Hardy Clematis. 279 



sign of sterility which he stigmatizes as monstrous ; while the amateur ad- 

 mires it as a triumph of art. These flowers resemble somewhat the double 

 anemones and ranunculus of our gardens. 



Clematis Florida with single, and a variety of the same with double flow- 

 ers, of a uniform color, have been known in Europe for a long time. The 

 latter, according to Curtis, was introduced into the gardens of England in 

 1/76, before the species with single flowers observed by Thunberg in the 

 gardens of Japan, where it is indigenous. It was in this region, whence so 

 many ornamental plants have been obtained, that Dr. Siebold discovered 

 the two-colored variety which is known by his name. It was first intro- 

 duced into the Botanical Garden at Ghent in 1829 with C coerulea ; whence 

 they soon spread into other gardens. 



C. Florida Standishi. — Flowers blue, tinted with lilac ; petals moderately 

 thick, large, and veiy well set. Although it has been classed with the 

 species C Florida^ in our opinion it has more analogy with the C patens ; 

 but it is superior to it in the consistency of its petals, which are very firm. 



C. patens [C. azurea grandijlora). — Large flower, clear blue. 



C. patens Amelia ; C. patens amethystina plena ; C patens atropurpurea 

 plena. C. patens candidissima plena. — Flowers of a medium size, white, 

 double, superior to those of C monstrosa. 



C. patens Helena ; C. patens Louisa ; C. patens Louisa fl. pi. ; C. patens 

 lanuginosa ; C. patens Candida ; C. patens pallida. C. patens ?iivea, of which 

 M. Lemoine speaks as follows : " The flowers of this hybrid are as large 

 as those of the C. lanuginosa : their fonn is the same ; but their color is 

 pure white. The stamens are of a yellowish-white. It is produced by 

 crossing C. lanuginosa with C. patens ; with white flowers : it has retained 

 some of the characteristics of both parents, while acquiring a much greater 

 force of vegetation, and becoming much more hardy." 



Clematis yackrnani and C. ruhro violacea. — Messrs. Jackman and Son 

 of Woking, in Surrey, have obtained these two brilliant novelties by fertiliz- 

 ing Clematis lanuginosa with the C. viticella Hendersoni, and by crossing 

 Cle??iatis lanuginosa with Clematis viticella atroruhens. 



These hybrids have preserved the floral dimensions of one parent, while 

 borrowing largely from the color of the other. At first sight, they are iden-
