AMONGST the unarranged Lichens in the Hookerian Herbarium at Kew, is a small 
collection of Lichens from the Island of Saint Helena, gathered by Dr. W. Burchell in 
the year 1809, which I have been requested by Dr. Hooker to examine and name. 
Though not numerous, they are highly interesting and instructive, as well from their 
insular locality itself, as more especially from their approximate similarity to the 
* Lichenes Amazonici et Andini,” of Mr. Richard Spruce (see Linn. Trans. vol. xxv. 
p. 433 et seq.). 
I am informed that Dr. Burchell took great pains in their collection, from which I 
should conclude that he gathered every thing he saw, so as to render his collection as 
complete and comprehensive as circumstances permitted. From the condition of the 
specimens, they would appear to have been collected in haste within a circumscribed 
time; and many of them are not in a good state, sterile and broken. 
Subsequently Mr. J. C. Melliss, who has resided on the island for many years, 
forwarded to me for examination a collection which he had also made. "This contains 
many similar to those of Dr. Burchell's gatherings, and adds several others. I have 
indicated the collectors by initials, B. and J. C. M. We may conclude that we have now 
a fair knowledge of the lichen-flora of the island, though. no doubt the rocks, if well 
searched, would yield many additions; and this labour Mr. Melliss undertakes to 
accomplish on his return to St. Helena. The whole of both collections are deposited 
at Kew. E
