greenish, with very numerous small light brown spots. The disc and crests of 
the lip are yellowish-white, and the acuminate apex brown; the column is also 
yellowish white. According to ReicHenBacu’s description it appears to be some- 
what variable in colour. 
It is very distinct from its allies in the character of the pseudobulbs, in fact 
these have such a different appearance that it was not at first recognised as 
an Odontoglossum at all, but when the flower-spikes appeared its affinity was 
apparent. These organs though ovoid in shape are very little compressed later- 
ally, and their colour green, marbled with dusky brown. Some of these pecularitus 
may be somewhat modified when the plant becomes established in cultivation. 
Its re-appearance is extremely interesting.

in its normal condition, has not been found. This fact, however difficult to under- 
stand, cannot explain away one of another kind, namely that on more than one 
occasion flowers having the essential characters of Uropedium have been borne 
on plants of the normal form. And equally conclusive is the evidence derived 
from a totaly different source, namely that the hybrids derived from crossing both 
Uropedium Lindeni and Selenipedium caudatum with S. longifolium and its varities 
are practically identical. 
There are three nearly parallel casis in other groups, to which attention 
may be called. The so-called genus Paxtonia, established by LinpLey, is now 
known to be a peloriate state of Spathoglottis plicata; Argyrorchis javanica bears 
the same relation to Macodes javanica, and Dendrobium normale to D. fimbriatum. 
Dendrobium normale, though it has escaped the somewhat questionable honour 
of being elevated to the rank of a separate genus, presents a somewhat analagous 
case to that of the Uropedium, for, so far as I can judge by the somewhat meagre 
published information, it is common in two or three localities in the Western 
Himalayas, where no D. fimbriatum grows, and, so far as I can ascertain, the 
relation of the two forms has not before been made out. In each case the 
adoption of the peloriate condition seems to have been beneficial, as that form 
has prevailed to the exclusion of the normal one, and become fixed or permanent. 
Do they come true from seed? We are here confronted with a very interesting 
problem which presents itself for solution.
