terminal on the stem, but becoming intercalary, the bracts and bracteoles similar 

 and like the leaves and underleaves, the lamina deeply concave; antheridia large, 

 spherical, in pairs in the axils of both bracts and bracteoles. Female inflorescence 

 with one subfloral innovation of unlimited growth, thus appearing to be on a 

 short branch, the bracts and bracteoles similar, in three to five series, showing 

 a gradual transition from leaves to the larger, innermost series, the lamina 

 deeply folded, the margins incised to lacinate, the narrow segment-margins un- 

 dulate. Perianth scarcely exserted, deeply folded below, divided to one-half of 

 its length into three, bifid parts, the segments and the margins similar to the 

 margins of the innermost bracts. Sporophyte not seen. Fig. 2. a-k.

 Sendtnera, so to avoid further confusion the collection by Spruce on Mt. Chimborazo is desig- 

 nated as the leetotype of the species.
