transferred it to the latter. Warming regards it as distinct 
from any of these genera, and has done me the honour to 
name it after me. As mentioned above, I regard it for the 
present at any rate as generically distinct. It shows many 
points of difference from other Podostemaceæ, e. g.^ the 
curious erect secondary shoots with the 4-ranked decussate 
leaves, bilobed circumscissile spathe, the long leafy axis 
which is almost certainly the primary, and several charac- 
ters of the fruit. It would appear to be an old and rather 
isolated form.

Fruit isolobous 12-ribbed, or anisolobous 8-ribbed, or 
smooth, dehiscent, with go seeds. Thallus closely attached 
to rock, crustaceous or branched ; secondary shoots with 3-8 
bracts, usually prostrate, and with boat-shaped spathe split- 
ting only or mainly on upper side. Stigmas often dentate 
or lobed. 
Flower on emergence from spathe erect or nearly prostrate, stalked 
or sessile. Stamens 2 or 1, equalling or exceeding ovary. Pollen 
didymous. Ovary more or less globose ; stigmas usually rather large, 
subulate or lobed or dentate, sometimes obcuneate, entire or lacerate.
