PXLXJLARXA cLOBiJLiEEiiA, Linn, 
Pillwort , or Pepper-grass. 
Gen. Char. Fructifications of two kinds, united in a two- or four-celled 
globose coriaceous radicular involucre , opening by two or four valves at 
the apex : 1, upper ones in each cell ( antheridia :) pyriform, membranaceous, 
containing globose granules; 2, lower ones formed of a membranaceous 
sac enclosing a comparatively large subglobose apiculated crustaceous in- 
dehiscent capsule? [oophoridium) , containing very minute granules, which 
seem to be united in threes or fours.— Partially submerged aquatics. Cau- 
dex slender , filiform, radicant, bearing slender filiform leaves, at the base 
of which are the receptacles.

The stations recorded for this curious plant are not numerous, 
for it is little likely to attract attention. The leaves are slender, like 
those of some delicate Scirpus or Isolepis; and the somewhat 
stouter caudices, yet no bigger than packthread, run along upon 
the watery ground, and bear the globular fructifications on a 
very short stalk close to the soil. So rare was this plant consi¬ 
dered to be in the early part of the late Sir James Smith’s bota¬ 
nical career, that I possess in Gouan’s Herbarium specimens sent 
to the celebrated Professor of Montpellier by Sir James, with 
the remark, “ rarissima planta, tibi ni fallor ignota.” It is how¬ 
ever more common in Prance perhaps than in Britain, and occurs 
in Germany, Sweden, and Norway, and in the middle and south 
of Russia. It does not appear anywhere in the New World;
