Clematis campaniflora Brot.
Frost hardy, vigorous, deciduous climber with pinnate leaves, the leaflets in groups of three, bearing small, fragrant, lilac flowers in great profusion in terminal cymes in mid to late summer.  To 6m.  [RHSD, Hortus, Hilliers’.]

Horticultural & Botanical History
‘A native of Portugal, first described by Brotero, who found it in hedges, by the road from Oporto to Coimbra.
It is a climbing plant, growing to the height of eight feet or more, with many branches, towards the extremities of which the flowers are produced; with us they come out in the latter part of the summer; they are very delicate, of a clear purplish white.’  [LBC no.987/1825]. 
Introduced to England in 1810.  [JD].  Originally described by Prof. Brotero in 1804 in the Flore du Portugal.  [IH p.78 Vol.2/1855].  The flower in Loddiges Botanical Cabinet appears almost pure white compared with the pale lilac of the Illustration Horticole figure used here.

History at Camden Park
Listed in all published catalogues [T.320/1843].  A plant was presented to the Sydney Botanic Garden by William Macarthur on September 15th 1847 [RBGS AB].

Clematis viticella campaniflora [Macarthur]
Clematis viticella L. x Clematis campaniflora Brot., a hybrid probably raised at Camden.  I have found no specific description of this hybrid.

Horticultural & Botanical History
Many of the garden cultivars of Clematis viticella are actually hybrids, particularly valued for their colourfull flowers and ability to scramble over shrubs or small trees, or even ground cover plants.  [RHSD].  Clematis hybrids, unspecified, are shown growing as ground covers in a bedding arrangement in a figure in Flore des Serres.  [FS p.22/1874]. 

History at Camden Park
Listed in the 1845, 1850 and 1857 catalogues [T.329/1845].  A plant was presented to the Sydney Botanic Garden by William Macarthur on September 15th 1847 [RBGS AB].
