opaquish ; they are turned brown by the action of iodine. The 
surface of the frond is broken up into broad shallow, pits, with the 
shreds elevated and forming the gland-like bodies. These are fewer 
and much larger thanin /t. Jostii, which has the surface broken 
up into much smaller pits. The cavities containing the tuber- 
like bodies do not communicate with the pits in the surface.

This species has much the general appearance of some of the 
smallish forms of Riccvia fluitans. It is readily distinguished from 
its congeners by the margined subspinulose-ciliate or dentate frond. 
The cilie or teeth are in a single more or less interrupted row. The 
cellules of the marginal row are frequently like the others here and 
there, but they are mostly elongated and otherwise larger and mure 
hyaline (much as in the leaves of some species of Mnium or Fis- 
sidens).

On wet rocks, Tallulah Falls, Georgia, Lesquerenz. 
Leaves lobed much as in Sarcoscyphus emarginatus ; but the 
areolation (lax) and amphigastria as in Alicularia Scalaris. Stems 
prostrate ; these and the base of the leaves rather copiously radicu- 
lose underneath.

About the size of J. divaricata ; but the leaves are snorter and 
broader in proportion, more patent, more concave, with the lobes 
shorter more obtuse and somewhat connivent, cells a little more 
distant, less quadrate, and less uniform, perianth on a much shorter 
branch, and albescent or very pale fuscous, ete,
