1 8 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
Rosa pseudo-rusticana, Crepin. Chetnole, Sherborne, Dorset, 
26 August 1903. — W. Moyle Rogers. 
Rosa pomifera Herrm. Undercliff near St. Margaret’s, Kent. 
One bush far away from houses, noticed by Mrs. Davy and myself 
in July 1903. ^ New to the Kentish flora. — G. Claridge Druce. 
Crataegus oxyacanthoides^ Thuill. Near Ashridge, Bucks, May 
1900. A distinct species, in my opinion. — G. Claridge Druce. 
Saxifraga hirsuta, Linn, ex horto Prestwich. Roots from 
Glen Curragh and the Gap of Dunloe, Co. Kerry. June 1903. — J. 
Cosmo Melvill. Correct, I think, though not extreme in leaf- 
characters. I should have been disposed to name it S. Gcum x 
umbrosa. — E. S. Marshall. 
Saxifraga Andrezvsii Haw. (S. Guthriana, Engler). Originally 
discovered by Mr. Andrews on rocks at head of Glen Curragh, 
Co. Kerry, but since sought in vain. Grown in garden at Prestwich 
for the last quarter of a century from specimens obtained from 
the Botanical Gardens at Cambridge, where the examples are 
labelled ‘ received from Mr. Andrews from Glen Curragh, Co. 
Kerry.’ My brother and sister visited the Irish habitat two or three 
years ago, and well searched the mountain at the head of the Glen, 
where Mr. Andrews recorded the species, but the only Saxifrages 
they noted were umbrosa and hirsuta. It has been by some con- 
sidered a hybrid between umbrosa and Aizoofi, the last not British, 
but I am not sure whether this has been proved. I have both these 
growing together, and have never noticed the least tendency to 
hybridise. It is true that the seeds [of Andrewsii\ are infertile ; 
and this lends some colour to the assumption of hybridity. Ic 
increases by barren shoots bearing rosettes very profusely, and 
is one of the handsomest of the Robertsonian group.— J. Cosmo 
Melvill. This has just the characters that one would expect 
to result from S. Aizoon (or one of its allies) hybridising with 
S. umbrosa. That such a plant was ever wild in Kerry is incredible. 
Most probably it arose from natural crossing in Mr. Andrews’ 
garden, and was erroneously supposed by him to have been brought 
from Glen Curragh. The only apparent alternative to suggest is 
wilful imposition. — E. S. Marshall. 
Epilobium parviflorum, Schreb. Near Alston, W. Lancs. (60). 
— J. A. Wheldon. a drawn-up apparently shade-grown E. parvi- 
florum, Schreb. — E. S. Marshall. 
Epilobium obscurum x parviflorum. Near Bamford, Derbs., 
3 August 1903. — W. R. Linton. Correct. — E. S. Marshall. 
Carum Bulbocastatium, Koch. Wilbury Hill, Herts., July 1903. 
In some quantity in arable fields, and sparingly on the turfy 
margins. — G. Claridge Druce.
