8 ARBORETUM ET FRUTICETUM. BRITANNICUM 
is most ornamental as 
a single plant, trained 
to a rod or to a wire 
frame. As its branches 
are not very decidedly 
ligneous or persistent, 
but consist mostly of 
annual shoots from a 
suffruticose base, and 
are not much branched, 
the plant does not ex- 
hibit a bushy head. It 
thrives best in bog 
earth, kept somewhat 
moist, in which cir- 
cumstance it differs 
from most of the 
woody species of Clé- 
matis. It may be 
increased by layers, 
though not so readily 
as from seeds, which 
it produces in abund- 
ance. This species, C. 
cylindrica, and C. re- 
ticulata, being neither 
very woody, nor very 
luxuriant in growth, 
may all be treated as 
herbaceous plants, to 
be supported during 
the flowering season 
by temporary props. 
Few border plants, in- 
deed, will be found 
more elegant or more 
ornamental when so 
managed. Y. Clématia Vidrna.

Spec. Char., §c. Peduncles 1-flowered. Sepals thin, acuminated, reflexed 
at the apex, with wavy margins. Leaves slender, pinnate; leaflets stalked, 
ovate or oblong, middle one sometimes trifid, | 
floral ones entire. (Don’s Mill.) A deciduous 
climber. North Carolina and Florida. Height 
3 ft. to 5 ft. Introduced in 1802. Flowers large, 
purplish blue, nodding ; June, August. Fruit 
white ; ripe in September. 
DeCandolle describes this species as related 
to C. Vidrna, reticulata, and crispa, and dis- 
criminated it from these. C. cylindrica, he says, 
differs from C. Vidrna, in the segments of its 
leaves being entire and not trifid ; in the flowers 
being blue, not reddish lilac and pale within, and 
twice the size of those of C. Vidérna ; in the sepals 
10. Clématis cylindrica.
