Jury, 1917.) THE ORCHID REVIEW. 149 
Burford, produced a scape, bearing one normal flower and one having three 
fertile anthers, and a lip almost exactly like the one on Mr. Bull’s plant in 
shape. Lastly a plant of the same variety in the establishment of Messrs. 
Linden, Brussels, produced a spike of flowers identical with Uropedium 
in every respect but colour, this being of the delicate light tint of the 
variety in question (Lindenia, vii. t. 321). Both the latter were received 
alive, eliminating all possibility of mistake, and are now preserved at Kew. 
It is now clear that Uropedium Lindenii originated as a sport or 
mutation from some form of Cypripedium caudatum, and has become 
diffused from its original birth-place, probably on account of its coming 
true from seed, as some other abnormal forms are known to do. It must 
thus be regarded as a permanent mutation—not a distinct genus in the 
ordinary sense—just as Paxtonia rosea is a mutation of Spathoglottis 
plicata, and Dendrobium normale a mutation of D. fimbriatum. We do 
not know whether any attempt has been made to raise Uropedium 
Lindenii true from seed. Three hybrids were raised from it by Messrs. 
Veitch, C. macrochilum, C. Penelaus, and C. giganteum (the other parents 
being respectively C. Roezlii, C. calurum, and C. grande), but in each case 
the hybrid had a normal lip, which may be regarded as due to the stronger 
influence of ‘the normal parent. It would be interesting to try the effect of 
self-fertilising the Uropedium, and ‘thus throw light on what is probably 
occurring in nature. It may be added that the Uropedium was the pollen 
parent of the two first hybrids mentioned, but the seed-bearer in the third. 
It now remains to indicate the geographical distribution and differences 
of the forms of C. caudatum already mentioned. The original C. caudatum 
was collected by Ruiz & Pavon, it is believed in the Huanuco district of 
Peru, where, probably, W. Lobb afterwards met with it, while Davis 
collected it at Muna. C. caudatum Sandere, as far as we can see, is 
identical, and Mr. F. Sander writes that this was collected by Forget in 
the extreme south of Peru, but he cannot get at Forget’s letters at present. 
It is a big form, and the different plants are uniform in colour (as described 
at page 137). The richly-coloured Central American var. Warscewiczii 
was originally collected by Warscewicz, at Chiriqui, Costa Rica, where 
Lehmann subsequently collected it, his specimens being localised as Rio 
Caldera, Chiriqui. This form extends further north, having also been 
collected in British Honduras by Skinner, and in Guatemala by Turckheim, 
whose specimens ate localised as Pansamala, Dept. Alta Verapaz, 3800 it. 
The smaller, light-coloured var. Wallisii is a native of Ecuador, where it 
has since been collected by Lehmann, at Zamona, on the eastern Andes of 
Loxa, at 500 to 1300 metres. Lastly, we have the abnormal variety 
Uropedium (Uropedium Lindenii) whose characters and distribution have 
been pointed out above.
