_ODONTOGLOSSUM Xx LINDLEYANO-TRIPUDIANS.—This is another very 
interesting Odontoglossum, which made its appearance in 1887, in the 
establishment of the New Bulb Company, Colchester, and was sent to 
Reichenbach by Dr. Alexander Wallace, who believed it to be a hybrid 
between O. Lindleyanum and O. tripudians. It was described under the 
name of O. x Staurastrum. It was compared to O. Lindleyanum with 
broader segments, light yellowish green in colour, blotched with brown: 
and the stalked lip with a three-lobed blade, sepia-brown in front of the 
crest, and some mauve stripes and spots between the low keels; the column 
nearly that of O. Lindleyanum, also the leaves, while the pseudobulbs 
were round, like those of O. tripudians. I have not seen the individual in 
question, but believe its parentage is correctly described. 
In May, 1889, a plant flowered with the Liverpool Horticultural 
Company, Garston, near Liverpool, which closely resembled a dark O. 
Lindleyanum in the shape and colour of the sepals and petals, though the 
colour of the lip, and details of the crest and column wings, all showed the 
same approach to OQ. tripudians, which clearly indicates its origin and 
parentage. 
In June, 1890, another form appeared in the collection of M. A. Van 
Imschoot, of Mont St. Amand, Gand, which I described as a natural hybrid 
with this parentage, under the name of O. x Imschootianum, completely 
overlooking its earlier name of O. x Staurastrum. It is lighter in colour 
than the preceding, though clearly a form of the same hybrid. 
In October, 1891, another form appeared in the establishment of Messrs. 
F. Sander and Co., St. Albans, in which the shape and colour of the lip, and 
the fimbriate column wings all have more of the character of O. tripudians, 
though the narrow sepals and petals and some other details all show the 
same unmistakable evidence of O. Lindleyanum, which was evidently the 
other parent. 
The following are references to the published descriptions of this 
hybrid :— 
Odontoglossum x Staurastrum, Rchb. f. in Gard. Chron., 1887, i. p. 313- 
O. X Imschootianum, Rolfe, /.c., 1891, ii. p. 758. 
There are two other Odontoglossums from the same region whose 
hybrid origin is almost beyond doubt, though, unfortunately, the same 
cannot be said respecting their parentage. These may now be considered. 
ODONTOGLOSSUM X MURRELLIANUM.—This originally appeared in the 
collection of W. Burnley Hume, Esq., at Winterton, Norfolk, in 1875, in 
a lot of imported O. Pescatorei, and was named after that gentleman’s 
gardener, Mr. Murrell. It was described by Reichenbach as a natural- 
hybrid between O. nobile (Pescatorei) and O. nevium. The influence of 
the former is undoubted, but the latter grows far away, in the Santa Martha
