FIELD MEETINGS, 1949 
Monday, July 18th. 
Coastal vegetation ivas again the object of this day’s excursion and 
the well-known Sea-lavender marsh at Holme-next-the-Sea was chosen 
for the morning’s work. En route a halt was made at the carstone 
quarry at Snettisham to see the masses of Verhascum pulverulentuin. 
This station is the headquarters for this plant, which is practically con- 
fined to Norfolk and Suffolk, and it is from this focal point that it may 
Ive traced in diminishing frequency to the south and east. 
On arrival at Holme the party studied the Limonietum which occu- 
pies a wide area. Some Salicornia species were noted around depres- 
sion pans on the salt-marsh, but these were not sufficiently mature for 
determination, although S. perennis was unmistakable and was confined 
to habitats with more shingle intermixed with mud. 
The grasses here were similar to those already seen at Wolferton 
but, in addition, Vulpia membranacea was noted in the sand-hills and 
also the salt-marsh variant of Agrostis stolonifera. 
Frankenia Inevis, Limonium vulgan-e, L. hinervoswni, and L. helli- 
difolium were among the more interesting plants of this station. From 
a small roadside osier plantation sterile material of two willows was 
taken, namely, S. calodendron and S. “fragilis" (? S. Basfordiana). 
After the usual picnic lunch Burnham Overy Staithe was the next 
stopping place. A long walk led to the marram-hills where the old- 
established dunes contrasted with the younger dunes of both Holme and 
Wolferton. Here several surprising species were found. They included 
Lathyris sylvestris in two large colonies reputed to be introductions. 
This plant appeared to be somewhat atypical and some peduncles bore 
as many as 15 flowers. Outliers, not yet flowering, of Gnaphalium luteo- 
album, from its well-known station whence it was recorded nearly a hun- 
dred years ago, were seen. Hypochoeris glabra was fairly common and 
masses of Epipactis palustris were in flower in the damp slacks together 
with a few withered spikes of Ophrys apifera. 
After this somewhat strenuous day members were ready for an early 
tea at the Moorings Hotel. Later, by kind permission of the Earl of 
T.eicester, the party was allowed to drive through Holkham Park, 
where the many specimen trees and avenues of evergreen oaks were ad- 
mired. Nearing King’s Lynn a halt was made at Vincent Hills, West 
Newton, where Mr Sandwith found a plant new to the vice-county 
in Althaea hirsuta growing in a field of lucerne. In the small aban- 
doned gravel-pit, surrounded by arable land, which is slowly reverting 
to heath, many unusual plants were noted, including the glabrous variety 
of Sisymbrium- officinale - Silene Cucuhalus, “a form with no reticula- 
tions to the calyx and petal-scales almost absent ” (Dr Young); Silene 
anglicn Galium erectum ; fruiting Hynscyamus niger; Salvia pratensis, 
well past flowering; and more plants of Apera interrupta. 
In the evening members were given a short but instructive lecture 
on grasses by Mr Hubbard, who used fieshly-gathered material to illus- 
trate varieties and diseased forms.
