gated readily from the spores. The chief are D. aspera, D. 

 blechnoides, D. caudata, and D. media. 



DORONICUM. Leopard's Bane. [Corapositae.] Showy 

 hardy herbaceous plants, with large yellow flowers. They are 

 propagated easily by dividing the roots in autumn or spring, 

 and grow in any ordinary garden soil. Except for the 

 variation of the blooming season, there is scarcely difference 

 enough in their appearance to render it necessary to cultivate 

 more than one species. 



DORYANTHES. [Amaryllidacese.] A gigantic half 

 palm-like, half lily-like plant, sending up a scaly stem from 

 fifteen to twenty feet high, bearing at top a vast head of 

 magnificent crimson blooms, much like the individual blooms 

 of the Jacobaean Lily [Amaryllis formosissima), but a little 

 larger. The plant requires loam, peat earth, and dung in 

 equal parts ; is propagated from suckers ; and should be 

 potted in small pots, to be changed, as the plant advances in 

 size, from time to time. It requires a greenhouse or con- 

 servatory : no frost should reach it. It is some years before 

 it attains a size to bloom. We have known it to bloom with 

 greenhouse culture in twelve years ; and no doubt it might be 

 hastened three or four seasons by stove culture, although that 

 would make it more weakly. D. excelsa, twenty feet high, 

 flowers crimson, and is a noble plant. 



DORYCNIUM. [Leguminosse, § Papilionaceae.] Hai-dy 

 and half-hardy perennial and sub-shrubby plants, of small 

 beaaty. Common loamy soil. Propagated by seeds. 



DOSSINIA. [Orchidaceae.] A genus closely related to 

 Ancectochilus, and requiring precisely similar management. 

 D. marmorata is the only species in cultivation : in this the 

 velvety leaves are copper-coloured, overlaid with a network of 

 golden lines. 



DRABA. Whitlow G-EASS. [^''uciferEe.] Hardy peren- 



ji nials of small size, adapted for rockwork, and of very easy 



culture. Increased by division. There are upwards of 



thirty perennial species, all dwarf and suitable for rockwork, 



the flowers mostly white. 



DRAC^NA. [Liliacese.] A genus of fine palm-like 

 shrubs or trees, but for the most part requiring stove treat- 

 ment. Soil, rich fibry loam. Increased by suckers, by side-
