That this is the long lost Epidendrum guttatum of Linneus, 
a Jamaica plant, unknown to Swartz, who so carefully in- 
vestigated the Botany and especially the Orchidaceous plants 
of the island, I do not doubt. The name luridum ought 
therefore in strictness to be abolished ; but that of guttatum 
applies so generally to the whole genus, that there would be 
more inconvenience than advantage in the measure. 
It was imported from Jamaica by Messrs. Rollissons, to 
whom I am obliged for the specimen from which the figure 
has been taken. Certainly, O. Lanceanum and Forbesii alone 
excepted, this is the most beautiful plant of the genus yet in 
our gardens; the richness of its colours, the profusion of its 
flowers, and its stately growth, for it is from three to four 
feet high, would even make it doubtful whether it does not 
rival the former species, only it wants the aromatic odour. 
In structuré it differs nothing from O. luridum, so far as 
I can ascertain. 
It requires to be cultivated in the orchidaceous-house or 
moist stove, either suspended from the roof, or elevated above 
March, 1839. G
