Many thousands of plants flowering on all the semi-roughs; absent on fairways and greens, rare-occ. in roughs, R Payne & G Crompton, 18-24 July, 1975.
Size of population and notes: There is obviously a large population of this species on the golf course. It is present on all areas of rough and semi-rough surveyed (see above) and was flowering and seeding. It is quite adaptable to different mowing regimfrom completely prostrate to an upright bushy plant c.30 cm in height. Mr Murphy said that its widespread occurrence was the result of a Cambridge University don casting the seeds around when he played golf! A very local leaf-beetle Longitarsus parvulus is associated with the plant. Sarah Lambert, 19.8.1986.

Position and grid ref. corrected: [Error in JC Faulkner's position due to 'County' signs being where boundary swerves from centre of road to west side of road, and not where boundary branches eastwards at 510.461.] G Crompton, 20.6.1978.

West side. Rsv has had soil dumped on it during road works in 1987. 9 clumps between 'Soft verge' sign (at north end), and 50 paces south, roughly opposite where trees end on top of bank on opposite side of road (south end).The verge is now only 4 paces wide between the tarmac and the small bank. This 'new' verge has abundant Cirsium vulgare near the road-side and Arrhenatherum elatius along the middle of it. There is Desmazeria rigida on bare chalk patches. Associated species with the 9 clumps of Linum are: Briza med, Helic pra, Linum cat, Ononis rep, Polyg vul, Poter san, Scabi col. Col. print looking NNE at west side, with a stick at 1st of 9 clumps looking towards 'Soft verge' sign. G Crompton, 20.6.1988.

East side: c.50 clumps, large patch of Hippo com at N. end, CP looking S. G Crompton, 20.6.1978.
East side: Large numbers of scattered clumps over 70 paces. Assoc species with Linum: Briza med, Helic pub, Trise fla, Oroba ela (in bud); on flat verge: Carex fla, Linum cat, Polyg vul (freq.) and Hippocrepis comosa. Col. print looking SSW with very large patch of Linum by stick. No Helia cha or Thymus pra seen, otherwise rest of Faulkner's species listed on his Pop. map are present. G Crompton, Pop. map, 20.6.1988.
Plants growing on both sides of the road. If at one time there were only plants on the west side, and the eastern group is a sub-colony, it is curious that the eastern plants are so much more numerous–even though, presumably owing to less dry conditions, the western ones are on average larger than the main groups on the east side.
East side: The site extends over an area with a flat verge of about 5 yds depth, behind which there is a 10 ft chalky bank topped by a low hedge. Further to the north, where the bank has ceased, the verge widens and continues, without undue overgrowth, at the level of the fields; but there are no Linum there. On the site we can distinguish three subgroups: Subgroup I–on the flat verge, extending over the north and central sections of the main site; Subgroup 2–On the chalk bank, extending over the south and central sections of the main site; Subgroup 3–an isolated, concentrated group to the north of the main site, at the edge of the field where the bank has ceased. The lay-out is like this: Pop. map:
Subgroup I: Four plants/clumps, scattered, about 30 fl. showing. Nearby ground plants include Silene vulgaris, Polygala vulgaris, Lotus cor., Linum cat. Many small Crataegus bushes, looking likely to take over; also some Rhamnus cat. (female bush in fl.).
Subgroup II: 28 plants/clumps, scattered at north and south of their range, a good number concentrated near the middle of it. About 150 fl. showing. Bank mostly bare, chalk often visible; a few Crataegus and Rhamnus encroaching.
Subgroup III: Five mostly large to very large clumps; about 375 fl. showing, over 200 in one clump. Sepals look to me paler and somewhat more pointed than in I and 2; any chance of hybridisation with L. usitatissimum from the field?
West side: A little further to the south than the plants on the East side. Verge narrower (3-4 yds), no bank; high hedge of Crataegus, rose, ash etc. Verge grass and undergrowth much more lush than on the east side; ground plants coarser–including Heracleum, ox-eye daisy, Reseda, field poppy, Silene latifolia. Competitive environment, but our guys look cheerful enough. Six clumps, two of which large. About 84 fl. showing. As on the east side, there is a quite extensive area of open broad verge stretching to the north, but without any sign of L. perenne on it. P.Daunt, 3.6.1990.
43 clumps on east side, and 6 on the west side, MJY Foley, 11.6.1991.

16+ 12+ seedlings in 15 x 12 ft. area very sparsely colonised, grasses virtually absent. No mature plants found above chalk exposure on 'original' verge grassland so origin of this colony not clear. East side of A.11, in cutting c.500 yds south of Brent Ditch on steep chalk exposure made c.1960, '513.471', Pop. map, JS Faulkner, 25.7.1975.
Position and grid ref corrected: 512.466. West side of road: scattered fl. plants almost to end of pines at N. end; 2 large clumps on bank. CP looking N. East side: main colony of c.20 clumps fl on ± bare chalk bank (a few plants towards top of bank), scattered plants on verge. CP looking N, and close up of colony on banks, G Crompton, 20.6.1978.
' Northern Station' (512.466). Whole area is a cutting, with a verge of about 3 yds either side and high banks (c.20 ft) with plenty of chalk showing. A much gloomier picture than at southern site.
Western Side: No Linum perenne. On the verge end bank some rose, privet, wayfaring-tree, sycamore. Bank largely smothered in low bramble; Linum cath abundant in gaps, little else. Toward north, two posts (southern one flimsy, northern one stout) half-way up bank, about 60 yds from each other. Could be protected area markers but there is no perceptible difference in the flora between them.
Eastern Side: At north end of cutting, bank covered in bramble. On verge, sallow, sycamore, rose, privet; some on bank too. Only Linum perenne on this station near south end of cutting, about one third of way up the bank, on open chalk. Three plants, four fl. showing, over area of 5 yds. P. Daunt, 3.6.1990.
34 clumps on east side, (plus many non-flowering), but none found on the west side, 512.464, MJY Foley, 11.6.1991.

Signal Hill Plantation, Permission to visit the site was obtained by 'phoning Babraham Farms. 'Chris' who gave me permission seemed very interested, and volunteered information so that one felt the site was being well looked after. I reached the site by walking the farm track on the SW side of the plantation; on reaching the S. end the contours drop away, and there is an area of grassland some 50 m wide before the arable field is reached, most of the L. perenne plants are concentrated in the SE corner of this grassland in an area some 90m long by 40m wide. It was difficult to estimate the number of individual plants but in an area 10 x 10m over 100 plants were counted, perhaps 8 to 10% of these had white flowers. There was no sign of scrub invasion in this area. On the North side of track between the track and the wood there were 3 large plants and some scrub. Estimate 1,000+ plants of L. perenne, some 8-10% white. K Tucker, between 29.5 and 7.6.1990.
Linum in full flower–wide range of 'colours' with 27 clumps pure white and some very pale blue going to deep blue.

(G Crompton and Farm Manager, Chris de Jonge tried to persuade the Swiss Co's Estate Manager, Peter Burnett, not to plant up a small corner of site with additional pretty flowers, and he said he would instead now do so round their pumping station.)
