Odontoglossum X Troyanofskyanum. Hybridum novum apud naturam productum, floribus amplis pulcherrime luteo, 
albo et purpureo rubro maculatis. Sepalis oblongo-lanceolatis acuminatis ; petalis latioribus, oblongis, crispulis, obtusis ; 
labello obovato-oblongo, apiculato, crispo-denticulato, base subcordato, albo, ante lamellas cristae luteas transverse 
purpureo maculato. 
Odontoglossum X Troyanofskyanum L, LIND., supra. 
ew Orchids are a greater puzzle to the botanist than this group of 
4) hybrid Odontoglossum, of wich a certain number of forms have already 
#| been introduced and appear from time to time in the gardens. It 
Bae already been frequently tried to establish their filiation; it is even done 
sometimes with such mathematical precision, that we are rather disconcerted, but 
this very precision may lead to some mistakes. 
It may be easily understood that these plants have given rise to endless 
appreciations and comments, as most of them are very beautiful; on the other 
hand these comments may be made for some time to come yet, the difficulties of 
hybridization, or rather the raising of the seedlings, being so great in the 
Odontoglossum genus. 
Although hypotheses of this kind seem to be somewhat vain and uncertain 
— new discoveries having frequently upset foregoing theories — we think that 
we can without any fear ascribe the new form we new figure, to the crossing of 
O. Pescatorei with O. triumphans, or perhaps with O. praenitens. 
It is certainly difficult in such cases to determine the influence of either 
parent; we fancy, however, that we find the trace of O. Pescatorei in the ample 
form of the sepals and petals, in the white coloration which covers the central 
part down to the base, and in the form of the upper part of the lip; similitude 
to O. triumphans in the yellow coloration and red blotches of the segments, 
inthe general form of the lip (only rather modified towards the base), in the crest, 
and red blotch which is on the front part. The form of the lip and crest are 
the most distinctive features to be consulted in such a case; and we found our 
opinion on these elements of appreciation, finding no species more likely to be 
right to explain the origin of O. x Troyanofskyanum, than those above mentioned. 
It ought to be remarked that O. Pescatorei and O. triumphans are already 
the authors of O. x excellens; but although O. x excellens is fairly distinct from 
the form we are speaking of, it will be easily admitted that there is no incompa-
