30 ON CAREX ERICETORUM AS A NATIVE OF BRITAIN. 
to England; I shall thus lose a very kind friend, who has been 
like a brother to me. I heard from Mr. Hewen that you had 
inquired if it were possible to ascend the mountain of Bimbia or 
Cameron. You will hear shortly that it is quite impossible, and 
only killing men to send them up there; this, however, was also 
told me before I went up Clarence Peak. It is, no doubt, very 
difficult, but it is possible; only too much must not be expected 
from the first trip. Much might be gained by a second ascent ; 
as would also, I think, be the case, if I could ascend the Peak 
here again, and remain there for some months during the dry 
season. To stop there in the wet season is quite impossible, and 
would be certain death.  .

On the Discovery of Carex ro m Poll,asa N ative of Britain.

of Botany in the University of Cambridge. 
[Read June 20, 1861.] 
SEVERAL months since my friend Mr. John Ball, F.L.S., sent to 
me a specimen of Carex, gathered by him on the Gogmagog Hills 
in Cambridgeshire in the year 1838, and upon a careful examina- 
tion of my Herbarium I found four specimens of the same plant, 
gathered at the same place on May 3, 1838, and probably in com- 
pany with Mr. Ball. This plant was supposed by Dr. Boott to 
be the C. ericetorum, Poll. On referring to my notes I was 
enabled to ascertain the places visited on the above-mentioned 
day, and have lately revisited them more than once. At length, 
on Mav 28, 1861, I was so fortunate as to rediscover a single 
rather large patch of the same Carex, growing on the grassy slope 
of the Roman road, locally called the Wool Strect, at about four 
miles and a half from Cambridge, and probably not far from the 
spot where it was gathered in 1838. 
As I have now no doubt of its being the C. ericetorum, and a 
true native of the country, I venture to announce it as an addi- 
tion to the British flora. This is no “split” from a recognized 
species, but a plant allowed by botanists to be a true species. At 
first sight it much resembles C. precox, and inhabiting similar 
ground, may have been overlooked in many places. To the prac- 
tised eye it has a. decidedly ditferent appearance when growing;
