(4) THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 1 44 
Report. The 1901 and 1902 Reports occupied 66 pages. Un- 
fortunately in 1903 the Report was paged from i to 34, and 
that for 1904 I to 40, as at that time I was unaware Mr. C. 
Bailey contemplated preparing a separate Index for his series. 
In this Report, therefore, two sets of page numbers are used, the 
one in brackets running from i to 52 ; the other starting at 141, 
so that the members can, if they choose, insert the consecutive 
numbers from the 1902 Report, numbering the first page of 
the 1903 Report p. 67 and so on, the last page of the 1904 
Report being 140. Then the Reports for the years 1901 — 10 
will form the second volume. 
Among the chief items of Botanical interest of the year 1904 
are the following : — 
Koeleria Britannica. Under this name Dr. Domin has 
named a rather widely-spread form, which he calls a sub-species 
of K. gracilis, Pers. He diagnoses it as follows : — ‘ Pro more 
laxiuscule caespitosa rhizomatibus saepe prorepentibus vel tenuibus 
vaginis siccis pallidis longe involucratis, culmi humilioribus vel 
altioribus totisxpubescentibus (mox praecipue sub panicula, mani- 
feste villosulis, mox tantum brevissime tenuiter pubcrulis), foliis 
brevioribus vel longioribus semper angustis planis usque setaceo- 
convolutis^molliter hirsutis nunquam rigidis, vaginis dense molliter 
pubescentibus culmum laxe ambientibus vel subpatentibus suprema 
pro more minus dense et breviter vestita subinflata, paniculax 
lobata, spiculis bifloris rarissime trifloris c. 4 mm. longis pube- 
scentibus puberulisve raro fere glabris, glumis saepius acutis (nec 
acuminatis), glumellis baud raro aristulatis, flosculis e glumellis 
parum exsedentibus,’ It ranges from the Orkneys to Kent, and 
from Cornwall to the Isle of Man. 
Among the other Koelerias Dr. Domin has also recognised 
K, GLAUCA, DC. as the sub-species K. arenaria, Dumort., which 
occurs from East Sutherland to Dorset. Of this a new hybrid, 
K, supra-arenaria, Domin, is described. It is the plant which 
was distributed through the Club by Mr. J. E. Griffith in 1888 
under the name K. cristata, var. arenaria, Lej., from Trefadog, 
Anglesey, and from the beach near Llanfaglan coast, near Bangor, 
in 1892, as K. cristata, f. humilis, as corrected by Prof. Hackel.
