I. Butler The nomenclature followed for the flowering plants is that of Clapham, Tutin & Warburg in the "Flora of the British Isles" except for two species from Dandy's "Check List of British Vascular Plants". As the botanists tend to go further afield, the radius of the area covered is now extended from the usual ten to a rough twenty miles from Reading. The Recorder thanks all who have made this Report possible, In spite of the phenomenal fine weather which broke so many records during 1959 and of the many observations carried out by botanists, from the first leaf buds of Arum maculatum L. found on January 1st to 23 species seen in bloom near Span Hill, Henley Road, at the end of the year, there were few botanical records of outstanding interest. Of the 596 plants, including grasses, that she actually noted in flower during the year, Mrs. & M. Simmonds remarks that 559 were Berkshire species or could be found in the neighbouring counties (Hants, Oxon, Bucks) within ten miles of Reading, while 95 were observed within the Borough of Reading. Minor observations by Mrs. Simmonds were the absence of flowers on Fagus sylvatica L. (Beech) (a non-flowering year seems to occur very few years) and of fruits on Fraxinus excelsior L, (Ash) and Acer campestre L. (Maple), though many trees were examined, Professor Hawkins has commented on the extreme abundance of fruit on Taxus baccata L. (Yew) this autum. After last year's success, 1959 proved rather disappointing for orchids, To follow up the record of Miss HE, Harris in 1958 of Crocus purpureus Weston (Purple Crocus) growing in the Inkpen district of Berkshire, Dr. Erith and the Recorder visited the pasture and saw the crocus growing in great profusion and with a wide range of colour from dark purple to white. The form alluded to by Druce (1894) was also noted, "the immer perianth segments beautifully veined with darker lines, the dark primary veins and a large number of secondary ones crossing one another obliquely from the margin", Professor T. Harris (Reading University) has sent the following obser- vations on Potamogeton nodosus Poir. (= P. drucei Fryer). "IT have searched the Loddon from Basingstoke to Stratfield Saye Park without finding a trace. Then a few hundred yards below Stanford End Mill (just below Stratfield Saye Park) it begins as a dense mass, so dense that it is hard to get a boat through it. Below that it occurs all the way to Wargrave, but only in abundance in water less than about 3 ft. deep and flowing fairly quickly. This perhaps suggests that the species reached the Loddon somewhere below Stanford Hnd at some time and has been very slowly creeping upwards, but that it spreads downwards with ease from broken-off bits of rhizome." Last year Mr, 4. Price introduced some members to Chara vulgaris (Common Stonewort) growing in a Burghfield gravel pit. This year he has found, after a lapse of nearly two years, Nitella translucens, another -—~ 1] = member of the family Characeae, It was growing in the pond near the "Three Firs", Burghfield, probably the same pond where Druce in 1887 saw it "filling it to the exclusion of other aquatic vegetation," Further Members!

Simmonds has sent the following observations, "In a copse below Avenue liouse, Sindlesham, two plants were | seen on March lst, each bearing a flower, and several plants without leaves, : All these plants were very near the river's edge, and one speculates whether the bulbs have been brought down by flood-water from Moor Copse a few miles ; upstream. It will be interesting to see whether G. nivalis will establish itself in this wood if it remains unmolested." Coeloglossum viride (L.) x Orchis fuchsii Druce, This hybrid, found last year on the Moulsford Downs, was considered to be in danger from grazing cows, so was transplanted to a safer spot by li. D.E. Bradley. Gymnadenia conopsea (L.) (Fragrant Orchid). Growing in quantity again on the Moulsford Downs, but being grazed by cows (D.E. Bradley). Orchis simia Lam. (Monkey Orchid), Although this orchid is still holding its own, it is apparently being interfered with in some way. A film of its nine fine blooms was taken by ir. Boggart (Bournemouth) , but Dr. Erith reported that a few days later only six flowers were found and there were obvious signs that the plants had been disturbed. When iirs. Simmonds and Mrs. E. R. Blackwell visited the slope on May 20th, only two very poor specimens were seen, even after a careful search. QO, morio L. (Green-winged Orchid), Abundant in a paddock near Newbury; in a field at Russell's Water. Miss Cobb reports that both these localities were being grazed by horses, and wonders if there is any connection between the decrease in the orchid and the decrease in the horse population, O. ustuleta (Burnt-stick Orchid). The Downs near Ashton Upthorpe were visited again this year, and although buds were seen early by D. EH. Bradley, lirs. Simmonds and Mrs, Paul failed to find any flowers on June 10th, Aceras anthropophorum (L.) S.F. Gray (Man Orchid). The slope on which it has been recorded since 1945 has now been completely ravaged by pigs, and no plents were seen there this year (Mrs. Simmonds). denne, trisulca L, (Ivy Duckweed) md L. minor (L) (Duckweed).

The plant had grown to a height of 8 ft., and presumably originated from waste bird-seed (Irs. Simmonds). Amaranthus retroflexus L. (Green Pigwood), Another alien plant occurring as a casual. Sent to the Museum from Winnersh (irs. Simmonds); waste ground, Pangbourne (J. Hodgson). Datura stramonium L. (Thorn—apple). Dr. Perrin, Director of the Maps scheme of the Botanical Society, has mentioned the widespread growth of D. stramoniun, probably due to the long dry summer. Such is the power of the press, supported by the Ministry of Agriculture and the police, that this season it has become Public Enemy Noel, and Reading, where it has made several appearances, has not been immune from ae scare. = Lh - The Recorder's Report for Entomology 2230 ed By B.
