A very pretty species of Oncidium with buff-orange

SPRING-FLOWERING DENDROBIUMS. 



The spring-flowering Dendrobiums are extremely useful decorative plants, 

 and for some weeks past have been flowering in profusion in most Orchid 

 collections. The species are very numerous, and of late years there has 

 been a large accession of hybrids, so that there is a wealth of materials 

 to select from, and some of the former are not as commonly met with as 

 their merits deserve. One at least of the two figured on succeeding pages 

 comes under this category, namely, D. Devonianum, and the reason 

 probably is that it is often a difficult plant to grow satisfactorily. Mr. B. S. 

 Williams states that the great secret is to give it plenty of water when 

 growing, and always to bear in mind that the red spider is its desperate 

 enemy, often attacking the leaves. This pest should be diligently searched 

 for, and, if found, kept under by syringing the foliage every day, or even
