Belle of Woking. A hybrid form: flowers very full and double; sepals purple.
Flowers velvet, double, resembling variety Fortunei, except in the color of the sepals. From Japanese gardens. F.S. 18:1875-6.
Hybrids of this species are: C. venosa, Krampen, see C. Viticella; C. Lawsoniana, see C. lanuginosa.
Climbing only 5 or 6 ft.: leaves simple or of 3 leaflets, cordate-acuminate, woolly beneath: flowers erect on stout stalks shorter than the sepals, woolly in the bud, the largest of the wild species, being 6 in. across; sepals
5 or 6, broadly ovate, leathery, rather flat, overlapping, lavender or bluish gray; center of stamens pale reddish brown; styles plumose. Summer. Native near Ningpo, China. F.S. 8:811. I.H. 1:14. Lav. 1. M. & J. 4. J. F. 4:363. H.F. 1855:1. 1854:225. G.C. III. 29:23. G. I, p. 257. Gng. 5:38. - It is to this species, more than to any other, that the beauty and popularity of the garden varieties and hybrids are due. The finest hybrids, including C. Jackmanii and its section, and C. Lawsoniana, contain more or less of the blood of C. lanuginosa.
Forms of C. lanuginosa are:
Variety candida, Lemoine (C. Candida, Hort.). Like the type, except that the simple leaves and leaflets of the compound leaves are much larger, and the flowers are larger, being 7-8 in. across, and white with a purplish shading around the margins. F.M. 5:310. V. 6:225. - Perhaps a hybrid of C. patens.
Variety nivea, Lemoine (C. nivea, Hort.). Sepals 6-8, narrowish, pure white; anthers pale brown. - Thought to be of same origin as the above variety
alba magna, Jackman. Flowers very large, pure white, with about
6 broad sepals and purplish brown anthers. G.C. II. 3:685.
Lady Caroline Nevill, Cripps. Flowers
often 7 in. across; sepals 6, nearly white, with mauve - colored stripe down center of each. Gn. 46, p. 33. - One of the finest light-colored varieties.
Princess of Wales, Jackman. Flowers
6 in. across; sepals 8, satiny bluish mauve, very broad. G.C. III. 27:53.
Gn. 59, p. 366.
Marie Lefebvre, Cripps. Resembles the last, but has 8 sepals, more pointed, and darker in shade.
Perfection, Froebel. Flowers very large; sepals 8, very broad, lilac-mauve. R.B. 6:193. Sensation, Cripps. Flowers like the type, but with 6-7 grayish blue sepals, 6 in. across.
Madame Emile Sorbet, Paillet. Flowers bright blue. R.H.1878:291.
Madame Van Houtte, Cripps. Late-blooming; sepals pale blue, becoming white.
Madame Thibaut. Flowers very abundant. - Thought to be a hybrid with C. Viticella.
The President, Noble. A rich violet-blue flower
Excelsior, Cripps. Flowers double; sepals grayish purple, with a reddish bar down the center of each. F.S. 20:2055.
violacea. Noble. Flowers violet-blue, 7 in. across. F.M. 1876:217.
Robert Hanbury, Jackman. Sepals bluish lilac, flushed at the edges with red, and the bar slightly tinted with red. Gn. 16:128.
This species has given rise to numerous beautiful hybrids which in many cases are the product of so much intercrossing that it is impossible to recognize the exact parentage. By far the most important group of these hybrids may be classed under C. Jackmanii, which, however, by some is considered not a hybrid, but a species introduced from Japan.
C. Jackmanii, Moore (C. lanuginosa X C. Hendersonii and C. lanuginosa X C. Viticella. C. hakonensis, Franch. & Sav.). Fig. 987. Habit and leaves of C. lanuginosa: flowers flat, 5-6 in. broad, usually in 3's and forming panicles at the ends of the branches; sepals 4-6, very broad, velvety purple, with a ribbed bar down the center; broad, central tuft of pale green stamens.
