HYBRID ODONTOGLOSSUMS. 
(Continued from page 144.) 
ONE other matter deserves careful consideration, namely, whether some 
of these natural hybrids may not be of secondary origin, and even 
of complex parentage. Respecting this point, Messrs. Veitch remark: 
“The agency by which these hybrids and polymorphisms have been 
produced, has been in operation for ages past, and it cannot but have 
happened that a large number of these forms, both of those that are 
known and of those hereafter to be brought to light, are not the immediate 
offspring of two recognised species or more primitive type, but are 
descended from their mixed progeny, further complicated by an occasional 
cross with one or other of themselves.” This point may be left for the 
present, but from a variety of considerations, some of which have already 
been touched upon, I do not think such cases are as common as might at 
first be supposed. 
The importance of a knowledge of the geographical distribution of 
the species of Odontoglossum will at once be apparent in this connection, 
but, unfortunately, information of this kind is not always easy to obtain. 
This point may be left for the present, and it may be that even the 
hybrids themselves may furnish information on the subject. 
We may now proceed to enumerate the natural hybrids which have 
hitherto appeared, commencing with some of the best known ones, and 
atranging each under the joint names of its two parents, in accordance with 
the botanical rule for naming hybrids. In this way various forms having 
the same origin can be kept together—in fact, it is the only natural method 
of arranging them. 
ODONTOGLOSSUM X GLORIOSO-cRISPUM.—The habitat of Odontoglossum 
crispum is on the western spurs of the eastern Cordillera of New Granada, 
from about 345° to 5°50° N., or from about ninety miles north to 
ninety miles south of the city of Bogota, and at an altitude of about 7,500 
to 8,800 feet above sea-level. Here, in certain localities, it is found in 
company with O. gloriosum, O. luteopurpureum, and O. Lindleyanum, and 
it is a remarkable fact that it crosses freely with each of them. With the 
former alone we are at present concerned. 
_ As already pointed out, Odontoglossum x Andersonianum, “jeccelee in 
1868, was the first natural hybrid known. It appeared in the previous 
year, in a batch of O. crispum sent by Blunt to Messrs. Hugh Low and Co-, 
of Clapton, whence it passed into the collection of the late James Dawson, 
Esq., of Meadow Ba ank, near Glasgow, and was named in compliment to. his 
gardener, Mr. James Anderson. Reichenbach described it as one of those 
doubtful Odontoglots so troublesome to the Orchidist, and remarked that at
