360 CLEMATIS 



otit-of-doors at Kew for ten years at least They blossom well in advance of 

 the great lanuginosa group, and are prized on that account. 



Var. BICOLOR, Lindley (C. Sieboldii, Don). In this variety the flowers are 

 "doubled" through the transformation of the stamens into petal-like organs. 

 Whilst the sepals are white, the centre of the flower is purple. A cultivated 

 Japanese variety, introduced in 1837. 



Var. FLORE PLENO, Jacquin^ has the stamens transformed the same way 

 as bicolor, but they are white. 



Neither C. florida nor any of the group to which it gives its name need any 

 pruning beyond the removal of old flowering wood. 



The differences between the type species of the three great groups of 

 garden Clematis may be tabulated as follows : 



A. FLOWER-STALKS WITH TWO BRACTS. 



1. C. florida. Leaves doubly ternate. 



B. FLOWER-STALKS WITHOUT BRACTS. 



2. C. lanuginosa. Leaves often simple, very woolly beneath ; sepals overlapping. 



3. C. patens. Leaves never simple, but three or five foliolate, slightly downy ; sepals 



set apart. 



C. FUSCA, Turczaninow. 



A semi-herbaceous climber, 8 or 9 ft. high, stems angled, downy when 

 young. Leaves pinnate, 4 to 8 ins. long, and composed mostly of five or 

 seven leaflets, which are ovate with a rounded or heart-shaped base, and often 

 long, tapering points, not toothed ; smooth or slightly downy beneath. 

 Flowers solitary on stout stalks, which are \ to i in. long, and thickly covered 

 with reddish brown hairs. The flower has the pitcher shape of the Viorna 

 group, the sepals being f to I in. long, the points recurved ; outside they are 

 reddish brown, woolly. Seed-vessels with tails about i^ ins. long, plumed with 

 yellowish brown, silky hairs. 



Native of N.E. Asia, from Asiatic Russia through Manchuria to the Kurile 

 Islands. It is an interesting but not very ornamental plant, distinct in its 

 group, because of the very short hairy flower-stalks, and the hairiness generally 

 of the flower. It grows very well, and produces abundant seed. 



C. HENDERSONII, Chandler. 



A hybrid between C. Viticella and integrifolia, raised by Henderson of 

 St John's Wood about 1830, and one of the most beautiful of garden clematises. 

 It is, however, scarcely woody enough to justify its inclusion in this work, dying 

 back to the ground level each winter. The stems are slender, 6 to 8 ft. high, 

 the leaves pinnate, and the solitary, slightly perfumed flowers 2 to 2^ ins. across, 

 deep bluish purple, and borne on stalks 3 to 4 ins. long. Sepals four, spreading, 

 | in. wide. This Clematis flowers most profusely from July to September, and 

 if grown in a group, with the stems supported by stakes, makes a very gay 

 display. The parentage of the plant as given above is deduced from its 

 appearance, the habit and foliage resembling C. Viticella, whilst the flower and 

 feathery-tailed seed-vessel are those of C. integrifolia a well-known herbaceous 

 species. 



C. BERGERONII, Lavallee, is of -the same origin as C. Hendersonii. 



C. INTERMEDIA, Bonamy, is a third hybrid between the same parent species, 

 very handsome also, but taking more after C. integrifolia than C. Hendersonii 

 does. The flowers are bluish purple, 2j ins. across, and appear from July to 

 September. The plant is sturdier and shorter than C. Hendersonii.
