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,
