328 THE ORCHID REVIEW. 
to me from description. It appeared in the establishment of Messrs. F 
Sander & Co. some years prior to 1883, but was not described until that 
year, when it re-appeared in the collection of E. Salt, Esq., of Shipley, near 
Leeds, and was described by Reichenbach under the name of Odontoglossum 
x chetostroma. It was imported with O. Hallii, and bore a raceme of 
sixteen flowers. It was described as near the last named, but with more 
stellate flowers, the sepals and petals being narrower, and densely covered 
with dark blotches, and the lip and column most resembling O. Hallii. 
Reichenbach asked—‘ Is it a mule between Hallii and cristatum ?” And 
judging by the description this seems highly probable, as it is clearly different 
from the two preceding hybrids. 
The following are the references :— 
Odontoglossum x cheetostroma, Rchb. f. in Gard. Chron., 1883, i., pp. 
562, 592. 
16. ODONTOGLOssSUM xX CRISTATO-KEGELJANI. — In 1878 a curious 
Odontoglossum appeared in the establishment of Mr. W. Bull, of Chelsea, 
which Reichenbach described under the name of O. x cristatellum, stating 
that it was probably a natural hybrid between O. cristatum and some species 
like triumphans or epidendroides. Then a plant appeared with Mr. Oscar 
Schneider, of Fallowfield, near Manchester, and another with Mr. Buchan, 
of Southampton, when Reichenbach spoke of it as one of the best marked 
and rarest of hybrids. Still later it appeared with Messrs. Hugh Low & Co., 
and in the collection of R. H. Measures, Esq., of Streatham, when 
Reichenbach again remarked on its rarity and compared it with O. 
luteopurpureum. Since then it has appeared in various other collections 
among importations of O. Kegeljani (polyxanthum), which is evidently one 
of the parents. In fact it shows an unmistakable combination of the 
characters of this species and O. cristatum, sometimes approaching more 
nearly to one parent, and sometimes to the other. O. triumphans and O. 
luteopurpureum do not grow in this district at all, and are clearly out of 
the question. 
In the same year in which Odontoglossum cristatellum appeared, a so- 
called species from Ecuador was described by Reichenbach under the 
name of O. Lehmanni, but four years later the author reduced it as a 
synonym of O. x cristatellum. :

hybrid :—
