288 NOTES ON THE BOTANY 
the courses of quartz stones that may be seen on the moun- 
tain sides ; while Usnea melaxantha carpets the surface of 
these huge blocks, with its fronds varied of yellow, fawn and

M. d’Urville increases the number of Falkland Island spe- 
cies to two hundred and seventeen, of which ninety-seven 
belong to Cryptogamia. 
In 1841, Mr. Wright returned from a mercantile voyage to 
the Falkland Islands, where he very laudably employed his 
leisure time, during the summer months, in making a beauti- 
ful collection, which was presented to me ;* among them are 
some species that had not been previously found on the 
Islands ; and still more recently, a few specimens, gathered 
there by Lieut. Robinson, and communicated to me by the 
Admiralty, afforded a Hamadryas, a very fine Draba and a 
Gleichenia, which appear to have been overlooked by all 
former collectors. _ 
After these and other researches, it is hardly to be expected 
that much was left for the botanists of the “ Erebus and Ter- 
ror” to discover ; especially, seeing that their stay was almost 
wholly in the winter months. Yet, notwithstanding these 
disadvantages, the number of species of flowering plants, 
when the last intelligence came away, on the return of the 
expedition from Cape Horn, amounted to one hundred and 
seven, gathered by one individual. Of Cryptogamia, as may 
be supposed, there is a much greater proportion, and many 
of them are extremely beautiful ; and copious notes and draw- 
ings were made of both, which cannot fail to be of grea 
value. 
The “ Erebus and Terror" came to anchor in Berkeley 
Sound, on the 5th of April, 1842, the commencement of winter. 
The purser went ashore and returned after nightfall, but was 
entreated to bring on board a specimen of some vegetable 
production of the country. He grappled in the dark, and
