THE ORCHID REVIEW. 139 
HYBRID ODONTOGLOSSUMS. 
(Continued from vol. i, page 334-) 
Our last paper concluded the hybrids from the Bogota district, and we now 
come to those from the region about Ocaiia, one of the great Odontoglossum 
centres. Here grow O. nobile (Pescatorei), O. triumphans, O. tripudians, 
O. blandum, and O. crocidipterum, together with O. luteopurpureum, 7; 
gloriosum, and O. Lindleyanum, which are found also around Bogota. 
The following diagram indicates the hybrids which are certainly known 
from this district. It serves, however, to emphasise the fact that O. x 
glorioso-luteopurpureum and O. x Lindleyano-luteopurpureum may also 
occur here.

Besides these there are at least two others, which are believed to have 
come from this region, whose parentage remains doubtful, and these will be 
considered in their turn. 
Odontoglossum nobile, Rchb. f., or O. Pescatorei, as it is usually called— 
though the former name has priority by four years, Reichenbach having 
originally described it in 1849, from dried specimens collected by Funck and 
Schlim two years previously—is a native of the north-west branches of the 
Eastern Cordillera, of New Granada, in the neighbourhood of Ocafia, from 
about 6,000 to 9,000 feet elevation, and is said to be spread over an area of 
about ninety square miles. Other species have been found growing upon 
the same trees with it; for example, O. triumphans, O. Lindleyanum, O. 
luteopurpureum, O. crocidipterum, and O. tripudians, and with the three 
former, at least, it readily hybridises, as we shall now see. 
O. X LUTEOPURPUREO-NOBILE.—This hybrid originally appeared in 1880, 
but still seems to be very rare, and consequently less polymorphic than 
those previously considered. It is quite intermediate between the two 
parent species, both in shape and colour. The four following plants all 
appear to be forms of this hybrid, the second and third, however, I only 
know from description. 
Odontoglossum x Horsmanii was collected at Ocafia by Mr. Fred 
Horsman, for the New Plant and Bulb Company, Colchester, and flowered 
in 1880. Reichenbach, in describing it, remarked, ‘‘ There can be scarcely 
a doubt left that the present plant is a mule between O. Pescatorei and
