ONcIDIUM FORBESIO-DASYTYLE.—In 1843 Oncidium Gardneri was de- 
scribed, and although universally considered as a species, I have little 
doubt it is a natural hybrid derived from O. Forbesii and O. dasytyle, two 
very different species. Here again we note the curious fact that one of the 
species, namely, O. dasytyle, was not known until many years afterwards, 
being described for the first time in 1873. O.elegantissimum and O. Pollet- 
tianum were probably derived from the same parentage, and possibly O, 
prestans also. 
Oncidium x Gardneri was originally described by Lindley, in 1843, as a 
fine species allied to O. crispum and Forbesii, distinctly separated by the 
peculiar form and tuberculation of the lip, and by the very small wings of 
the column. It was collected on the Organ Mountains, in December, 1836, 
by Gardner, who states that he only found a single plant of it." 
In 1846 Messrs. Rollisson, of Tooting, received from M. Pinel, a 
botanist and collector of plants residing in Brazil, an Oncidium under the 
name of O. flabelliferum, which soon afterwards flowered, and was figured 
- in Paxton’s Magazine of Botany ; though it is evidently only a form of O. x 
Gardneri, as Reichenbach pointed out in 1877, just after the true plant was 
introduced by Mr. B, S. Williams. 
Another plant, which also appears to be a form of O. x Gardneri, 
appeared in the collection of M. Massange de Louvrex, at Baillonyille, in 
1877, and was figured as O. pretextum, though it is not Reichenbach’s 
Plant of that name. Messrs. Veitch remark of O. x Gardneri that “‘its 
appearance in British gardens at long intervals and in limited quantity 
would imply that it is a rare plant in its native country,” which is quite explic- 
able on the theory now put forward.. 
Oncidium x elegantissimum appeared with Messrs. James Veitch and- 
Sons, of Chelsea, in 1876, and was described by Reichenbach as a new 
Species. It was compared with O. curtum and O. Gardneri, being especially 
near the latter, with which it agrees in the shape of the lip and in having 
the calli of the base with blackish purple borders. It is probably only a 
variety of the same, in which the crest is rather nearer O. Forbesii. =~ 
Oncidium x prastans appeared in 1880, in the establishment of Messrs, 
James Veitch and Sons, of Chelsea, where it was found among a lot of O.

* Curiously enough, Lindley named the original specimen in the Hookerian Herbarium, 
“0. Forbesii,” though a sketch of it, with three dried flowers from the same specimen, in 
his own Herbarium, he labelled “O. Gardneri.” He appears never to have known it 
Properly, for three flowers of O. crispum, labelled ‘ O. Forbesii,” are attached to the same 
sheet ; while O. flabelliferum, which is a form of O. x Gardneri, he placed among the 
“Species insufficiently nove” Reichenbach also states that Lindley sent to him flowers of 
0. crispum labelled, “ O. Gardneri.” -
