BOTANY localities in the Breck district. Known at Elden (Elveden) since Ray's time (1677), when it was first noticed as British. Asarum europaeuttl, a very rare woodland species, has been found at Rougham. Thesium humtfusum, flourishing on a chalky soil, may be found on Newmarket Heath and in the Bury and Brandon districts. Watson's Ger- manic type. Euphorbia platyphyllos: Hardwick. Malaxh paludosa : Redgrave Fen. LtpariS Loesehl : An interesting epiphyte, very uncertain in its appearance year by year, found in spongy bogs as at Redgrave, Thelnetham, Lakenheath, and Tuddenham. For- merly found in Kent and Huntingdonshire, and still growing in Cambridgeshire, Glamor- ganshire, Carmarthenshire, and Norfolk ; I saw it in the last county in 1900 (see Trans. Norf. and Norw. Nat. Sac. vii, 333). Orchis UStulata : Germanic. Newmarket Heath, Dalham, and near Cavenham. Ophrys aranifera : Germanic. Kennett, and in the Saxham and Sicklesmere neighbourhoods ; rare. HerminiutTl monorchtS .' Germanic. Around Little Saxham and Sicklesmere. Muscarj racemosum : This East Anglian species is only found in a wild state in Norfolk, Suffolk, and Cambridgeshire. First dis- covered as a British plant at Cavenham and Hengrave in 1805 ; it also occurs in fallows and plantations in a few other stations in the Breck district, funcus compressus : Livermere Lake and Barnham. Potamogetotl ZOsteraefoHus: Ditch near River Lark, 2 miles from Prickwillow. P . trichotdes : Tuddenham, Barton Mere, and Wortham Long Green. Carex paradoxa : Near Icklingham St. James and at Market Weston. (For the distri- bution of this plant, sparing but wide, see Trans. Norf. and Norw. Nat. Soc. vii, 695.) C. ertcetorum : A dwarf early-flowering species, only known to occur in West Suffolk, West Norfolk, and Cambridgeshire. It grows at Mildenhall, Icklingham, and near Risby. Panicum glabrum : A local annual of sandy fields, occurring near Bury, though possibly not a true native of the county nor of England. Only found in Suffolk, Norfolk, Hampshire, and Surrey. Germanic. Phleum phalaroides ." Germanic type. Found only in six eastern counties. It grows in about half-a-dozen places in the Breck district, as Milden- hall, Lakenheath, &c. Alopecurus fulvus : Pools near Welnetham. Apera interrupta : Gathered in 1848 near Thetford and then new to England. Subsequently found in many spots in the Breck district, and at Higham, &c., and also in the counties of Essex, Norfolk, and Cambridge. IVeingaertneria canescens : Between Lakenheath and Wangford, and on Lackford Heath. In these localities, and at Homersfield (district 5), it is unique in England as occurring inland ; elsewhere in Suffolk and Norfolk (its only other county) it is a true maritime plant. Festuca ambigua occurs in many places in the Breck district, as Thet- ford, Brandon, Mildenhall, &c. It flowers in May. Cystopteris Jragilis: Old wall near Barton. Equisetum hyemale : About Woolpit and in the Bury neighbourhood. Lycopodium clavatum : Tuddenham Heath, very sparingly; known there since 1773. A very scarce species in Suffolk. 2. Stour This division is in the south-west of the county, is coloured purple on map, and is watered by the River Stour and its numerous tributaries. The greater part of the division is on a chalk sub-stratum with surface soils of chalky Boulder Clay and patches of sand or gravel ; exposed chalk occurs here and there. In the south-east, which may be indicated as lying south of Long Melford, Edwardstone, and Semer, the chalk is overlaid by the Eocene deposits, of which the London Clay is the most important. Still farther to the east these beds are in their turn covered by the red-coloured shelly sands belonging to the Red Crag formation ; these sands, however, rarely come to the surface except on the slopes of the valleys intersecting the district, as they are generally covered by the sands and clays of the Glacial series. A small portion of the banks of the Stour, close to its mouth, produces a few maritime plants. 55
