1. The branching stem is only a trifling modification of 

 the ordinary habit of Cattleyas, whose rhizoma is the stem, 

 of which the pseudo-bulbs are the branches. 2. The furrowed 

 pseudo-bulbs exist equally in C. labiata. 3. Nothing can 

 well be more variable than the size of the sepals and petals, 

 and consequently of the flowers themselves in different indi- 

 viduals, and under different circumstances. Sir W. Hooker 

 describes the original C. Mossia) as being seven inches and a 

 half in diameter, from the tip of the upper sepal to the end 

 of the labellum ; from tip to tip of the two opposite petals 

 eight inches and a half, each petal being a little more than 

 four inches long, and two inches and a half broad ; twenty- 

 four inches in the circumference of the entire blossom ! 

 One such specimen I have seen, in the collection of Mrs. 

 Lawrence, and it is probable that similar cases will not be un- 

 common when the imported plants shall have recovered their 

 full health ; but up to the present time the greater part of 

 the specimens I have seen are not larger than the flowers in 

 the annexed plate, and are therefore less rather than larger 

 than C. labiata. 4. I do not find the petals more unguicu- 

 late in the one than in the other ; but they are broader and 

 more crisp in C. Mossicb than in its prototype. 5. To colour 

 alone of course no importance can be assigned. 



It is not merely in the case of C. Mossiae that the supposed 

 species of the genus require reconsideration. It is probable 

 that C. Harrisonii is a var. of C. Loddigesii; and C. inter- 

 media, is certainly nothing more than a state of C Forbesii, 

 with the yellow exchanged for white and purple.
