THE FLORAL WORLD AND GARDEN GUIDE. 285 



Those also which do not bloom must be put by, but all that are 

 utterly worthless should, of course, be destroyed. Such as are to be 

 preserved over the winter should be placed in a light position and 

 kept rather dry at the roots towards the autumn. In the spring 

 prune them moderately, reduce the ball of soil, and repot. The 

 second season there will be no difficulty in determiuing which are 

 worth keeping. To avoid unnecessary labour and to make way for 

 other seedlings, I would strongly advise the amateur to destroy all 

 that are not equal to those already in cultivation at the earliest 

 moment possible. 



NEW STOVE AND GREENHOUSE PLANTS. 



Br GEOKOE GORDOS". 



HE liberal prizes offered at the great exhibitions held at 

 the Crystal Palace, Manchester, and South Kensington 

 this season, served a very useful purpose in bringing 

 prominently before the public the most promising novel- 

 ties introduced by the principal nurserymen, who devote 

 special attention to this branch of their business. The prizes offered 

 were liberally responded to, and a considerable number of new 

 plants were staged, and an excellent opportunity afforiled for pur- 

 poses of criticism and comparison. There is this season no lack of 

 novelties, and the majority appear to be of exceptional merit in their 

 several classes. But unfortunately the plants now in course of 

 distribution for the first time consist almost exclusively of those 

 requiring the temperature of a stove for their successful cultivation. 

 This is to be regretted, as it limits the area of their cultivation, 

 and places them quite beyond the reach of the majority of amateur 

 cultivators. 



Oechids are but sparingly offered, and these few are exceptionally 

 good. One of the best of these is Odontoglossum Roezli, a lovely 

 species, introduced from New Granada. The flowers are large, per- 

 fectly flat, the sepals and petals white, with purple blotch at the 

 base, and the labellum white, with yellow blotch at the base. There 

 is a pure white variety, known as O. Rocdi album, and it is really 

 exceedingly beautiful. This is not yet " in commerce," that is 

 to say, it has not yet been offered in the trade catalogues. Most of 

 the nurserymen have it, and there are several fine examples of it in 

 Mr. Day's magnificent collection at Tottenham. 0. vexillarium, 

 sent out last year, gains in popularity, and commands about double 

 the price at which it was first offered, the minimum price now being 

 five guineas. It is certainly one of the finest orchids we have ; the 

 flowers are very large, the labellum being quite three inches across, 

 and are produced iu spikes of five or six each, and sometimes as 

 many as three spikes are produced from one pseudo-bulb ; the 

 flowers are of a pleasing shade of rose-lilac, and are wonderfully at- 

 tractive. O. Warsceiciczi is similar to the latter in growth, but the 

 flowers, wiuch are rather smaller, are of a creamy colour, with a
