and more distantly placed, sometimes leaving the
calyx exposed. Fruit terminal. Calyx large,
oblong ovate, increasing in size upwards, slightly
plicate, mouth contracted and toothed. Calyptra
membranaceous, whitish. Capsule spherical, brown,
longitudinally and transversely furrowed. Flaters
bispiral.

Creeping among spongy peat-like %o\\.~(Plate 2
fig- 29)
Without stipules. Creeping at the base, rhizomatous
shoots entangled, flexuose, polished,
resembling pale brown horse-hair; stems 2-7
mm. long, ascending, terete, rigid, interrupted,
repeatedly innovant, ramuli springing from one
or both sides of the old axis, either barren and
setaceous, or fertile, and with rapidly accrescent
leaves. Leaves on the lower portion of the shoots
and fiagella distichous, approximate, erect, and
appressed to the stem so closely as to be readily
overlooked, ovate, carinate-concave, cleft for half
their length into two lanceolate lobes, sinus acute,
texture thin, polished, punctate-areolate, cells
subquadrate; colour golden brown. Involucral
leaves much larger, vertically spreading, lobes
shallower and more obtuse, half hiding the
perianth. Perianth at first turbinate, when mature
roundish ovate, ventricose, obtusely three cornered
below, mouth contracted, bicristate in front ; in
older specimens multi-plicate, minutely toothed.—
