Shoots pendulous, once or twice dichotomously branched, 15 45 cm.

 slender keel-like crest, the higher leaves growing gradually shorter ; sporo- 

 phylla about V as long as the barren leaves, similar to the barren leaves 

 (conf. Spring), or ovate-lanceolate (conf. Blume). Specimens received on 

 loan from the Leiden Herbarium, gathered in Java (by Blume), have the
