 BOTANY (C. 'ventricosa], C. Jiava var. cyperoides, C. Jiliformis, Homalocenchrus (Leersia}, Gastridium, Deschampsia discolor (D. setacea), Bromus madritensis, Equisetum litorale (a hybrid), E. hyemale, Char a aspera and Nitella gracilis. In addition to this somewhat lengthy list there are several brambles of which we lack records for Berkshire but which occur in Surrey, and the two following species although recorded for Surrey appear to need confirmatory evidence, namely Opbrys aranifera and Calamagrostis lanceolata. Berkshire possesses a few species which are not, so far as I am aware, recorded for Surrey : Anemone Pulsatilla, Tunica prolifera, Astragalus danicus, Geum rrvale, G. intermedium (a hybrid), Senecio squalidus, Carduus pycnocepbalus, Cnicus eriopborus, Gentiana gfrmanica, G. campestris, Linaria repens, Pinguicula -vulgaris, Mentha Cardiaca, Teucrium Scordium, Illecebrum verticil latum, Leucojum (estfoum, Ornitbogalum pyrenaicum, Potamogeton coloratus (P. plantagineus], P. Drucei, Zannichellia maritima, Eleocbaris uniglumis, Car ex elata (C. stricta), C. distant, Poa Cbaixii, Phegopteris polypodioides, Tolypella prolifera, T. intricata and Nitella mucronata. In comparing the flora of Berkshire with that of its bordering county of Hampshire, I omit the plants peculiar to the Isle of Wight because Mr. Watson makes that island a separate vice-county, nor do I enumerate the maritime species which the extensive coast line of Hamp- shire affords. The large sylvan tract of the New Forest affords several species which are not found in Berkshire, and we do not possess as native plants the following species : Ranunculus tripartitus (this may occur), R. ophioglossifolius (?), Viola persiccefolia, Silene nutans (casual in Berks), S. quinquevulnera, Cerastium pumilum, Linum angustifolium, Trifolium glomeratum, Vicia Orobus, Latbyrus palustris (? in Berks), Tilia parvifolia (T. cor data], Pyrus scandica (P. rotundifolia var. decipiens], Rosa leucocbroa, R. pimpinelli- fo/ia, Cbrysosplenium alternifolium, Till&a muscosa (? in Berks), Drosera ang/ica, Ludwigia apetala (Isnardia palustris), (Enanthe pimpinelloides, Senecio viscosus, Centaurea Calcitrapa, Gnapbalium luteo-album, Pbyteuma orbiculare, Campanula patula (casual in Berks), Oxycoccos, Microca/a, Pulmonaria angustifo/ia, Bartsia viscosa, Rbinantbus major, Utricularia intermedia, Pin- guicula lusitanica, Veronica spicata (??), M. pratensis, M. gentilis (?), Mentha rotundifolia, Melittis Melissophyllum, Stachys germanica, Rumex limosus, Salix acuminata (hybrid), S. laurina, S. pentandra (??), Herniaria hirsuta (? colo- nist), Ma/axis, Gyrostacbis (Spiranthes] cestivalis, Listera cor data, Acer as (?), Orchis bircina (extinct), Opbrys aranifera, Melampyrum cristatum, M. arvense, Gladiolus, Polygonatum officinale, Sparganium minimum, Potamogeton gramineum (P. beteropbyllus], P. decipiens, Cyperus fuscus, Eriopborum vagina turn, E. gracile, Rynchospora fuse a, Cladium, Car ex diandra (C. teretiuscula), C. limosa, C. humilis, C. montana, C.jia'ua var. cyperoides, C. filiformis, Homalocenchrus (Leersia) Gastridium, Deschampsia discolor (D. setacea), Bromus madritensis, Lycopodium alpinum, Chara connivens and C. aspera. The following plants are not likely to grow in Berkshire from the fact of their usually occurring near the sea, although occasionally found inland : Cerastium tetrandrum, Trifolium sujfocatum, Lotus hispidus, Rubia, 39
