Turs remarkably distinct Odontoglossum, which Prof, Reichenbach characterised as “an unusually stately plant,” has 
been the cause of creating some interest in the orchidaceous world. Unfortunately but few plants are in cultivation, and 
we are aware that more or less erroneous impressions prevail as to what this species really is. Many believe it to be the 
well-known O, lave, which has been in our midst nearly fifty years. A glance at our plate will at once refute the 
incorrectness of this idea, and at the same time illustrate the beauty and individuality of O. Schréderianum. There may, 
however, be some excuse for confounding this species with O. lave, as the formation of the flowers is somewhat similar ; 
but any one who knows the two plants cannot fail to be struck with the great difference in their colour. Besides, 
attention may be called to the fact that O. Schréderianum never produces such large and distinct pseudo-bulbs as O. 
lave, this latter species being easily recognised by its strong, compressed pseudo-bulbs, which are from three to five 
inches long, and assume a deep mellow brown colour as they become mature. 
O. Schréderianum is new to cultivation, having been first imported ‘by us in 1881 from Central America through 
our collectors. In May of the following year a plant flowered for the first time in this country in the collection of Baron 
Schroder, to whom it was dedicated by Prof. Reichenbach. Ata meeting of the Royal Horticultural Society in January, 
1885, Baron Schréder’s plant made its debut before the horticultural public, and was awarded a first-class certificate by 
the orchid committee. : 
The culture of this Odontoglossum is simple. It is best grown in well-drained pots, in a compost of fibrous peat 
and sphagnum, and should be placed near the glass, so as to obtain as much light as possible, without, however, 
subjecting the plants to the direct rays of the sun. In summer the Odontoglossum house will be found to suit its 
requirements admirably, and in winter it will be found to enjoy a temperature similar to that maintained in the cool end 
of the Cattleya house. Being a free-growing plant and liking a humid atmosphere, plenty of water may be given in the 
spring and summer months, after which the supply must be gradually decreased to enable the pseudo-bulbs to ripen 
properly. The approach of winter is the signal for as little water as possible, and is also indicative of the plants requiring 
rest for some weeks until they begin to push forth new growths under the genial influence of spring.
