Amonc the several large importations of Odontoglossums which we have received at various times there are always a 
certain number which when they flower appear to belong to what are known as natural hybrids—a group of Orchids 
which of late years has increased to a considerable extent. The plant which forms the subject of our illustration made 
its appearance a year or two ago in this manner, and when in flower, was submitted to the late Prof. Reichenbach, 
who gave it the name it bears, which has not hitherto been published. Odontoglossum hebraicum aspersum differs 
slightly from O. hebraicum, figured and described in the first volume of this work. It is characterised by its free 
growth and rather lax racemes of golden yellow flowers, beautifully blotched with rich purple-brown. It requires to be 
grown with O. crispum, and may receive the same treatment in every respect as that species. 
The mention of natural hybrids among Odontoglossums leads us to speak of artificial ones. The former are 
now very numerous, but it is a very curious fact that as yet no true seedling Odontoglossum has been flowered in 
cultivation, although Mons. Bleu, of Paris, has succeeded in raising and flowering a nearly allied plant under the 
name of Miltoniopsis Bleui, a cross between Miltonia vexillaria and M. Roezlii. A few years hence, however, we may 
expect to hear a great deal about true hybrid Odontoglots, for such there are in existence ; although, singularly enough, 
they are to be found, as far as we know, only in two establishments of the Rothschild family. At Tring Park, the seat of 
Lord Rothschild, a tiny Odontoglossum baby is thriving under the care of Mr. Hill; and at Armainvilliers, France, an 
estate belonging to Baron Edmund de Rothschild, quantities of true Odontoglossum hybrids exist: these have been 
raised by the orchid grower, Mons. Jacob, whose success in this branch of horticulture appears to be truly astonishing. 
Among Mons. Jacob’s hybrids is one between O. Rossii and O. Cervantesii, the characters of both of which are distinctly 
visible in the bulbs and leaves. An extraordinary cross has also been obtained between O. crispum (Alexandree) and O. 
luteo-purpureum, and the plants, which were raised in 1884, are now very large for their age, and are nearly sure to 
bloom next year. It is to be hoped that the flowers of these two hybrids, when they do appear, will be of such beauty 
in form and colour as to amply repay the attention which has been bestowed upon them, for there is nothing so 
disheartening to the hybridist as to find that he has been for years treating seedlings with the greatest care, which at 
length turn out miserable failures. We heartily wish Mons. Jacob and the superintendent, Mons. Leroy, every success 
in their undertaking, and congratulate them on being the pioneers in raising seedling Odontoglots, and on having 
attained results which have hitherto been considered almost impossible.
