Occasional Notes. 127 
The lip is quite novel in its shape for the labiata group. It is pandu- 
rate emarginate, rather broader in the front than at the base. If you 
like to see its outline well represented, take Botanical Register, 1847, 
plate 42,Cattleya bulbosa. This outline makes me record it as a new 
species, not one of the endless varieties of Cattleya labiata sensu ampli- 
sissimo. The column is singularly small, but it may have lost a good 
deal by being dried. 
And now the colours. The flower is of a fine purple-lilac. The 
whole anterior part of the lip is of the darkest, warmest purple. You 
might nearly compare this part to the end of the tail of a heathcock. 
The side wings of the superior part are purple, the centre light 
yellow. 
I think dried flowers and plants will give evidence of the accuracy of 
my description. It would be superfluous to lose many words in recom- 
mendation of this unexpected novelty. I will only say that I regard it a 
very good fortune to inscribe such a plant to such an orchidist as is Sir 
Trevor, and that I think the Cattleya Lawrenceana will rank, when 
established, under the finest Orchids imported by Mr. F. Sander. 
G. H. Rchb. f. [This, as we believe, quite new Cattleya was discovered 
on Roraima, the mountain in British Guiana recently ascended for the 
first time by our correspondent, Mr. im Thurn, and was sent home by 
Mr. Siedel. The flower is so well dried, and the bulbs are so healthy, 
that good materials exist for a woodcut, which we hope to issue 
very shortly. — Ed. of G. Chronicle.'] 
Next is the brief note attached to a pair of admirable 
wood-cuts of this orchid published in the paper. We 
regret much that we cannot here reproduce these illus- 
trations, 
We give in fig. 68 as accurate an appearance of the bulbs and leaves, 
and in fig. 69 the aftual size and form, and such indications of the 
superb colouring as is possible in a woodcut, of this fine introduction 
from the hitherto unexplored region, Roraima, in British Guiana, the 
full description of the flower, foliage, and bulbs having been given in 
our last number, p. 338. A large consignment of this splendid new 
species will be sold on the 26th instant, by order of Mr. F. Sander, the 
enterprising importer, by Mr. Stevens, at his rooms in King Street, 
Covent Garden, W.C. 
Lastly, here is the trade advertisement of the sale of
