NOTES ON THE BRITISH CHARACEJE FOR 1887-9.
By Henry and James Groves.
(Plate 296.)
Of the three years which have elapsed since the publication of
our last instalment of ' Notes,' 1887 and 1888 were comparatively
unproductive of additions to our knowledge of the British Chara
Flora. During 1889, on the other hand, one new species has been
added to our list, and we have received specimens representing
important extensions of the known distribution of several of the
rarer species.
In our 'Notes' for 1883 we gave a list of the 48 Watsonian
counties from which we had not seen specimens of any of the
species. This list is now reduced to 22, riz.:—Gloster E., Monmouth,
Denbigh, Flint, Ayr, Linlithgow, Aberdeen N., Banff,
Cantire, Ebudes ]M. & S., Cork S., TipperaryN., Kilkenny, Carlow,
Queen's Co., Wexford, Kildare, King's Co., Longford, Monaghan
and Tyrone. The most neglected districts at the present time
are:—1. That around the Bristol Channel and almost the whole of
Wales, Carnarvon and Anglesea being excepted. 2. A band across
the south of Scotland from Ayr to Berwick. 3. North Aberdeen
and Biinff, 4. The Islands from ]\Iull to Cantire. 5. A large tract of
the interior of Ireland reaching almost from tlie north to the south.
Through the kindness of ^Ir. F. J. Hanbmy, we have been
enabled to examine the specimens of British Charas in the herbarium
of the late Dr. Boswell, the most interesting result being the finding
of a specimen of Nitella mxicronata from Hants N. We take this
opportunity of thanking our correspondents for the specimens they
have sent us.
