THE ORCHID REVIEW. 325 
HYBRID ODONTOGLOSSUMS. 
(Continued from Vol. I1., page 330.) 
Our last paper concluded the hybrids from the Ocaiia district, and we may 
now consider those from the Andes of Ecuador, where several species 
occur, and where, as at Bogota and Ocatia, some of them grow intermixed. 
The four Ecuadorean species from which hybrids have been derived are 
O. cristatum, Lindl., O. cirrhosum, Lindl., O. Hallii, Lindl., and O. 
Kegeljani, E. Morr. (O. polyxanthum, Rchb. f.), and at least eight different 
forms have been described, which apparently belong to five different crosses, 
as shown in the following diagram :—

The three species first named have all been collected in the Loxa district. 
O. cirrhosum has rather an extensive range on the western Cordillera, for, 
according to Lehmann, it ranges between 4° S. latitude and 2.15° N., from 
Loxa northwards. O. Hallii extends from about Loxa up to Quito, close 
to the Equator, and possibly further north, at about 8000 feet altitude. 
The distribution of O. cristatum is very imperfectly known, but Hartweg 
collected it in the Loxa district, and it also grows with O. Kegeljani 
(polyxanthum), some distance further north, and has even been reported 
from as far north as Popayan, so that its range is probably not inconsider- 
able. The habitat of O. Kegeljani has also not been very exactly indicated, 
as far as I have discovered, but for the present purpose it may be roughly 
indicated as somewhere between Loxa and Quito, as we have now evidence 
that in some locality it grows in company with O. Hallii. It is probably 
less widely diffused than that species. We may now consider the hybrids 
individually :— 
13. ODONTOGLOSSUM X CIRRHOSO-CRISTATUM.—This hybrid originally 
appeared in the collection of W. Marshall, Esq., of Enfield, and was 
described and figured by Reichenbach in 1870 as O. X hinnus. It was 
compared with O. luteo-purpureum and O. gloriosum, which the author, 
probably unaware that it came from Ecuador, apparently considered might 
be the parents. A year later a plant flowered in the collection of J. Day, 
Esq., when Reichenbach pointed out the resemblance in the lip to O. 
cristatum. A fine inflorescence sent to Kew by Baron Schroder in June, 
1891, shows an unmistakable combination of characters derived from O. 
cirrhosum and O. cristatum, the former being well represented in the shape
