TARGIONIA 55 
RIccIA FLUITANS L. 
Ricciella flwitans Braun 
The distribution of this species is very similar to that of 
the preceding, being confined to the east side of the country 
south of the Tay. It also occurs in the same kind of 
habitat, as the only form which has been found in Scotland 
is the terrestrial plant R. canaliculata Hoftm. Neither of 
these species is met with except after prolonged drought, 
when the water of the ponds and reservoirs has receded 
below its usual level. Both might be expected to be 
found in Forfarshire. Fruit has been found on the present 
plant in September.

TARGIONIA L. 
TARGIONIA HYPOPHYLLA J. 
This Southern species is very rare, and has been found only 
in a few widely scattered localities. It has not been met 
with in the northern half of the mainland. It is confined 
to warm dry rocks, being most commonly on basalt, but 
occasionally also on conglomerate. Capsules are nearly 
always present. Carmichael, who discovered the Appin 
plant, was the well-known correspondent of Hooker; the 
label on his specimen is not dated.
