That this is the long lost Epidendrum guttatum of Linnaeus, 

 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 limdum 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 Forhesii 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 structure 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
