distinguished by its one- or two-flowered axillary 
‘ peduncles and by its large and conspicuous flowers. 
The plant from which the material for our figure was 
obtained was raised at Kew from seeds received from the 
Arnold Arboretum in 1912. It flowered for the first time 
in 1915; the specimen figured was gathered in 1916. 
Plants continue in flower from June to September; they 
grow vigorously in a loamy soil, give every evidence of 
being hardy in our climate and develop sufficient seeds 
to make propagation easy. As a climbing shrub for 
gardens this Clematis will be valued for the pure white- 
ness and delicate satiny texture of its flowers,
