Male plants unknown: fertile plants in rather lax tufts, with stems 2-3 cm. high and 
irregularly spreading-flexuous leaves: stem-leaves 5-7 mm. long, from an ovate base about 1 
mm. long narrowed to a subtubulose point 3-6 times as long, with an entire or slightly denticu-_ 
late apex; costa in-cross-section near the basé with I layer of cells above and 1 below the chloro-
