to germinate. If S . squalidus be not in the neighbourhood of the 
East Cornwall plant, my supposition that it is a variety of S. vulgari s 
will be strengthened. Mr. Carroll, I believe, sfill thinks it a hybrid 
between S. vulgaris and S. squalidus. — J T. Boswell. Tregantle 
is about five or six miles from Plymouth, in which neighbourhood 
S. squalidus is unknown. — T. It. A. B. 
Senecio viscosus, Linn. “Numerous examples came up this year 
on the gravelly margin of the Metropolitan Railway Station, at High 
Street, Kensington, July, August, 1875. The plant seems to have 
originated from the coal-dust, the trains coaling here. It might be 
worth any Welsh botanist’s while, within reach of this spot, to see 
whether the species grows there.” — J. L. Warren. 
Bidens “ Tigbrtda.” “ Surrey side of Thames at Putney, October, 
1875.” — J.. L. Warren. This form of Bidens I have formerly 
received from Mr. Warren, gathered on the banks of the Willesden 
Canal, Middlesex. I at that time thought it might be a hybrid between 
B. cernua and B. tripartita, but I now believe it to be a luxuriant form 
of B. tripartita , into the ordinary state of which it seems to pass 
imperceptibly. It is distinguishable by the leaves being undivided — 
that is, not having lateral lobes which give them their tripartite form. 
The anthodes have a broader pericline and more numerous florets, 
and the fruit has frequently three or even four awns, although the 
lateral ones are always much longer than the inner and outer. The 
root is precisely similar to that of ordinary B. tripartita, having the 
root-fibres irregularly disposed, not produced from the lower nodes of 
the stem as in B. cernua, from which it differs also in the stalked 
leaves, with much broader laminae, and the erect or suberect an- 
thodes. — J. T. Boswell. 
Crepis biennis, Linn. “ By roadsides near Eldon, a few miles 
from Bishop’s Auckland, 1875.” — John Robson. “Roadsides and 
hedgebanks, Bishop’s Auckland, Durham, July, 1875. Occurs on the 
magnesian limestone in the vicinity of Bishop’s Auckland, and has not 
been previously recorded for Northumberland or Durham. In July, 
1875, I found it growing freely along both sides of an unfrequented 
lane and in the hedges of the adjoining fields, and if not indigenous 
it is thoroughly well established.” — J. B. Sohxter. The occurrence 
of this species in the locality has been recently noticed in the report 
of the “ Botanical Locality Record Club ” for 1875. It may be only a 
recent introduction to the neighbourhood of Bishop’s Auckland, for it 
has spread at a wonderfully rapid rate in the vicinity of Plymouth, 
and bids fair to become a very common weed. — T. R. A. B. 
Crepis tectorum , Linn. “ I have the pleasure of forwarding forty 
specimens. It still keeps its ground. If introduced with farm seeds
