This magnificent Orchid is a native of Costa Rica, and was 
flowered last September by Wentworth Buller, Esq., F.L.S., 
of Strete Raleigh, Exeter, who informs me that one spike 
bore no less than thirteen fragrant flowers, of the size and 
colour represented in our Plate. 
When figuring the original Brassia Lawrenciana, Dr. 
Lindley well remarked that “the species of this genus are 
difficult to distinguish from one another, especially those 
which have the lateral sepals much lengthened out.” The 
flowers of the original state are not half so large as those of 
our plants, the lateral sepals measuring barely three inches, 
whilst they are fully seven inches long in the var. longissima ; 
the colours, too, are considerably different, a deep orange- 
yellow, with few large, broad, purple blotches in the variety, 
but a pale golden-yellow, with more, much smaller, paler, 
redder bars in the original. In more important characters, 
however, the two plants agree so closely, that I have followed 
JANUARY Ist, 1869.
