shown at our Exhibitions last year made up of imported 

 crowns. These were all imported fresh this year, and potted 

 many crowns together. It will pay to get them every year 

 if they can be made to form such fine objects as at our Exhi- 

 bitions. Native of North America. 



C. spectabile album. — Resembles the preceding in habit of 

 growth, and is from the same country ; but its large flowers 

 are of a uniform creamy white, and are very attractive.

This in an extensive family, but the two described are the 

 finest I have seen. There are more species in cultivation ; 

 but as they have not yet flowered, it is difficult to determine 

 which they really are. Nearly the whole of the species are 

 well worth growing, for although their flowers are not so 

 large as those of D. grandiflora, they are very handsome, and 

 of easy culture. The following, some of which I have seen 

 growing, though not flowering, are well worthy of attention, 

 being very pretty and interesting subjects for the cool-house : — 

 D. cernua, flowers green and yellow ; D. chrysostachya, golden 

 yellow ; D. cornuta, pm-ple and white ; D. draconis, white and 

 dark blue ; D. graminifolia, azure ; D. lacera, white ; D. longi- 

 cornis, blue ; D. macrantha, large, white, and sweet-scented ; 

 D. maculata, spotted blue ; D. melaleuca, brown and white ; 

 Z). patens, yellow ; D. 2)rasinata, green and reddish purple 

 D. racemosa, purple ; D. rufescens, purple ; D. spathidata, 

 pale blue ; D. tenuifolia, yellow. Many more species might 

 be named ; but enough has been said, I think, to show that 

 we have a rich stock of novelties in store yet. 



The best mode of treatment to be adopted for these 

 plants is to pot them in shallow pans, in some good fibrous 

 peat in a rather rough state, with a Httle silver sand, well- 

 rotted manure, and live sphagnum moss added to it. They
