332 THE ORCHID REVIEW. 
luteopurpureum. The flowers are blotched with a dark brown on yellow 
ground. Almost immediately afterwards it appeared successively with the 
late Mr. Day, at Tottenham, M. J. Linden, of Brussels, and Messrs. James 
Veitch and Sons, of Chelsea. 
Odontoglossum x cuspidatum was described very soon afterwards, from 
dried specimens collected by Roezl. The flowers are a little smaller than 
in O. x mulus, and approach rather nearer to O. gloriosum. The inflorescence 
is panicled, and the flowers yellow heavily blotched with chestnut-brown, 
The lip is rather narrower and more acuminate than in O. x mulus, and the 
ground colour very light yellow. It was afterwards met with by Messrs. 
Coradine and Chesterton, when collecting for Messrs. James Veitch and 
Sons, of Chelsea. Though described as a species, it is evidently a hybrid 
between the two species now under consideration. 
Odontoglossum x histrionicum appeared in 1882, with Mr. William 
Bull, of Chelsea, and was compared with a light-coloured O. x mulus, the 
ground colour being sulphur-yellow. It is evidently derived from the same 
parentage. 
Odontoglossum x tentaculatum appeared in the collection of Baron 
Schréder, of The Dell, Egham. Reichenbach described it as intermediate 
between O. x ligulare and O. x rubens, and remarked that it would be 0. 
x Kalbreyeri, but for its tentacular bristles and column-wings. It is, how- 
ever, clearly descended from O. luteopurpureum and O. gloriosum, and thus 
a variety of the present hybrid. 
Certain varieties of the preceding types have also been described. For 
example, Odontoglossam x mulus Holfordianum is a large flowered form, 
with fewer blotches on the sepals and petals, which appeared in the colle: 
tion of R. S. Holford, Esq., of Weston Birt, Tetbury, Gloucestershire 
Bockett’s variety is a handsome form, with the blotches on the pe 
harrower than usual, which appeared in the collection of John S- Bockett, 
Esq., of The Firs, Muswell Hill. O. x cuspidatum xanthoglossum apes"! 
with Mr. B. S. Williams, of Upper Holloway, and chiefly differs in ve 
a yellow lip.t ©. x histrionicum bellum appeared with Messrs. Heath é 
Sons, of Cheltenham, in 1883, and is said to have all the tints of a lighter 
shade, especially the yellow ground. f 
This hybrid is evidently both common and variable, though the th 
colour is not so great as in the preceding ones. The inflorescence is gener : 
branched, as in both parents. The ground colour is generally deep yel . a 
as in QO. luteopurpureum, though sometimes as light as in O. gloss?

and is said to grow in an isolated spot, where no oth

It has no right to the name cuspidatum.
