especially O. labiata, to a variety of which (C. Mossiz) 
Reichenbach compares OC. iricolor in habit of growth, say- 
ing, “it looks like a dwarf CO. Mossizx.” C. labiata is 
found from New Grenada and Guiana in lat. 10° north, 
to Rio de Janeiro in lat. 233° south. The variety Mossiz, 
long considered a species, is, however, confined to the 
Cordillera of Venezuela. A glance at the figure of it 
given in Plate 3669 shows pseudobulbs very like those of 
C. iricolor, but quite different flowers. In some respects 
the leaf and flowers of C. iricolor resembles those of Laelia 
grandis (see Plate 5558), but besides the difference of 
colour and of the pseudobulbs, the four pollinia of C. 
iricolor are absolutely distinctive of its genus. Mr. Rolfe 
with much reason suggests the Peruvian Amazons as being 
its native country, relying on its affinity with C. Rea, 
Lindl., of that region. 
It is singular that in the colouring of the lip there is 
some discrepancy between the descriptions of Reichenbach 
and Veitch, and these again with the figure here given. 
Thus Reichenbach says of the lip, ‘it presents a zigzag 
band of dark orange from the top of one side lobe to the 
other. There are numerous violet lines both before the 
orange zigzag line and behind it, and from thence to the 
base of the lip. The small column is whitish, and has a 
large violet spot on its front.” Veitch’s Manual says, 
‘lateral lobes milk-white, with a few purple streaks, a 
bright purple spot, and an orange blotch near the anterior 
edge of each; middle lobe white, with a transverse orange- 
pam band at the base, on each side of which is a purple 
otch. 
I am indebted to the Baron Sir John H. W. von Schroeder 
for the opportunity of figuring for the first time Cattleya 
iricolor, that celebrated orchidophilist being the possessor 
of, in so far as is known, the only existing specimen of it 
in the Old World ; the drawing was made in May, 1892, — 
ae ae exhaling at the time a very strong sweet odour.
