A HISTORY OF BERKSHIRE 



Scirpus nanus, S. cernuus, Carex punctata, Cyperus longus and Scirpus 

 Taberncemontanus. 



Berkshire therefore lacks many plants possessed by Hampshire, but 

 several are confined to the New Forest, others are limited to the neigh- 

 bourhood of Fleet Pond and the bogs of the neighbourhood, while the 

 southern chalk downs afford Carex bumilis and Phyteuma orbiculare not yet 

 detected on our chalk range. There are reported for Berkshire, on the 

 other hand, several species which do not appear to be recorded for the 

 larger county. The chief of these are Anemone Pulsatilla, Sisymbrium 

 Sophia, Roripa syhestris (Nasturtium syhestre), Eropbila prcecox, Geranium 

 rotundifolium, Astragalus danicus, Callitriche polymorpha, Crepis biennis, C. 

 fcetida (?), Pimpinella major, Rosa agrestis (R. septum], R. glauca, Limnan- 

 themum peltatum (Villarsia), Verbascum Lychnitis, Mentba piperita, Teucrium 

 Scordium, Galeopsis speciosa, Calamintba parvifolia (C. Nepeta), Illecebrum 

 uerticillatum, Orchis militaris, O. Simla (? extinct), Leucojum czstivum, 

 Valerianella carinata, Senecio squalidus, Cbenopodium opulifolium, Ornithoga- 

 lum pyrenaicum, Potamogeton coloratus (P. plantagineus], P. Drucei, P. com- 

 pressum (P. zoster cefolius], P. prcelongus, Zannichellia maritima, Carex 

 Baenninghausiana, Alopecurusfuhus, Festuca rubra var. fallax, Poa Chaixii, 

 Tolypella intricata, T. glomerata and T. prolifera. 



Compared with the flora of Berkshire the flora of Wiltshire will be 

 found to be considerably poorer in the number of recorded species, but 

 Wiltshire has several plants which are not on authoritative record for our 

 county. Those in square brackets however appear to require recent 

 confirmation. The chief of these plants recorded for Wilts not pos- 

 sessed by us are Ranunculus tripartitus (possibly in Berks), Cerastium 

 pumilum, \Cardamine impatiens~\, Thlaspi perfoliatum (casual in Berks), 

 Linum angustifolium, Chrysosplenium alternifolium, Cnicus tuberosus, (Enanthe 

 piminelloides, Phyteuma orbiculare, Campanula latifolia, C. patula (casual in 

 Berks), Orobanche Hedercz, Pinguicula lusitanica, Mentha rotundifolia, [M. 

 pratensis], Melittis Melissophyllum, Asarum, Cephalanthera ensifolia, Ophrys 

 aranifera, Polygonatum officinale [Potamogeton gramineum (heterophyllus]\, 

 Cyperus longus, [Eriophorum vagina turn], Scirpus Tabernamontani, Carex 

 digitata, C. humilis, C. tomentosa, [C. diandra (C. teretiuscu/a)], Bromus 

 madritensis, Phegopteris calcarea and [Festuca syhatica~\. 



Berkshire has upwards of eighty species not recorded for Wiltshire. 



East Gloucestershire has several species which are either not recorded 

 for or are extinct in Berkshire ; among these are Vicia Orobus, Rubus 

 saxatilis, (Enanthe pimpinelloides, Mentha pubescens auct. angl. Cephalanthera 

 rubra, C. ensifolia, Polygonatum officinale, Melittis Melissophyllum, Carex 

 digitata, Lycopodium alpinum var. decipiens (L. complanatum var. fallax}, 

 Carex tomentosa, Ranunculus ophioglossifolius (now extinct), Thlaspi per- 

 foliatum (casual in Berks), Cerastium pumilum, Chrysosplenium alternifolium, 

 Epilobium Lamyi (?), Campanula latifolia, Cynoglossum montanum, Mentha 

 rotundifolia, Cystopteris fragilis and Phegopteris calcarea. The records of 

 Linum angustifolium, Prunus Padus, Melica nutans, Eriophorum "vaginatum 

 and Orobanche Hederce appear to need confirmation.
