3 o6 THE ORCHID REVIEW. 



and figured by Dr. Klinge in the following year, under the name of C. 

 bicolor var. olocheilos {Act. Hort. Petrop., xvii., p. 135, t. 1, fig. 6). It is 

 described as differing from typical C. bicolor in having the perianth 

 segments " olivaceo-flavo-brunneis," more or less spotted with purple, the 

 petals spathulate, obtuse, and undulate, and the lip nearly pandurate, 

 somewhat convex, with the front lobe dilated, roundish, and retuse or 

 emarginate. Messrs. Low state that their plants came in a separate 

 importation, and from the neighbourhood of Rio de Janeiro, but the exact 

 locality they do not know. About fifty or sixty plants are in flower, 

 differing somewhat among themselves, but all showing the remarkable 

 dilated front lobe of the lip, a character also seen in plants flowering at 

 Kew and Glasnevin, and quite different from anything seen in the old 

 C. bicolor. It is thus clear that we have a distinct local type to deal with, 

 and not a mere individual variation. As to the idea of the plant being 

 a natural hybrid between C. bicolor and C. guttata (it is even suggested 

 that the latter was the seed parent), there are two facts which tell strongly 

 against it. First, the total absence of side lobes from the lip, and second, 

 the fact that the plants came home separately as an entire importation. 

 The forms at present seen by me vary from ij to if inches in the breadth 

 of the lip, and from coppery brown to dusky olive brown in the colour 

 of the sepals and petals, and both with and without spots. The colour 

 of the lip is almost uniformly deep rose-pink, sometimes with a white spot 

 on the centre of the disc. There is a certain resemblance to C. Leopoldi 

 in the shape, colour, and spotting of the petals, but it extends no further, 

 and the habit of the plant, and absence of side lobes from the lip, prove 

 it to be a near ally of C. bicolor, though I do not regard it as a simple 

 variety of this old species, but rather as a distinct local race or subspecies. 

 The ample dilated front lobe of the lip gives it a very distinct appearance, 

 and it is far more showy than the old type. We hope to see its history 

 completely cleared up, and there are several other Brazilian Cattleyas of 

 which further information would be acceptable. Our hybridists might also 

 let us know what a real hybrid between C. bicolor and C. Leopoldi is like. 



Since the above was written, Mr. I'Anson has taken the photograph 

 which is here produced, showing two forms of C. Grossii (figs. 32, 33)) 

 side by side with one of C. bicolor (fig. 31), which illustrates in a graphic 

 way the differences between them. Besides the broader lip of C. Grossii, 

 it will be seen that the petals are distinctly convex and reflexed at the 

 apex, with stronger undulations than in C. bicolor, and the remarks apply 

 to some extent also to the sepals. The two figures of C. Grossii give 

 some idea of the amount of variation in shape, but not in colour, and the 

 amount of spotting on the petals.
