems and branches throughout, uniform, ascending or spreading 

 in the upper and mostly reflexed in the lower portion of the stem, narrowly 

 linear, 4-6-J mm long, -J - f mm wide, a little curved upwards, entire, 

 gradually acuminate with a fine point, sessile and continuous with the 

 stem, thickish, the upper surface nearly plane but a little convex in the 

 inferior ones, the under surface somewhat convex, rather glossy, not firm 

 in living specimens but moderately rigid when dry, green or yellowish green ; 

 midrib not conspicuous. Sporangia placed singly in the axiles of unaltered 

 leaves in the upper part of the branches, very shortly dedicellate, broader 

 than the leaves, 1 mm long transversely, semilunar- or semiannular-reniform, 

 rounded-obtuse at both ends, slightly compressed, the front edge rounded, 

 smooth, pale-yellow; valves rather thin and nearly coriaceous, not firm, 

 with the entire margins ; spores minute, numerous, pale-sulphur-coloured, 

 somewhat compressed. The upper portion of the branches often bears 

 flattened buds which are articulated with the pedicels.
