Erigeron canadense^ L. Gloucester Docks, v.-c. 34, Sept 
1908. — F. L. Foord-Kelcey. 
Matricaria suaveolens, Buch. Abergavenny, Monmouth, Aug. 
1908, also at Crickhowell ; on the hillside, near Craig Lille, here 
evidently introduced with chicken food ; at Hay, by the river, 
Brecon. — G. Claridge Druce. Yes : this alien was sent to the 
Club in 1903, 1906, and 1907. Can we not be spared it in the 
future ? — H, J. R. The rule of the Club is that plants which 
are not ‘ desiderata ’ can be sent from counties for which they 
are unrecorded. — G. C. Druce. 
M. inodora L. var. discoidea Celak. St. Philip’s Marsh, 
Bristol (on a tipping), 26th June 1905. — J. W. White. 
Some Segregates of S. vulgaris, Linn. 
About the year 1891 I began to examine a striking radiate type 
of groundsel which is very abundant near Cardiff, and in January 
1894, Dr. C. T. Vachell sent a specimen to Kew, which Mr. 
Hemsley reported upon as follows : — “ I cannot make anything of 
this but vidgaris, b. radiatus” The occurrence, ten years later, of 
two distinct radiate forms in my own garden at Penarth, and of a 
very distinct dwarf form in the Cathays Park, Cardiff, induced me 
to submit all the local forms to a test which may be described 
briefly as that of experimental pedigree culture. 
The experimetits commenced in September 1905, and are still 
in progress. Already it ‘has become necessary to recognize the 
seven segregates contained in the set. 
These may be arranged, according to their affinities, in four 
groups: — (a) prcecox and genevensis : (b) erectus ; erectus, var. 
radiatus ; and latifolius : (c) multicaulis : and (d) lanuginosus. 
The last was kindly sent to me from Guernsey by Mr. Marquand, 
genevensis was collected at Montreux, and the remainder were found 
in or near Cardiff. 
Lajiuginosus is so distinct that it will probably have to be 
separated altogether from vulgaris: if identical with S. denticulatus, 
Nolt., which seems probable, it would of course retain the latter 
name, and take rank as an ordinary or primary species. The 
remaining segregates, with the exception of the radiate varieties, 
may conveniently be regarded as “ elementary species ” of the 
aggregate species, A. vulgaris, Linn. 
Hybrids of these seven types probably occur in every possible 
combination. The following have been obtained experimentally 
and sometimes in each of the two possible ways : — (i) prcecox X 
erectus, var. radiatus ; {2) erectus x erectus, var. radiatus ; and (3) 
multicaulis x erectus, var. radiatus.
