THE BOTANY OF NOTTINGHAMSHIRE 69 



ustuluta, Stratiotes aloides, Scheuchzeria palustris, Carex digitata, Melica 

 nutans, Hordeum europaeum, Ceterach officinarum, Cystopteris fragilis 

 and three species of Lycopodium. Turning from this melancholy list of 

 probable extinctions it is a pleasure to note that a fair number of species 

 which have always been rare in the county still persist. Among these are 

 Myosiirus minimus. Ranunculus parviflorus, Aquilegia vulgaris, Hyperi- 

 cum montanum, Sagina nodosa. Geranium lucid um, Arabis glabra, Lotus 

 tenuis. Slum latifolium, Dipsacus pilosus. Inula squarrosa. Campanula 

 patula, Monotropa hypopitys, Samolus valerandi, Galeopsis dubia, 

 Littorella uniflora. Rumex maritimus, Ophrys apifera and O. muscifera. 

 Narcissus pseudo-narcissus, Convallaria majalis, Gagea lutea, Spaganium 

 minimum, Acorus calamus, Schoenus nigricans, Carex pseudo-cyperus, 

 Calamagrostis epigeios, Apera spica-venti, etc. Moreover a number of 

 truly native species which were unknown to, or not distinguished by, the 

 earlier Nottinghamshire botanists have been discovered in recent years: 

 e.g. Ranunculus lingua (discovered along with Lathy rus palustris at Misson 

 by Mrs. Sandwith and her son Mr. N. Y. Sandwith), R. lenormandi and 

 several Batrachian Ranunculi, Corydalis claviculata, Viola stagnina and 

 several other species, Polygala dubia and P. serpyllacea, Stellaria neglecta, 

 Ulex gallii, Medicago denticulata, Lathyrus palustris, Agrimonia odorata, 

 Callitriche stagnalis, C. obtusangula and C. truncata, Epilobium adnatum, 

 E. angustifolium (now an excessively abundant and pernicious weed), 

 Carum segetum, Selinum carvi folia, Arctium majus and A. minus, 

 Arnoseris minima. Gentiana baltica, Melampyrum cristatum, Mentha 

 alopecuroides and other species. Polygonum laxiflorum, Rumex limosus, 

 Platanthera chlorantha. Orchis praetermissa, Polygonatum multiftorum, 

 Potamogeton coloratus, P. falcatus, P. cooperi, P. friesii and P. interruptus, 

 Scirpus fluitans, S. tabernaemontani and 5. maritimus, Carex canescens, 

 C. binervis and C. fulva, Agrostis nigra. Glyceria plicata, Bromus erectus, 

 many Rubi and Roses, a few Hieracia. Willows, etc. Several new species 

 of Chara and a Nitella have also been found. 



A remarkable occurrence so far from the sea is that of Aster tripolium 

 which was discovered in August 1905 by the warping drain near Misson, 

 in company with Scirpus maritimus. This warping drain is connected 

 with the Trent near Owston, and as the river is tidal for many miles above 

 this spot it may well be that the presence of these two maritime plants 

 is due to natural causes. On the other hand the North American Mimulus 

 langsdorffii is an escape from cultivation which attracts the attention of 

 the most casual observer by its abundant, large and showy flowers : it is 

 becoming naturalised in many places in the northern part of the county. 

 Another North American introduction, not seen by any of the earlier 

 Notts, botanists, is Matricaria suaveolens. a shabby-looking weed which 

 has extended so rapidly in recent years as to be abundant in waste ground 

 all over the county. 



The number of flowering plants and vascular cryptogams recorded as 

 native or fully naturalised in Nottinghamshire is about 860, but this does 

 not include any of the numerous so-called ' species ' into which such 

 plants as Viola arvensis. Alchemilla vulgaris. Euphrasia officinalis, etc., 

 have recently been subdivided; many of these occur with us, but have
