RAXUXCULACE.^. 1 5 



of bright gentian blue. A very fine sort, flowering with great 

 profusion from June to September. It is one of the best for 

 pegging, its medium, strong, and rather flexible stems being 

 more favourable to the mode than those of more rigid habit. 



D. grandiflorum {Large-floii<e7'cd D.) — This is another of the 

 old species. It grows 3 or 4 feet high, with erect branching 

 stems. The racemes are rather open, the flowers large and 

 intense dark blue. Flowers from June throughout the summer 

 and autumn. Native of Siberia. 



D. grandiflorum flore - pleno differs from the preceding 

 mainly in the flowers being double ; but the growth is scarcely 

 so tall and rather more rigid, and the racemes are more dense 

 and cylindrical. 



D. grandiflorum album difters from the species only in the 

 colour of the flowers, which are white instead of blue, but not 

 a good white. 



D. Hendersoni {Henderson's JD.) — This sort is of garden 

 origin. It grows about 2}^ or 3 feet high, producing fine ra- 

 cemes of bright-blue flowers. Like Fo7'moswn^ it is one of the 

 most useful for pegging dov\-n. 



D. Hermann Stenger. — This is a very handsome sort, also 

 of garden origin. It is rather a robust grower, reaching the 

 height of about 4 feet, producing fine racemes of blue and rose 

 double flowers. It is distinct in colour, and flowers in July 

 and August. 



D. hybridum {Hybrid D) is a tall hairy species, with erect 

 stems, and much and finely cut leaves. The racemes are long, 

 compact, and cylindrical, and the flowers light blue. Flowers 

 from June to September. Height about 4 feet. Native of 

 Siberia. 



D. hybridum flore-pleno difters from the species in no other 

 respect than in having double flowers. 



i). magnificum. — In habit, style of inflorescence, and form 

 of flowers, this sort resembles Bella donna, but the flowers are 

 deep brilliant gentian or purplish blue. Height about 4 feet. 

 Garden hybrid. 



D. pulchrum. — This is a single-flowered pale-blue sort of 

 great beauty. It grows about 2 or 3 feet high, and produces 

 its flowers in June, July, and August. Of hybrid origin. 



D. ranunculifolium flore-pleno. — This sort grows about 4 

 feet high, with long striking racemes of azure-blue flowers, very 

 double. Flowers in June, July, August, and September.
