FIELD MEETINGS, 1951 
Watson explained the routes which would be followed on the succeeding 
days and the main features of the places we would visit. Later in the 
evening Dr. Hora showed a number of colour slides of fungi. 
On Saturday morning the party was met at Sham Hill, below 
llemenham Lodge, v.-c. 22, Berks., by Miss K. H. Macaulay, who knows 
this area exceptionally well. The botanical treasure of the hill was 
Tetragonolobus (Lotus) maritimus (L.) Roth, known here for some years 
and found in comparative abundance. The only other addition to a 
normal chalk downland flora was Lotus tenuis Willd. A pleasant walk by 
the riverside at Henley Reach brought us to a small ditch with Myrio- 
phylluvi verticillatum L., Hottonia palustris L., Pedicularis palustris 
L., Hydrocharis Morsus-raaae L., Orchis praetermissa Druce and Tri- 
glochin palustris L. 
In the afternoon a visit was made to Bix Bottom, v.-c. 23, Oxford. 
This proved to be a good piece of beech woodland with Epipactis lepto- 
chila (Godf.) Godf. in some quantity. Dr. Young demonstrated its 
characters from the living plants. The wood also produced E. Eelle- 
borine (L.) Crantz, Monotropa Rypopitys L. and Lactuca muralis (L.) 
Gaertn. In scrubland at Maiden’s Grove above Bix Bottom we found 
Hypericum montanum L., Herminium Monorchis (L.) R. Br. and Paris 
quadrifolia L. on an old wall ; Ceterach officinarum DC. and Asplenium 
liuta-muraria L., and in neighbouring arable fields Iberis amura L. and 
Linaria repens (L.) Mill. Some members, detached from the rest on the 
way to tea at Nettlebed, saw CoeJoglossum viride (L.) Hartm. and an 
unusual form of Epipactis purpurata Sm. by the golf course at Nuffield, 
v.-c. 23. A visit was made in the evening to Bush Wood, near Nettle- 
bed, v.-c. 23, to see a fine show of Pyrola minor L. A number of mem- 
bers met again in the late evening at the Botany Department to discuss 
the day’s work. 
Sunday was spent entirely in v.-c. 22, Berks. A short visit w'as first 
made to a pond on Wakefield Common. This has a most interesting . 
flora including Hypericum Elodes L., Padiola Linoides Roth, Hydro- 
cotyle vulgaris L., Littorella uni flora (L.) Aschers., Sparganium simplex 
Huds. and Scirpus fl,uitans L. The greater part of the morning was 
spent on Silchester Common where, apart from the normal heathland 
flora, great interest was found in the flora of a small hillside bog, the 
neighbourhood of which added Genista anglica L., Cnscuta epithymum 
(L.) L., Pedicularis sylvatica L., Narthecium, ossifrnguin (L.) Huds., 
Orchis ericetorum. (E. E. Linton) E. S. Marshall, Carex laevigata Sm. 
and Equisetum sylvaticum, L. A short distance away was a marsh with 
a contrasting flora which included Panunculus hederaceus L., Peplis 
Portula L. and Veronica srutelhita L. var. villosa Sebum. 
In the early afternoon our attention was draAvn by Dr. Steel to the 
unusual flora of the verges of the runways of Crookham aerodrome. It 
was sui-prising to see chalkhill species growing close to heath species 
which had colonised the waste spaces beyond the verge. Of particular 
interest were Ononis Natrix L., LAnwm bienne Mill, and Stachys recta
