BOTANICAL EXCHANGE CLUB. 
end-leaflets round (not obovatej with a decided cusp, panicle with 
more numerous and stronger prickles, and denser, more numerous 
flowers with shorter pedicels. I know of no special name for this, 
but it is a well-marked form that comes in between mucronulatus, 
villicaulis, and fuscoater. The true mucronulatus, which Dr. 
Boswell sends this year from the neighbourhood of Aberdour, 
in Fife, we do not get anywhere in the neighbourhood of London. 
Pi: villicaulis. Mr. Bagnall sends a plant from New Park, Mid- 
dleton, Warwickshire, which Bloxam named R. heteroclitus, Wirtgen. 
This seems to me a slight variety of R. villicaulis, and another 
plant from Mr. Bagnall from the same locality named adscitus by 
Bloxam to be typical villicaulis, as we understand it in England. 
R. ramosus, Blox. Minworth, Warwick, J. Bagnall ; and 
Bircham, Egg Buckland, South Devon, T. E. A. Bkiggs. This 
seems to me a well-marked bramble, allied to rhamnifolius. I have 
never met with it about London, or in the north of England. 
ii. Hijstrix. Wormley Wood, Broxbourne, Herts, Dr. Ceespigny. 
R. pi/ramidalis. Easton Bishop, Hereford, Kev. A. Ley. 
fi. diversifulius, Lindl. A form with ascending sepals from 
hedges at Heslington, near York, G. Webstek. 
Pi. corijlifolius var. R. degener, Muller. Under this name, for 
which I am indebted to Genevier, I have distributed a few speci- 
mens, from hedges at Kew, of a bramble that comes in between 
Batfouriamis and corylifulius var. intermedius. It has angular 
barren stems, copious large prickles on the rachis of its panicle, and 
ascending fruit- sepals. 
Lythrum hyssopifuliitm. This I gathered last year in small 
quantity on the Surrey side of the Thames above Kew Bridge. 
Helosciadiuin nodijiorum var. ochreatum, DC. (Sium hybridum, 
Merat.) Barnes Common, Surrey, G. Nicholson. This is a 
dwarf forjn of nodifiorum with small obtuse leaflets, one to three 
lanceolate bracts, and flower-umbels on peduncles one-quarter to 
one-half of an inch long. From H. repens, which is very rare in 
Britain, with which it is sometimes confounded, it differs by its 
assurgent flowering stems and shorter peduncles. 
Sedum Forsterianum. Limestone rocks, Downton, Hereford, 
Eev. A. Ley. 
Valerianella eriocarpa. A good supply from the neighbourhood 
of Penzance from Messrs. Cunnack and Waterfall. 
Galium Bakeri. Myton Wood, near Leamington, Warwick, H. 
Bromwich. 
Carduus setosus. Borders of fields near Finchley Koad Station, 
Middlesex, Dr. Crespigny. 
C. pycnocepludus, L. Limestone cliff under the Hoe, Plymouth, 
South Devon, T. E. A. Briggs. This is what I understand as the 
true pycnocejdialus, as defined by those authors (such as Grenier 
and Godron), who separate it as a species from our common 
English C. tenuiflorus. Curt. 
Hieracium “ riyidum." From the river-banks. Bishop Auckland, 
Durham, J. P. Soutter. I should call crocatum and his “ Lf. 
yothicum- ” from the same station tridenlatum, of which latter Mr.
