A CENTURY OF CHANGE ALEC BULL STEVENS H E N S L O W was a scientist, Professor of Geology and Botany, the man who taught Darwin and encouraged him to join the 'Beagle', beloved Rector of Hitcham from 1837 until his death, founder of clubs, benefit societies, allotment schemes and many more, organiser of parish outings to places of interest, such as Cambridge or the Great Exhibition. More than this, he taught the village children Botany and left a list of plants of his adopted village covering nearly 25 years. In 1858, at the annual Horticultural Show, the Herbarium prize went to Maria Gosling for 171 complete herbarium specimens which were allowed for at one penny per sheet. The rules then followed for the 1859 competition, amongst which we find, 'to identify specimens, candidates should consult the School Herbarium. Failing this the Rector should be consulted'. Elsewhere it is recorded that a curate in the parish, after the death of Henslow, was flabbergasted when a very small girl came to him clutching a plant, and asked if it was a monocotyledon or a dicotyledon. JOHN
The present author's knowledge of the flora of Hitcham is confined mainly to the period 1944-1960, although he has made occasional visits since. Consulting Henslow's list, one immediately becomes aware of vast changes which have taken place in the intervening hundred years, a brief discussion of which is necessary before considering the list itself. Woodland With the exception of two remote fragments, the present woods are not at all species rieh, and are probably of no great antiquity. Henslow knew an exceptionally rieh woodland flora covering a fairly wide ränge of soil acidity, as at that time there were two considerable tracts of woodland: Hitcham Wood, which comprised some 102 acres, was cleared and turned into farm land about 1860, and Eastwood of 100 acres on loamier soil, which remained until after 1850. Grassland It was customary for grassland to remain unploughed for very long periods of time, and either grazed all summer, or from midsummer, after a hayerop had been taken. Thus a good sward of native plants became established which could remain undisturbed for centuries. In addition, Hitcham is a water shed, with the streams and ditches to north and south, flowing in
221 opposite directions, and many of the pastures had springs and tiny streams issuing from the clay, giving added botanical interest, much of which has since been lost by drainage and the plough. Little grassland is to be found in the vilage today, most is artificial, and none unfertilized. However, a few old pastures did survive until the 1950s or thereabouts, even remaining unfertilized. A few fragments of grasslandfloramay still exist in remote corners of some of the miles of grassy lanes, if they have not been churned up by tractors, or overgrown with neglect. A CENTURY OF CHANGE
Ponds
A number of aquatics have disappeared, due to infilling, fertilizer and herbicide pollution. Arable weeds
Species disappearance had begun even before herbicides made their mark, due to the improved Standards for the cleaning of seed com which had already eliminated such plants as Com Cockle and Pheasant's Eye, both of which appear in Henslow's list. Even such a plant as Vipers Bugloss may well have been brought in with seed from a light land part of the County. More recently the spray has replaced the horse hoe, and many more plants have disappeared or become rare, such as Com Crowfoot, always called 'Joy' round Hitcham. Also almost gone are the 'stock in trade' plants of the local herbalist, which included Henbane, Thorn Apple and Borage. The second named is of interest as it appeared in 1947, when an old cottage garden site, grassland forfiftyyears or more, was broken up and Borage still occurred in one spot every year between 1944 and 1960, and may still do so. For the benefit of this account, varieties on Henslow's list, which have since been accepted as fĂźll species have been upgraded accordingly. Included here for example, Lamium hybridum. This gives a list totalling 406 species which Henslow accepted for the vilage. One or two of these have names which lead to confusion. Under genus Scirpus he included Lake Clubrush and no specific epithet. Did he mean Scirpus lacustris, the Bullrush so called, or the Wood Clubrush, Scirpus sylvaticus which still occurred until recently by streams a few miles away? The 1944-1960 list included 395 species, but thefigureis of little value, as a number of new species have come in, a number of casuals have been recorded, and a number of plants of garden origin have become naturalized.

It is possible that some of these may have persisted until 1944, but most at least must be extinct by now. Conclusion Taking the most conservative figure, it is evident from the above that something like sixty native species have disappeared from the village in the 100 years. Their places have been taken, in part, by new arrivals, or plants able to survive the polluted margins of an arable monoculture which has replaced the balanced environment and its native plants, which Henslow knew.
