anum as a new variety, remarking :—‘ This appeared among numerous 
specimens of Odontoglossum maculatum. It has lemon coloured sepals 
and petals, all spotted with brown, and a whitish-yellow lip, spotted with 
some reddish-brown, which has a very light hue of sepia. The callus and 
bracts, and shape of the lip, prove it to be O. maculatum, not O. cordatum, 
though the sepals and petals are rather long. I hada fine infloresence, with 
six quite fresh large flowers, kindly sent me by M. L. De Smet-Duvivier, 
Mont St. Amand-les-Gand.” It was afterwards figured in Lindenia, as O. 
Duvivierianum, with the remark that it appeared to be “‘a natural hybrid 
between O. maculatum and O. nebulosum.” This remark is quite borne 
out by the figure, and I therefore consider it a form of O. x vexabile. The 
following are the references to descriptions and a figure :—

ODONTOGLOssuM X WARNERIANUM dates from a still earlier period, 
having been described by Reichenbach in 1864, though asa new species, and 
although its hybrid origin was afterwards suspected, its parentage has been 
a matter of uncertainty down to the present time. Its author originally 
described it as a new species, from the collection of R. Warner, Esq., of 
Chelmsford, allied to O. maxillare, Lindl.,with flowers as large as those of O. 
nebulosum, Lindl., but shortly afterwards he remarked :—“ This pretty plant 
might be called a connecting link between Odontoglossum nebulosum, Lind]. 
and O. Rossii, Lindl. It has the slender, narrow pseudobulbs of the last, and 
the broad petals of the first.” Mr. Warner, in figuring it, added “ the plant is 
supposed to be a native of Mexico, but nothing positive is known as to its 
history or introduction. It flowered, first, we believe, in our collection 
several years ago.” Mr. Bateman, who, of course, regarded it as a 
species, of the affinity stated, was unable to add anything to the above 
information except that it had ‘also flowered with the late Mr. Cauty, of 
Liverpool, who kindly sent me the specimens from which the figure was 
prepared, but these were smaller and less rich in their colouring than those 
of Mr. Warner.” Lastly, Messrs. Veitch, who reduced it to a variety of O. 
Rossii, remarked that it was ‘a very distinct form, probably of hybrid 
origin.” 
The plant is clearly allied to O. Rossii. though quite distinct, but I 
cannot trace the resemblance to O. nebulosum. ‘That species has much 
larger pseudobulbs, each bearing two much longer leaves, and the resem- 
blances in the flower, with its curved claw to the lip, do not seem to be 
more marked. There is a closer resemblance to O. Cervantesii, especially
