THE ORCHID REVIEW. 167 
HYBRID ODONTOGLOSSUMS. 
(Continued from vol. vt. p. 187). 
One of the difficulties that one has to contend with in identifying the 
various natural hybrids which appear is the absence of information as to 
the exact range of the different species, and the consequent difficulty of 
finding out which of them grow together. This applies not so much to the 
older hybrids, which are now pretty well known and easily recognised, as to 
_the novelties which appear from time to time. The one called O. X 
harvengtense may be taken as an example. It was described as a supposed 
natural hybrid between O. crispum and O. sceptrum, which presupposes 
the fact that the two grow together, though no evidence was adduced in 
confirmation of this, and the facts known pointed the other way. I referred 
it to O. xX excellens (O. R., ii., p. 201), but the point has since been 
disputed. A plant exhibited by Messrs. Charlesworth & Co., at 
Manchester, as O. X harvengtense, appeared to be only a distinct variety 
of O. triumphans, but the curious thing is that it is said to have come in 
an importation of O. crispum. Several times recently I have seen plants 
of O. triumphans said to have come out of crispum importations, and have 
thought that the plants have been accidentally mixed, for they have 
hitherto come from different districts, but the question arises whether the 
two grow anywhere intermixed. A little group staged at Manchester by 
Messrs. Charlesworth, contained O. crispum, triumphans, harvengtense, 
and what I take to be a form of O. Pescatorei, and these are said to have 
come together tied to sticks in the usual way they are imported. But does 
this necessarily prove that they grew, and were collected, together ? 
One thing, however, is certain, and that is that we do not yet know all 
about the distribution of O. crispum in a wild state. For many years it 
has been imported from Pacho and neighbouring districts, where it has 
been found intermixed with O. gloriosum, luteopurpureum, and 
Lindleyanum, and out of these importations examples of the hybrids, O. 
x Andersonianum, xX Wilckeanum, X Coradinei, X mulus, and X 
acutissimum have continually appeared. Then O. ‘Hunnewellianum was 
discovered in some region, we believe, north of Bogota, and, still later, O. 
crispum was found in this very district, and together with it the charming 
little hybrid O. x Adrianz. It flowered unexpectedly among importations 
of O. crispum from a new district, and among them were examples of O. 
Hunnewellianum itself, which removed any remaining doubt about the 
origin of O. X Adrianz, which is precisely intermediate between them. 
It is evident that O. crispum and O. Hunnewellianum hybridise together 
very freely, for the forms of O. x Adriane are already numerous, and as 
variable as these hybrids usually are. It includes forms with both light
