Monoicous, small, growing in layers of an olive-green 

 color. Stems usually dichotomously branched, with two 

 innovations (rarely only one) arising from immediately below 

 the perianth and adnate to the bracts. Leaves inserted at 

 right angles to the stem or slightly ascending, at an angle 

 of 90 to 80 °, closely imbricate, convex, broadly semi-ovate, 

 rounded or abruptly acute, apex often inflexed, lobule 6—9 

 times smaller than the leaf (usually about 3 times thorter) 

 tumid, oval. cylindrical, unidentate; cells small, roundish, 

 trigenes distinct. Liiderleaves 2V2— 3 times smaller than
